With the rise in industrial capitalism during the 20th Century, artists increasingly focused on the threat of a disappearing natural world. In the high technology era of the late 20th Century, artists whose practice is termed 'ecological' based their work around new understandings of the relationship between nature and culture, fundamentally underpinned by a shift toward evolutionary, systems-theoretical perspectives from those of conquest and exploitation. Now, at the dawn of the 21st Century, the information era has brought into intersection the discourses of information technologies, quantum physics, and biological science, awakening artists to the challenge of engaging with ecology as the primary subject of their practice. The doctoral project that is the subject of this exegesis focuses critical attention on our scientific and aesthetic understandings of water - a crucial symbolic element of global import in survival. It explores the representation of water in and through art practice that is informed by political ecological awareness and new (digital) technologies. My practice exploits the potential of recent digital technologies to create experiences that aim to encourage a more ecologically sustainable human engagement with nature through this focus on water. This exegesis describes and locates the creative work within an ongoing discourse in contemporary culture that actively seeks to re-establish and redefine the relationship between culture and nature.

This dissertation examines the processes of perception and cognition and demonstrates their application to the creation of aesthetically and artistically significant television content. By reexamining past understandings and assumptions, the ways in which artists and media producers have manipulated the information search and processing faculties of their audiences, and thus guided the meanings they ascribed to still and moving images, are explored. To reflect the multidisciplinary nature of television aesthetics, this research is not limited to a particular academic discipline. Instead, it draws on several streams of research and scholarship (media studies, marketing, psychology, neuroscience, and the fine arts) to bridge the gap between scientific theory and artistic practice and, in turn, develop effective guidelines for the construction of audiovisual materials that fulfill all three functions of the arts: the intensification, clarification, and interpretation of experience.
Cette thèse étudie les processus de perception et de cognition et démontre leurs applications à la création de contenu télévisuel ayant une valeur artistique et esthétique. En réexaminant les connaissances et hypothèses antérieures, les façons dont les artistes et les producteurs de médias ont manipulé les facultés de traitement des informations de leurs auditoires, et donc la signification qu'ils attribuaient à des images fixes et animées, sont explorées. Pour refléter la nature multidisciplinaire de l'esthétique de la télévision, cette recherche ne se limite pas à une discipline académique particulière. Au lieu de cela, elle s'appuie sur divers courants de recherche et domaines d'érudition (études sur les médias, le marketing, la psychologie, les neurosciences, et les beaux-arts) pour combler le fossé entre la théorie scientifique et la pratique artistique, afin de formuler des recommandations visant à la création de matériel audiovisuel qui remplit les trois fonctions de l'art: l'intensification, la clarification, et l'interprétation de l'expérience.

This studio-based research focuses on my visual exploration of ideas about nature, specifically, urban nature. Through my practice of mark making I investigate and find inspiration in the many non-human forms of nature, seen and unseen, on the surfaces and in the margins of cities. Urban ecological thinking has enabled me to argue that cities are natural, and that ideas we continue to hold onto, of a pristine wilderness, do not necessarily help advance our appreciation of, and value for, the nature where we live. This exegesis also discusses a shift in the anti-aesthetic and aesthetic aspects of contemporary art and nature. I discover that there is a shift in the aesthetic appreciation of nature due to an awareness of different forms of nature that we now live with, and even create, like weeds, dust, and pollution. The artists I survey highlight the value of the urban. While they are ecologically aware, they are not overtly environmentalist. This research contributes to the extensive discourse on art and the environment, and about critically thinking about urban nature, and the nature humans create. Throughout, this chronological investigation sets out the changes and shifts in location and resulting studio outcomes. I begin by outlining my exploration of the traces of nature on surfaces of the city, focusing on marks of wear and effects of time, age and decay as aesthetic qualities of desire and nature. These forms of nature are referred to as subnature. I examine concepts of the human/non-human connections through the marks of nature on man-made structures, and of man-made marks on nature. My studio work explores ideas of artificiality by experimenting with surfaces, stains, and mark making, in relation those observed in the urban environment.

The Kingdom of Jordan is one of the world's most water poor countries suffering from physical water scarcity, a growing population, regional instability, poor water infrastructure, inefficient water sector management and high water misuse. Through conducting a content analysis of 73 USAID reports, focusing on water demand management, this paper aims to understand how water demand is managed in the Kingdom, in addition to understanding the role of international aid in transforming Jordan's water sector. A greater understanding of the crisis and actions taken to mitigate the impacts were revealed by examining specific water polices and laws, the role of government structures and water sectors, and implemented projects. It was found that Jordan has taken significant efforts to sustainably manage water resources and to address growing water demand. Reallocating water among various sectors, reducing non-revenue water, and decentralizing water provision are key priorities outlined in the Kingdom's water strategy.

Streszczenie:

Sustainable management of the existing built environment is becoming increasingly important in the construction industry. Consequently, more emphasis has emerged to consider issues of refurbishment and renovation. The aesthetic values of buildings are recognised as critical guiding attributes both in terms of the potential long-term aspects of sustainability and as basic reasoning for the continued maintenance and management of existing buildings. A process is required that will allow different aspects of a potential refurbishment project to be assessed objectively and weighted equally when deciding whether an existing building should be preserved, adapted or demolished. The thesis attempts to provide a useful understanding in terms of the aesthetic appreciation when considering future sustainable management of the existing built environment. Two parallel research activities were initiated to examine important aspects of human aesthetic perception regarding buildings in the built environment. The first addressed the potentially universal and culturally derived aspects of human responses in perceiving the aesthetic qualities of houses from 3 counties through the agency of colour photographs. A three language semantic differential scale was developed to be linguistically equivalent so that an inter-cultural research tool could be derived to ascertain an understanding of people’s aesthetic appreciation through the use of descriptive adjectives. The second activity was initiated to develop and test the concept of building endurance regarding the general public’s aesthetic appreciation of existing buildings. A methodological framework was developed to facilitate investigation of changes of human aesthetic response related to changes in the built environment. Cross-cultural variables and respondent’s age parameter were found to be influential in conditioning people’s aesthetic responses to photographs of houses and urban streetscapes. Few differences were observed between male and female aesthetic responses both in their descriptions of visual quality and their ideal house profile. A cross-cultural, universal profile of ideal house qualities was obtained by utilizing responses from the cross-language semantic differential scale. However differences in people’s aesthetic preference selections were observed. Additionally, respondents’ preference rankings demonstrated that the general public supports the desire of preserving the existing urban condition. Appropriate refurbishment strategies were suggested to guide decision making when assessing changes to be made to an existing building and its surrounding environment while at the same time maintaining people’s aesthetic appreciation. The research activities presented in this thesis provide a contribution to current knowledge of the general public’s aesthetic appreciation of the existing buildings and built environments which may be used to aid future sustainable development of the built environment.

