Dissertations / Theses on the topic 'Riverine landscape'

The Mekong River, an important transnational river in Southeast Asia, passes through six counties including China, Myanmar, Laos, Thailand, Cambodia and Vietnam. About 70 million people live in the Mekong Basin, and the basin provides many resources of people to make a living, and help to sustain the daily life routines of local community. The development of mainstream dams on the Mekong River is a potential major trans-boundary geopolitical issue for the Mekong countries, placing at risk millions of people who are closely linked to the Mekong and the resource it supports. The riverbank gardens and forests are going to be inundated, facing the situation of waterfront change and the land use competition, thus communities are under threats of food security and livelihood. This project is going to explore ways to sustain food security and to enhance the livelihood of local community, to adopt the potential changes raised by the Mekong dams as an opportunity rather than constraints, to improve the food security and enhance the benefit to local communities in terms of their livelihood by taking advantage of the water change to reorganize the riverside community, provide them space and guide the productive activities of local villagers, thus to increase the environmental and social benefit of the whole river system in a regional scale of the Mekong. Through this project a balance will be maintained in terms of the performance of river system and the livelihoods for local community.

Rivers around the world are under increasing pressure from a variety of human activities. Effective management of riverine landscapes requires an ecosystem approach and one that recognises the complex interactions between their physical, chemical and biological components. Perceptions of pattern and process are central to our understanding of riverine landscapes. Pattern and process operate over multiple scales to produce heterogeneous mosaics of landscape patches that change over time. Hierarchical patch dynamics provides a useful approach to unravel pattern and process at multiple scales in riverine landscapes. This thesis adopts a hierarchical patch dynamics approach to investigate floodplain sediment and nutrient dynamics within the Barwon-Darling River in South Eastern Australia. The flow regime of the Barwon-Darling River is highly variable. As a result, it has a complex channel cross section featuring inset-floodplain surfaces that occur at multiple elevations within the channel trough. These surfaces formed the focus of this study. The texture of inset- floodplain surface sediments displays a patchy spatial distribution and one that did not reflect lateral or longitudinal gradients within this floodplain landscape. Rather a sediment textural patch mosaic was identified. Nutrient concentrations associated with the surface sediments of the inset-floodplains were also shown to vary significantly resulting in a nutrient patch mosaic. This spatial nutrient mosaic was enhanced by factors including the surface elevation of the floodplain surface. Sediment and nutrient exchange between the river channel and inset-floodplain surfaces was measured during several flows in 2001, 2002 and 2005. Pin and sediment trap data showed that significant quantities of sediment were exchanged between the river channel and floodplain surfaces during inundation with both cut and fill processes occurring. Patterns in sediment exchange appear to be related to local sediment supply and seasonal sediment exhaustion, rather than the top down geomorphic constraints considered. These material exchanges resulted in a change to the spatial configuration of the sediment textural patch mosaic. Distinct new sediment textural patches were created following inundation, while other patches were lost post inundation and other patches changed sediment textural character to move into pre-existing patches. Thus a truly dynamic sediment textural mosaic exists within this floodplain landscape. Nutrient concentrations associated with floodplain sediments also changed over time. While nutrient concentrations increased after the December 2001 flow event, they generally decreased after the March 2002 event, highlighting their dynamic nature over time. The spatial distribution of nutrient concentrations also varied over time, with a 40 percent change to the nutrient mosaic as a result of the March 2002 flow event. In addition to the influence of the changing physical template (sediment texture mosaic), nutrient concentrations were shown to be influenced by rainfall processes on non flooded surfaces, and also a number of top-down constraints and bottom-up influences operating over multiple spatial scales. Overall, the inset-floodplains studied in this thesis acted primarily as sediment and nutrient sinks, and were a source for dissolved nutrients. Nutrient exchange was associated with the exchange of sediments in this riverine landscape, over both inter-flow and decadal timescales. It was demonstrated that water resource development within the catchment reduced the number, magnitude and duration of flow events down the Barwon-Darling River and as a result reductions in the exchange of sediment, associated and dissolved nutrients between inset-floodplains and the main river channel were calculated. The greatest reductions were with the release of dissolved nutrients (42-25 percent) and the exchange of sediment and associated nutrients from high level surfaces (43 percent). Effective conservation and management of riverine ecosystems must occur at the correct scale. This study identified potential nutrient hotspots at several scales in the Barwon-Darling floodplain landscape that could be targeted by management. The low predictability of the location of nutrient hotspots at the inset-floodplain scale over time means that