Streszczenie:

Traditional mentor relationships were examined from the perspective of those who work in the creative arts, with a view to establishing the meaning of the relationship and its relevance to human development, psychological well-being, and self-actualisation. The study aimed to examine whether initial research findings in the area of traditional mentoring were transferable (Bennetts, 1994), and sought to produce insight into the metaphysics of the relationship. The term 'mentor' is an honorary title bestowed by a learner. Such relationships form naturally, have a defined pattern and conditions, and promote personal development for both mentor and learner. Thirty five individuals drawn from a variety of creative arts fields were interviewed using a qualitative hermeneutical and heuristic approach. Peak experience and performance are discussed and examined, together with creativity, mental health, and relationship issues. A practical and theoretical interpersonal course for adult learners and derived from initial mentor research, is described and evaluated. Continuing mentor relationships are learner-centred, and are based on trust, respect, and a component encompassing many types of love. If the power within a mentor alliance is abused by the mentor, the mentoring aspect of the relationship ends, although any prior relationship may still continue. Mentor relationships exhibit Rogers' core conditions for learning, and Rogers' conditions for creativity, and this finding both supports and enhances Bennetts' 1994 study. Mentors were shown to promote psychological well-being in childhood, adolescence and adulthood, and also support the self-image, self-esteem and self-worth of the artist. The mentor relationship is described as an art-form, as the mentor utilises an aesthetic communication approach to the artist and the artist's work. Such a description enables the metaphysics of the traditional mentor relationship to be understood in depth. The traditional mentor alliance is viewed as a valid and vital relationship for continuing education and learning.

Cataloged from the official PDF of thesis.
Includes bibliographical references (pages 78-82).
There are nearly 1 billion people who obtain their drinking water through piped distribution networks that operate intermittently. Intermittent Water Supply (IWS) operations allow for periods of stagnation and depressurization that create conditions favorable for biofilm growth on pipe surface. Biofilms are complex microbial communities that are likely sources of opportunistic waterborne pathogens and can cause disease outbreaks. Flushing of the water pipes and re-pressurization, which occur at the start of each IWS supply cycle, cause the erosion of the biofilm and its transport into the bulk water, which can potentially contaminate the drinking water. This thesis describes the development and proof-testing of an experimental pipe testbed installed on the Nanyang Technological University (NTU) campus in Singapore.
The testbed comprises an array of 100 mm diameter PVC pipes, supplied from a water tank with flow paths controlled through a set of valves, and water samples obtained at up to 7 pipe outlets. Data are presented from an initial program of tests that compare the effects of priming for two pipe sections: 1) with continuous laminar flow (Continuous Water Supply, CWS) under pressure; and 2) IWS, where the pipe section is flushed during re-pressurization (supply period) and then allowed to drain and stagnate for the remainder of the daily cycle. The change of the water quality from both the inlet and outlet was evaluated by determining the microbial load using flow cytometry (with Live/Dead staining), together with physical and chemical water parameters measured on a time series of water samples.
The data compare the response of the CWS pipe section for steady laminar flow, with the transient response following a step-change in flow rate (turbulent conditions) with transient behavior during flushing of the IWS section. Initial filling of the IWS section cause a significant increase in total and live cell counts, confirming that erosion of biofilm can contribute to biomass transported in the bulk water. Further tests are in progress to validate and replicate these results.

Artificial photosynthesis is achieved by placing a semiconductor in water, where photoexcited charges generate a photovoltage at the surface of the semiconductor. However, solar to fuel efficiencies of earth abundant metal oxides and metal nitrides remain limited by their low photovoltages. Many different treatments have been used to improve the photovoltages of semiconductors, such as photocharging, surface regrowths, or the addition of heterogeneous catalysts. However, in these treatments, it remains unclear whether the enhanced photovoltage arises from improved kinetics or energetics. In many of the following studies, the surface kinetics of different semiconductors are measured in order to quantify how surface kinetics are related to the photovoltage of these materials. Different spectroscopic measurements are made along with detailed analysis of the Fermi level and quasi Fermi level in order to corroborate the kinetic data with energetic data. Together, this dissertation explores a multitude of methods and procedures that demonstrate how the photovoltage of semiconductors can be understood and manipulated for photoelectrochemial artificial photosynthesis

Streszczenie:

There is an increasingly water scarcity issue, both for developed and developing countries. Water authorities are facing the challenges to secure the need of consumers and water saving due to the climate change and the population increase. To manage this water scarcity threat, water conservation projects are gaining overall attendances by water utilities and government. From the management perspective, it is desirable to investigate and understand how consumers use water and their water use behaviours. The main objective of this study is to develop a comprehensive understanding of residential household water use behaviour through theoretical and modelling perspectives. This study is based on the Theory of Planned Behaviour (TPB) and proposed an extended version of the Theory of Planned Behaviour (TPB) for understanding the behaviour intervention mechanism. A survey of residential water use behaviour in China was designed and conducted in 2014 and the data was used to evaluate the extended theory. The theoretical evaluation has proved that the ETPB could increase the predictive power compared to original version of TPB, and also provide empirical evidence for the correlations among ETPB variables. Traditionally, static behaviour intervention models are widely utilised to simulate behaviour intervention process. These static methods can predict targeted human behaviour reasonably well, but they lack capabilities on understanding and responding behaviour change process with concerned time changes. Using the proposed ETPB theory, a dynamic behaviour intervention model for household water use behaviour prediction is presented to introduce the dynamic behavioural modelling solution. This model is based on adopted Structure Equation Model approach and Control Engineering Concept. A case study for household water consumption model using Artificial Neural Network (ANN) is proposed to explore the link between behaviour value and the water consumption amount, moreover, for evaluation of intervention trend of proposed ETPB dynamic behaviour model with system parameter identification. This research findings demonstrated that household water consumption could be saved by using proper behaviour change management strategies. The significance of these findings about behaviour intervention modelling in water end use areas is discussed. Also, potential applications of the ETPB-ANN dynamic integrated modelling method for other research purpose are also presented.

Streszczenie:

Effective coagulation is critical to the production of safe, potable drinking water, but variations in the chemical composition of source water can present challenges in achieving targeted contaminant removal and predicting coagulation outcomes. A critical literature review describes factors affecting the hydrolysis reactions of metal salt coagulants and the resulting precipitates. Properties of two key contaminants, turbidity and natural organic matter (NOM), are explored in the context of removal during coagulation, and the influence of co-occurring ions is described. While it is apparent that NOM character determines the minimum achievable organic carbon residual, the effects of water quality—including pH, NOM character and concentration, and concentrations of synergistic and competitive ions—on overall coagulation efficacy and NOM removal may be underestimated. An experimental research plan was devised to investigate the influence of water quality in coagulation and provide data to support the development of a predictive coagulation model. NOM is capable of interfering with ferric iron hydrolysis and influencing the size, morphology, and identity of precipitates. Conversely, calcium is known to increase the size and aggregation of Fe3+ precipitates and increase surface potential, leading to more effective coagulation and widening the pH range of treatment. Experiments and modeling were conducted to investigate the significance of the Fe/NOM ratio and the presence of calcium in coagulation. At the high Fe/NOM ratio, sufficient or excess ferric hydroxide was available for NOM removal, and coagulation proceeded according to expectations based upon the literature. At the low Fe/NOM ratio, however, NOM inhibited Fe3+ hydrolysis, reduced zeta potential, and suppressed the formation of filterable Fe flocs, leading to interference with effective NOM removal. In these dose-limited systems, equilibrating NOM with 1 mM Ca2+ prior to dosing with ferric chloride coagulant increased the extent of Fe3+ hydrolysis, increased zeta potential, decreased the fraction of colloidal Fe, and improved NOM removal. In dose-limited systems without calcium, complexation of Fe species by NOM appears to be the mechanism by which coagulation is disrupted. In systems with calcium, data and modeling indicate that calcium complexation by NOM neutralizes some of the negative organic charge and minimizes Fe complexation, making Fe hydrolysis species available for growth and effective coagulation. Experiments were conducted to investigate the influence of aqueous silica and pH on the removal of natural organic matter (NOM) by coagulation with ferric chloride. Samples with preformed ferric hydroxide were also compared to samples coagulated in situ to assess the role of coprecipitation. The moderate (10 mg/L) and high (50 mg/L) SiO2 concentrations both demonstrated interference with NOM removal at pH 6.5-7.5. In turn, NOM at 2 mg/L as DOC interfered with silica sorption at the moderate silica level and in samples with preformed ferric hydroxide at the high silica level. The combination of NOM and high silica led to decreases in DOC sorption and unexpected increases in silica sorption in the coprecipitated samples. The fraction of colloidal Fe passing a 0.45-μm filter also increased in the coprecipitated samples with both NOM and high silica. It is hypothesized that the combination of NOM and high silica synergistically interfered with Fe precipitation and particle growth processes, with NOM having the greater effect at lower pH and shorter reaction times, and silica exerting greater influence at higher pH and longer reaction time. Direct competition for surface sites and electrostatic repulsion were also influential. An overall goal for this research was the development of a quantitative coagulation model. Previous attempts to model coagulation have been limited by the inherent complexities of simultaneously predicting ligand sorption, metal complexation, floc surface charge, and particle removal. A diffuse layer (DLM) surface complexation model was formulated to simultaneously predict sorption of NOM and other key species, including silica, calcium, and carbonate alkalinity. Predictions of surface potential were used to estimate zeta potential and resulting regimes of effective aggregation and turbidity removal. The model provided good predictive ability for data from bench-scale experiments with synthetic water and jar tests of nine U.S. source waters. Under most conditions, the model provides excellent capability for predicting NOM sorption, calcium sorption, and particle destabilization and adequate capability for predicting silica sorption. Model simulations of hypothetical scenarios and experimental results help to explain practical observations from the literature. The DLM can be optimized to site-specific conditions and expanded to include sorption of additional species, such as arsenic.

Streszczenie:

For decades, cement mortar relining has been used successfully to extend the life of drinking water pipelines, although, few quantitative data exist on the short-term water quality impacts of this process. This study investigated mortar lining impacts on disinfectant by-product formation, alkalinity, metal leaching, pH and disinfectant consumption, and odor generation shortly after in-situ installation. The experimental design used a 30-day, coupon immersion procedure that simulated a relined 4-inch diameter pipe located in a low-flow system. Four water regimes were utilized; no disinfectant, chlorine (2 mg/L at pH 6 .5 and 8), and chloramines. Flavor Profile Analysis panels evaluated odors of samples and controls. Additionally, the affects of three different phosphate-based corrosion prevention additive regimes were evaluated. Cement mortar leachates impacted water quality significantly during the first week of exposure. Alkalinity, hardness and pH increased dramatically after initial exposure, rising to approximately 600 mg/L as CaCO3 alkalinity, 770 mg/L as CaCO3 hardness, and pH 12 in the first two days. Sharp declines in alkalinity and hardness did not occur until after day 9 when the cement mortar was substantially cured and release of calcium hydroxide lessened. Chlorinated water residual disinfectant decay rate was increased substantially during the initial 24 hours and remained elevated until day 9. After day 1, there was not a significant increase in the formation of regulated haloacetic acids or trihalomethanes. Significant levels of aluminum (< 700 ug/L) and chromium (< 75 ug/L) were released at various times during the test period but their concentrations did not exceed USEPA water quality standards. Cement odor intensity levels were significantly higher than controls, persisted for 14 days, and were of an intensity that would be readily noticeable to consumers. The polyphosphate-based corrosion preventative resulted in less severe water quality effects than other phosphate additives or water without added phosphate.

Streszczenie:

Governance has emerged as one of the key concerns amongst water experts focused on sustainability. Achieving sustainable states of water governance requires alignment of governance structures with water management objectives that are context specific. Two rural watershed planning processes in the province of British Columbia- the Similkameen Valley (Similkameen) Watershed planning network and the Kettle River (Kettle) Watershed planning network - were investigated using social network analysis (SNA) and social discourse network analysis (s-DNA) to map the socio-ecological relationships and analyze the discourse upon which water governance networks are being built. The resulting network structures and key actor characteristics revealed limited evidence for a transition towards collaborative and adaptive water governance models, which have been argued to be better suited in addressing key goals such as adapting to climate change impacts. Recommendations are made for improving water governance processes in rural regions to achieve effective implementation within the context of the new British Columbia Water Sustainability Act, 2014. SNA and s-DNA provide a means, through interdisciplinary research, to examine social network drivers and potential barriers to sustainable water governance development. Identifying network structures and measuring network characteristics gives resource managers the insight to intervene into evolving governance processes, to ensure proper alignment with contextually determined water sustainability goals. Results from this research will enable those involved in water governance design and implementation to make informed water resource decisions leading to effective, adaptive, and sustainable water governance.

Streszczenie:

With the increasing degradation of rivers worldwide, an understanding of spatial and temporal patterns in freshwater quality is important. Water quality is highly variable in space and time, yet this is largely overlooked at the scale of stream catchments. I employed a landscape ecology approach to examine the spatial patterning of water quality in complex, impacted stream networks on the Canterbury Plains of the South Island of New Zealand, with the goal of understanding how land-use effects proliferate through stream systems. In particular, I used “snapshot” sampling events in conjunction with spatial modelling and longitudinal profiles to investigate the ways in which spatial and environmental factors influence the variability of water quality in stream networks. Spatial eigenfunction analyses showed that distance measures, which took into account variable connectivity by flow and distance along the stream between sites, explained more spatial variance in water quality than traditional distance metrics. Small upstream reaches were more spatially and temporally variable than main stems (under summer base-flow conditions). The extent of spatial variation in water quality differed between stream networks, potentially depending on linkages to groundwater and the surrounding landscape. My results indicated that the water quality of headwater streams can have a disproportionate influence over water quality throughout an entire network. I investigated spatio-temporal patterns in water quality more intensively in one stream network, the Cam River, in which I found consistent spatial pattern through time. The relative balance between nutrient inputs (pollution and groundwater) and in-stream conditions influenced the spatial pattern of water quality, as well as that of several ecosystem processes which I measured simultaneously. The spatially intensive and explicit approach has allowed identification of key factors controlling water quality and ecosystem processes throughout the Cam River. This research highlights the importance of taking a spatially explicit approach when studying stream water quality and that such an approach could be insightful and will contribute to solving current stream management problems.

Streszczenie:

The connections between surface water and groundwater systems remain poorly understood in many catchments throughout the world and yet they are fundamental to effectively managing water resources. Managing water resources in an integrated manner is not straightforward, particularly if both resources are being utilised, and especially in those regions that suffer problems of data scarcity. This study explores some of the principle issues associated with understanding and practically modelling surface and groundwater interactions. In South Africa, there remains much controversy over the most appropriate type of integrated model to be used and the way forward in terms of the development of the discipline; part of the disagreement stems from the fact that we cannot validate models adequately. This is largely due to traditional forms of model testing having limited power as it is difficult to differentiate between the uncertainties within different model structures, different sets of alternative parameter values and in the input data used to run the model. While model structural uncertainties are important to consider, the uncertainty from input data error together with parameter estimation error are often more significant to the overall residual error, and essential to consider if we want to achieve reliable predictions for water resource decisions. While new philosophies and theories on modelling and results validation have been developed (Beven, 2002; Gupta et al., 2008), in many cases models are not only still being validated and compared using sparse and uncertain datasets, but also expected to produce reliable predictions based on the flawed data. The approach in this study is focused on fundamental understanding of hydrological systems rather than calibration based modelling and promotes the use of all the available 'hard' and 'soft' data together with thoughtful conceptual examination of the processes occurring in an environment to ensure as far as possible that a model is generating sensible results by simulating the correct processes. The first part of the thesis focuses on characterising the 'typical' interaction environments found in South Africa. It was found that many traditional perceptual models are not necessarily applicable to South African conditions, largely due to the relative importance of unsaturated zone processes and the complexity of the dominantly fractured rock environments. The interaction environments were categorised into four main 'types' of environment. These include karst, primary, fractured rock (secondary), and alluvial environments. Processes critical to Integrated Water Resource Management (IWRM) were defined within each interaction type as a guideline to setting a model up to realistically represent the dominant processes in the respective settings. The second part of the thesis addressed the application and evaluation of the modified Pitman model (Hughes, 2004), which allows for surface and groundwater interaction behaviour at the catchment scale to be simulated. The issue is whether, given the different sources of uncertainty in the modelling process, we can differentiate one conceptual flow path from another in trying to refine the understanding and consequently have more faith in model predictions. Seven example catchments were selected from around South Africa to assess whether reliable integrated assessments can be carried out given the existing data. Specific catchment perceptual models were used to identify the critical processes occurring in each setting and the Pitman model was assessed on whether it could represent them (structural uncertainty). The available knowledge of specific environments or catchments was then examined in an attempt to resolve the parameter uncertainty present within each catchment and ensure the subsequent model setup was correctly representing the process understanding as far as possible. The confidence in the quantitative results inevitably varied with the amount and quality of the data available. While the model was deemed to be robust based on the behavioural results obtained in the majority of the case studies, in many cases a quantitative validation of the outputs was just not possible based on the available data. In these cases, the model was judged on its ability to represent the conceptualisation of the processes occurring in the catchments. While the lack of appropriate data means there will always be considerable uncertainty surrounding model validation, it can be argued that improved process understanding in an environment can be used to validate model outcomes to a degree, by assessing whether a model is getting the right results for the right reasons. Many water resource decisions are still made without adequate account being taken of the uncertainties inherent in assessing the response of hydrological systems. Certainly, with all the possible sources of uncertainty in a data scarce country such as South Africa, pure calibration based modelling is unlikely to produce reliable information for water resource managers as it can produce the right results for the wrong reasons. Thus it becomes essential to incorporate conceptual thinking into the modelling process, so that at the very least we are able to conclude that a model generates estimates that are consistent with, and reflect, our understanding (however limited) of the catchment processes. It is fairly clear that achieving the optimum model of a hydrological system may be fraught with difficulty, if not impossible. This makes it very difficult from a practitioner's point of view to decide which model and uncertainty estimation method to use. According to Beven (2009), this may be a transitional problem and in the future it may become clearer as we learn more about how to estimate the uncertainties associated with hydrological systems. Until then, a better understanding of the fundamental and most critical hydrogeological processes should be used to critically test and improve model predictions as far as possible. A major focus of the study was to identify whether the modified Pitman model could provide a practical tool for water resource managers by reliably determining the available water resource. The incorporation of surface and groundwater interaction routines seems to have resulted in a more robust and realistic model of basin hydrology. The overall conclusion is that the model, although simplified, is capable of representing the catchment scale processes that occur under most South African conditions.

Using Ningxia Hui Autonomous Region in China as a case study, the thesis addresses the interconnectedness between water and energy and investigates the regional water-energy nexus to assess the coherence of relevant policies and to explore opportunities to achieve sustainable development. Ningxia is extremely scarce in water but abundant in coal. On one hand, the government sets stringent targets to conserve water; on the other hand, the region has ambitious plans to develop the water intensive coal and relevant industries. Based on current development status and policies, the water and energy systems are modeled by WEAP and LEAP, respectively. The regional water-energy nexus is mapped to reveal the interactions between water and energy sectors. From the water policies, it is estimated that the water demand would decrease slightly in 2015; from the energy policies, the energy demand and production would increase greatly. Through the nexus approach, it is found that while energy is abundant to satisfy the increasing demand by the water sector for production and supply, water, however, cannot support the aggressive energy development. The huge water deficit indicates the potential incoherence of current policies and the unsustainable development mode. Nevertheless, there are opportunities to secure resources sustainability. This thesis highlights the viability of the water-energy nexus approach for comprehensive cross-sectorial assessment in policy making and resource management.

Streszczenie:

Although several research groups have studied the formation of H2, both experimentally and computationally, few have explored the surface formation of more complex molecules. A small number of these reactions produce molecules that remain on the surface and, over time, lead to the formation of icy mantles coating interstellar dust grains. The most abundant of these species within the ice is H2O. The first half of this thesis introduces the construction and characterisation of the new dual atomic beam apparatus built to explore the surface formation mechanism of H2O. The apparatus has been designed to enable singular or dual atomic or molecular oxygen and hydrogen beams to be adsorbed onto a range of astronomically relevant substrates. Analysis of the surface chemistry can be performed using a combination of temperature programmed desorption, molecular beam modulation spectrometry, quartz crystal microgravimetry and reflection-adsorption infrared spectroscopy techniques. The remainder of this thesis discusses the results obtained by performing temperature programmed desorption experiments. Kinetic analysis was deduced for: H2O on bare silica; O2 on bare silica; O2 on compact amorphous solid water on silica; and O2 on porous amorphous solid water on silica. The results obtained were used towards constructing a simulation model mimicking the desorption of O2 from the icy mantles of interstellar dust grains under dense molecular cloud environments. The analysis revealed that sub-monolayer coverages of O2 followed first order desorption kinetics with a range of desorption activation energies from all of the surfaces studied. Multilayer coverages of O2 from silica were unexpectedly found to follow fraction order kinetics. Further experiments were performed to explore the origins of this multilayer fractional desorption order. The results obtained revealed that the kinetic order decreased roughly by half as the species change from O2 to CO to N2 suggesting the underlying amorphous silica surface appeared to be the cause for this unusual observation. Preliminary atomic O beam TPD experiments had also been performed from a range of astronomical relevant surfaces. The initial results indicated that O2, O3, H2O2 and 13CO2 were formed on the surface. However, the exact surface formation mechanism could not be concluded from these single experiments.

We explore the relationship between water security (WS) and adaptive capacity (AC); the two concepts are connected because achieving the first may be dependent on building the second. We focus on how metrics of WS and AC are operationalized and what implications they may have for short and long-term management. We argue that rather than static conceptualizations of WS and AC, we need to understand what combinations of capacities are needed as a function of how controllable key parameters of WS are and the types of outcomes we seek to achieve. We offer a conceptual model of the relationship between WS and AC to clarify what aspects of human-water interactions each concept emphasizes and suggest a hypothetical example of how decision-makers may use these ideas.

As the human population increases, the way we use and manage our supply of drinking water becomes even more important. The purpose of this study was to determine residents’ satisfaction level of and performance rating of new water savings devices installed in their apartments. Specifically the investigation focused on ratings of shower heads, kitchen faucet aerators, bath faucet aerators, and fill valve and flapper systems. This quantitative survey included residents at 4 apartment complexes in Tennessee using a paper questionnaire (N = 626). The participants were grouped by age, ethnicity, gender, and whether or not they had experienced both nonrestrictive devices or restrictive low flow devices within their apartment. An independent samples t test was conducted from the research questions for each of these 4 groups. The testing variables for each group consisted of the overall performances of the low flow devices, and the satisfaction of the time to get hot water to shower heads and faucets. There was no significant difference between the 4 grouping variables; residents aged 62 and over compared to 61 and younger, males compared to females, whites compared to nonwhites, and those who had experienced both nonrestrictive and restrictive devices while living in the same apartment when compared to these variables; performance rating of low flow shower heads, kitchen faucet aerators, bath faucet aerators, and low flow toilet devices. The variables also included the satisfaction rating of the time needed to get hot water to the new low flow shower heads and kitchen and bath faucet aerators. These findings support the effort to save clean water and reduce water and sewer costs by installing low flow shower heads, bath and faucet aerators, and water saving toilets. Mean score suggest satisfactory ratings were encountered in every testing category and within every group. In particular, the satisfactory mean score of residents who experienced both nonrestrictive and low flow devices while in the same apartment led to the conclusion that the reduction of water can be achieved satisfactorily in all types of residences.

Stormwater management within the urban context has evolved over time. This evolution has been categorized by five paradigm shifts (Novotny, Ahern, & Brown, 2010). The current paradigm of stormwater management utilizes hard conveyance and treatment infrastructure designed mainly to provide protection for people from typical 1-5 year frequency storms. Consequently, this infrastructure is sometimes unable to deal with larger sized, 50 to 100 year events which can have serious consequences. Manhattan, Kansas has suffered multiple flooding episodes of severe proportion in the past decade. The dilemma of flooding within the Wildcat Creek watershed is a direct example of the current paradigm of stormwater management. This once ecologically healthy corridor is fed by conveyance systems that do not address the hydrologic needs of the watershed; decreasing the possibility for infiltration and groundwater recharge. Vegetated stormwater management systems must be implemented to help increase infiltration and address flooding problems within the Wildcat Creek watershed. The aesthetic performance of designed landscapes has a tremendous effect on the appreciation and care given to them by the surrounding population (Gobster, Nassauer, Daniel, and Fry, 2007). Landscape architecture has the ability to aid in the visual appeal and ecological design of vegetated stormwater management systems (SMS) by utilizing existing frameworks that address aesthetic reaction of the outdoor environment (Kaplan, Kaplan, and Ryan, 1998). This document evaluates design alternatives of vegetated SMS in order to discern a set of variables that inform the relationship between each systems aesthetic and amenity performance and their ecosystem and hydrological performance. Identified variables are combined into a set of guidelines for achieving different levels, or patterns of aesthetic performance found within the Understanding and Exploration Framework et al. (Kaplan, Kaplan, and Ryan, 1998) and amenity performance listed by Echols and Pennypacker’s Amenity Goals et al. (2007) through vegetated SMS. These design guidelines illustrate how aesthetic theory can be applied through ecological systems in order to increase the coherence, legibility, complexity, and mystery (Kaplan & Kaplan, 1989) of existing sites. Creating spaces where ecological and socio-cultural activities can coexist addresses the local characteristics of aesthetics with the universal dilemma of stormwater management.

Streszczenie:

A fundamental focus in ecology is understanding interactions between environmental heterogeneity and ecological community structure, both of which are currently undergoing unprecedented alterations due to global change. In particular, many freshwater phytoplankton communities are experiencing multiple global change stressors, altering phytoplankton community composition, biomass, and spatial distribution. I used multiple approaches to characterize the interactions between spatial distribution and community structure of phytoplankton and quantify uncertainty in predictions of phytoplankton temporal dynamics. First, I analyzed data from 51 lakes to determine the environmental drivers of phytoplankton vertical distributions across the water column for different phytoplankton groups. I show that the relative importance of environmental drivers varies according to the functional traits of each phytoplankton group. Second, I conducted whole-ecosystem experiments in a reservoir to assess phytoplankton responses to surface water mixing events, which may become more prevalent as storms increase under global change. My results demonstrate that aggregated phytoplankton biomass has inconsistent responses to mixing over the short term, but responses of morphology-based functional groups of phytoplankton to mixing are more predictable. Third, I conducted a long-term whole-ecosystem experiment to assess phytoplankton responses to changes in water column thermal gradients which are predicted to increasingly occur under global change. I found that phytoplankton depth distributions responded similarly to thermal gradient disturbance over multiple years, and changes in depth distributions were related to changes in community composition. Fourth, I produced weekly hindcasts of phytoplankton density in a lake for two years to determine the dominant sources of uncertainty in phytoplankton density predictions. I found that better estimation of current phytoplankton density improved representation of error in phytoplankton models, and incorporation of additional life history stages to model structure may improve phytoplankton predictions. Overall, my dissertation chapters demonstrate that the vertical distribution and community structure of phytoplankton are linked, and that the interaction of phytoplankton community structure with environmental heterogeneity is more predictable over longer-term (e.g., months to years) than shorter-term (e.g., days to weeks) scales. My research emphasizes that consideration of phytoplankton community dynamics and the uncertainty associated with phytoplankton predictions are needed for freshwater management under global change.
Doctor of Philosophy
Freshwater phytoplankton, which are microscopic primary producers, are experiencing many environmental changes in lakes and reservoirs due to global change. This includes changes in water temperature, which affects phytoplankton growth and the types of phytoplankton that are present in the water. As a result, phytoplankton communities are changing in ways that affect water quality. For example, phytoplankton may grow rapidly and form blooms which cause unsightly surface scums, clog filters at water treatment plants, or release toxins. My dissertation research uses ecosystem experiments, computer modeling, and large datasets from many lakes to study how the interactions between phytoplankton and their environment might change due to human activities. I found that it is difficult to predict how phytoplankton will respond to changes in water temperature over the short term (days to weeks), but that longer-term (months to years) responses to water temperature changes are more predictable. I also found that the types of phytoplankton present in the water vary across depth in response to light, temperature, and predation. Since the species of phytoplankton that are present determine a waterbody's water quality, my results indicate that water quality can vary substantially among different depths. Finally, I found that the greatest sources of uncertainty in predicting phytoplankton are due to the challenges in accurately measuring the amount of phytoplankton that are present in a lake and representing complex phytoplankton processes in computer models. My research demonstrates that it is important to think about multiple types of phytoplankton and how they interact with the environment, not just the total amount of phytoplankton present, when predicting how water quality will change due to global change. In addition, it is important to consider the uncertainty associated with predictions of phytoplankton when we make decisions about how to manage water quality.

Streszczenie:

This thesis locates historical discourses about music listening within the field of sound studies. Thus, the first three chapters illuminate the contiguities between sound studies and the so-called “sensory turn” introduced in the humanities and social sciences in the 1980s. An important theoretical premise of the research is the historicity of folk and expert notions that are normally employed in describing the structuring of the human psyche, like “sensation” and “perception”, which are related to the distinction between “to hear” and “to listen”. Chapters 1 and 2 addresses the historical development of the notion of “cultural construction of the senses”, which has been predominant among sensory scholars; they trace the emergence of the anthropology of the senses and the anthropology of the emotions, discussing also some critical approaches influenced by phenomenology and the anthropology of the body. The narration stresses the importance of authors, notions and theoretical elaborations associated with audition. Chapter 3 reviews the historical emergence of an awareness of the historicity of the senses and emotions in Europe, starting from the contributions of the French Annales School. It also deals with theoretical and methodological problems related to the historiography of the senses and emotions, in particular with the difficulties in establishing a periodization. Chapters 4, 5 and 6 form the historical core of the thesis, which zooms in on modern times, from the 15th century to the second half of the 19th century, that is until the publication of Helmholtz’s Die Lehre von den Tonempfindungen als physiologische Grundlage für die Theorie der Musik (1863). These chapters try to build a bridge between the history of aesthetics and the history of science by combining different thematic threads: the history of anatomical and physiological research into the ear and audition, the history of acoustics and the archaeology of audio technologies, and historical discourses on music listening. Chapter 4 presents the main disciplines that have historically dealt with hearing: physics music, rhetoric, medicine and physiology, psychology, and the convergence of electroacoustics, electrophysiology and psychoacoustics in 20th-century hearing science. It provides a short introduction to their history and the specificity of their approaches to hearing, stressing their connections to music and pointing at problems in the historicization of audition. While the chapter initially considers ancient and medieval notions of hearing and the senses in relation to music, it focuses mainly on early modern discourses on music and audition, including advances in anatomical and physiological knowledge, the relationship between rhetoric and music in Renaissance humanism, and the key role of music and the study of the senses in the establishment of the experimental programme of the so-called “Scientific Revolution”. The chapter offers a glimpse of aesthetic and scientific discourses on the senses, passions, sound, hearing and music until the end of the 17th century, when Sauveur proposed the foundation of acoustics. Chapter 5 deals with the 18th-century emergence of the concept of sensibility, with had roots both in Locke’s empiricism and in physiological research on muscle and nerve irritability, but ultimately stressed the connection between the senses and aesthetic and moral sentiments. It reviews important works of the French philosophes (Condillac, Diderot, Rousseau) on the differentiation and education of the senses, the sense of hearing and music aesthetics, as well as Rameau’s theory of harmony within the context of the mathematical development of acoustics in the 18th century. It also reviews some influential works on music aesthetics, and traces the transformation of musical taste and listening attitudes that took place in France and Germany towards the end of the 18th century, when hearing was increasingly defined as an “inner sense” and the notion of musical connoisseurs (Kenner) was formed. Chapter 6 briefly tackles on the acoustic research of Chladni and reports on the 19th-century development of new scientific instruments, including new musical instruments, which contributed to the refinement of scientific practices related to the measuring and evaluation of audition. This happened in parallel with the institutionalization of otology as a medical speciality, in the second half of the century, which is also narrated. The chapter then turns to sensory physiology and the pioneering work of Helmholtz, who developed physiological acoustics. His concern with delimiting the fields of aesthetics and science is presented here side by side with Hanslick’s efforts to define The Beautiful in Music, which would shape the notion of “absolute music”. The thesis closes with a narration of the reshaping of sensation by the new experimental psychology, pointing thus towards the beginnings of the psychology of music.
Aquesta tesi situa els discursos sobre la història de l’escolta musical en el context del camp, relativament recent, dels estudis de so (sound studies). Els tres primers capítols es proposen il·luminar la contigüitat entre els estudis de so i l’anomenat “gir sensorial” (sensory turn), que es va introduir en les ciències humanes i socials a partir dels anys 80. La investigació parteix de la historicitat de les nocions que fem servir habitualment per descriure l’estructura de la psique humana; nocions utilitzades per estudiosos i no estudiosos, com ara “sensació” i “percepció”, que sovint s’invoquen per explicar la diferència entre “sentir” i “escoltar”. Els capítols 1 i 2 s’ocupen del desenvolupament històric de la noció de “construcció cultural dels sentits”, que ha estat tan important dins del “gir sensorial”, i en aquest context expliquen l’emergència de l’antropologia dels sentits i les emocions, fent referència també a les crítiques formulades des de l’antropologia del cos i la fenomenologia. La narrativa d’aquests capítols subratlla el paper dins d’aquest procés històric d’autors, nocions i elaboracions teòriques relacionades amb l’audició i formulades des d’una comprensió d’aquesta. El capítol 3 repassa l’aparició en la història europea d’una consciència de la historicitat dels sentits i les emocions, a partir sobretot de les aportacions de l’escola francesa dels Annales. Tracta també alguns problemes teòrics i metodològics que planteja la historiografia dels sentits i les emocions, en especial les dificultats per establir-ne una periodització, també en el cas de l’audició. Els capítols 4, 5 i 6 formen el nucli històric de la tesi, que se centra sobretot en la modernitat, des del segle XV fins a la segona meitat del XIX, és a dir, fins a la publicació de l’obra de Helmholtz Die Lehre von den Tonempfindungen als physiologische Grundlage für die Theorie der Musik (1863), un text clau en la història de l’acústica i la fisiologia, que va posar també en qüestió la relació entre l’aproximació científica i estètica a la música i l’audició. Aquests tres capítols volen connectar la història de l’estètica i la història de la ciència combinant diferents línies temàtiques: la història de la investigació anatòmica i fisiològica sobre l’oïda i l’audició, la història de l’acústica i l’arqueologia de les tecnologies auditives, i els discursos històrics, en clau estètica, sobre l’escolta musical.

Los capítulos 1 y 2 se ocupan del desarrollo histórico de la noción de “construcción cultural de los sentidos”, que tan importante ha sido dentro del “giro sensorial”, y en este contexto explican la emergencia de la antropología de los sentidos y las emociones, haciendo referencia también a las críticas formuladas desde la antropología del cuerpo y la fenomenología. La narrativa de estos capítulos subraya el papel dentro de este proceso histórico de autores, nociones y elaboraciones teóricas relacionadas con la audición y formuladas desde una comprensión de la misma. El capítulo 3 repasa la aparición en la historia europea de una conciencia de la historicidad de los sentidos y las emociones, a partir sobre todo de las aportaciones de la escuela francesa de los Annales. Trata también algunos problemas teóricos y metodológicos que plantea la historiografía de los sentidos y las emociones, en especial las dificultades para establecer una periodización, también en el caso de la audición.

Estos tres capítulos pretenden conectar la historia de la estética y la historia de la ciencia combinando diferentes líneas temáticas: la historia de la investigación anatómica y fisiológica sobre el oído y la audición, la historia de la acústica y la arqueología de las tecnologías auditivas, y los discursos históricos, en clave estética, sobre la escucha musical.

Streszczenie:

Drinking water infrastructure functions to provide a service to meet customer demands and health requirements. Pipe repairs are one of the biggest challenges of ageing water infrastructure in the UK and world wide. Pressure transients resulting from sudden interruptions of the movement of the water can be caused by routine value operations. In a single pipeline one extreme event can burst a pipe. However the occurrences and impact of pressure transients in operational water distribution systems were not currently fully understood. This research developed new insights and understanding of pressure transient occurrences and their contribution to observed pipe repair rates. A large scale field monitoring program, including deploying and managing high-speed (100 Hz) instrumentation for 11 months, was designed and implemented to cover 67 district metered areas (DMA) subdivided into 79 pressure zones. In total 144 locations were monitored. The data was analysed using a novel method, termed transient fingerprint. This allowed the identification of discrete pressure transients and their three fundamental components (magnitude, duration and numbers of occurrences) leading to a quantitative interpretation of pressure transients. Evolutionary polynomial regression modelling was used to assess the impact of directly measured pressure transient data in context with static pressure, age, diameter and soil variables on 64 cast iron pipes. The analysis suggested that high magnitude, short duration repeatedly occurring pressure transients can have an adverse effect on the pipes. The extrapolation of pressure transient analysis into 7978 cast iron pipes showed inconclusive results suggesting that more accurate pressure transient data is required for each pipe in the network. Additional analysis carried out on 25 asbestos cement pipes, with actual measurements of pressure transients for each pipe, confirmed an adverse effect of pressure transient on water network observed in cast iron pipes. This research has provided an understanding of the occurrence of pressure transients that has implications on pipe management strategies. Mitigation techniques to locate pressure transient sources based on the project outcomes could be utilised to better manage distribution systems and ultimately reduce future pipe replacements and associated costs.

Product labeling is increasingly used as a tool to differentiate products with public and private benefits that cannot be readily evaluated by a consumer at the time of purchase. Our research investigates how a labeling program may be applied in the sale of ornamental plants to address two key issues; plant disease and irrigation water use. A choice modeling survey was utilized to estimate consumersâ willingness to pay a premium for six ornamental plants with disease-free and/or water conservation certification labels. The results of the mixed logit models show consumers are willing to pay a premium for plants certified as disease-free and/or produced with water conservation practices. The results strongly suggest producers can recoup some of the costs of implementing water conservation measures such as water recycling and disease control measures amid regulatory and drought concerns. Our research also investigated consumersâ preferences for multiple third party certifying authorities and whether preferences for the labels varied among consumers. The results showed ornamental plant consumers did not reveal a preference for a particular certifying authority. The results are mixed as to whether willingness to pay for the labels varies among respondents. We show willingness to pay does vary among respondents for three of the plant models indicating preference heterogeneity.

This manuscript provides an understanding of water conservation related innovations in green buildings, both in terms of what is being selected in design phase and how professionals perceive their experiences with these innovations. The innovations examined include toilets, showers, sinks, plumbing, water heating, appliances, alternative water sources, landscaping, performance monitoring, and user education. It contains a literature review of unanticipated consequences associated with these innovations, and creates a framework for categorizing these based on a synthesis of the literature of unanticipated consequences. A review of certification documents from the Leadership in Energy and Environmental Design (LEED) rating system identifies what landscaping, toilet, and shower innovations are most commonly designed for in LEED certified buildings. These data are also used to identify differences in innovation selection across climate regimes. An internet survey of green building professionals provides a picture of satisfaction with these innovations in practice. It also gives examples of these experiences so that future users can take advantage or take caution as necessary.

This paper discusses the issue of depersonalization and the subjective need for objectification and provides a means of understanding and developing a possible solution. Through the basic observation of an overlap between Behavioral Genetics, Neuroscience, Philosophy, Psychology, Physiognomy, the visual language and the artistic practice, one can begin to take note of the affects of our environments on an individualistic level. Through creative practice and the use of the visual language, one may develop an individualistic form of therapy. In recent years we have drifted away from the science of visual language and the basic aesthetic experience. The visual language and the basic aesthetic experience allow the depersonalized individual to engage in conversation and observation through an object of the visual language to the biological inner self as person. Through this conversation one may find comfort in the acknowledgment of the biological inner self as person from the other as person in hopes to subdue the subjective need for objectification. One may also gain a better understanding of the individualistic correlation between one's environment and one's biological inner self as person.

In 1987 Ntombikayise Priscilla Kubheka was abducted, tortured, killed and her body dumped by apartheid security police. She was an uMkhonto WeSizwe (MK), the armed wing of the African National Congress (ANC), commander based in Durban and was in charge of weaponry storage and organised safe houses for those returning from exile. Amnesty applications and perpetrator testimony given at the Truth and Reconciliation Commission’s (TRC) amnesty hearings alleged that Kubheka had died, while being interrogated, from a heart attack. The perpetrators claimed the heart attack was possibly as a result of Kubheka being overweight. In 1997 the Truth and Reconciliation Commission (TRC) exhumed skeletal remains and items of clothing, including a floral dress, from a pauper grave in Charlottedale cemetery, Groutville. The exhumed skull indicated a bullet wound. The post-mortem and numerous forensic examinations confirmed the identification of the skeletal remains to be those of Kubheka. The forensic examinations of the items of clothing confirmed the findings of the skeletal examinations in establishing identification. These forensic examinations and its findings contested testimony given by the perpetrators. Through the TRC investigations and its findings, a question of what it may mean to re-humanise the once missing emerges. This mini-thesis underscores a notion of re-humanisation through the work of the TRC in its investigation into the enforced disappearance of Kubheka. It suggests that figuring Kubheka through a notion of re-humanisation in the context of the TRC requires one to understand both de-humanisation and re-humanisation and the ways in which gender complicates these understandings. It does so by examining testimonies, t he exhumation, the forensic examinations, the emergence of a forensic aesthetic and the productions of biographies and forensic memory to understand how these might be processes and strategies of re-humanisation. This mini-thesis then is a forensic history that navigates a politics of the dead by examining the figuring of Kubheka through various fields and in various forums. In so doing, the argument presented in what follows is that the notion of re-humanisation is an inherently unstable one but at its core is a politics of the dead that misses gender it its figuring of the human.

Streszczenie:

Headwater catchments play a large role in the storage and release of water and chemical constituents, thereby influencing downstream flows and water quality. Recent advances in water quality monitoring technologies have created an opportunity to better assess water chemistry variation by using high temporal resolution, in situ sensors. However, despite these new technologies, there have been limited studies on installation approaches and their effects on sensor measurements. Accurate in situ monitoring is particularly important to capture catchment disturbance effects that may be highly dynamic over time (e.g., following storms) or limited in duration. For example, prescribed fire is a commonly applied forest management tool, but there remain questions regarding how this disturbance affects catchment soils and resultant stream water chemistry. Effective assessment of prescribed fire thus requires coupled monitoring of both soil properties and water chemistry. In this thesis, I addressed two linked objectives: i) assess the effects of commonly used protective housings on in situ sensor measurements (Chapter 2) and ii) evaluate prescribed burn effects in a southwestern Virginia, USA headwater catchment (Chapter 3). In Chapter 2, I compared four different housing types (mesh, screen, holes, and open) using in situ specific conductance measurements over time and from salt tracer injections for discharge estimates. This study demonstrated substantial effects from some of the housing types evaluated, where flow resistance reduced water exchange between stream water and water in contact with the sensor. From these findings, I suggest that in situ water quality sensors should be deployed in housing types with large openings perpendicular to flow. In Chapter 3, I assessed prescribed fire effects on soil properties (particle size, aggregate stability, and chemistry), stream discharge, and fine-scale water chemistry dynamics. Findings demonstrated some significant differences following fire in soil properties (e.g., overall decrease in aggregate stability, general decreases in total carbon and nitrogen of mineral soils), water quality (e.g., increased levels of DOC, turbidity, and nitrate) and discharge (increases in stage and flow). While these changes were statistically significant, differences in parameters before and after fire were generally small. Future work should examine if these effects persist through time, and whether the minor level of disturbance observed in this study results in any negative environmental impacts.

Headwater catchments (where precipitation first becomes streamflow) provide important aquatic habitat and regulate downstream water flows and chemistry. Recent advances in water quality monitoring technologies have created an opportunity to better assess water chemistry variability by using high frequency, submerged water quality sensors. However, these new technologies present new, unique challenges, such as measurement errors that may be induced by different installation methodologies. Accurate measurements are particularly important to evaluate how changes in catchment conditions (e.g., soils, vegetation) impact local and downstream water quality. For example, prescribed fire is a commonly used forest management tool, but questions remain about how it affects catchment soils and headwater stream chemistry. Consequently, understanding the effects of this and other catchment disturbances requires coupled monitoring of both soil properties and water quality. In this thesis, I addressed two objectives: i) assess the effects of commonly used protective housings on water quality sensor measurements (Chapter 2) and ii) evaluate prescribed burn effects in a southwestern Virginia, USA headwater catchment (Chapter 3). In Chapter 2, I demonstrated substantial effects from some of the housings evaluated and suggest that water quality sensors should be deployed in housing types with large openings perpendicular to flow. In Chapter 3, I demonstrated some significant effects of prescribed fire on soil properties (e.g. overall decrease in soil stability, general decreases in total carbon and nitrogen of mineral soils), water quality (e.g., increased levels of dissolved organic matter, turbidity, and nitrate) and flow (increases in stream water levels and flow). While these changes were statistically significant, differences in parameters before and after fire were generally small. Future work should examine if these effects persist through time, and whether this minor level of disturbance causes any negative environmental impacts.
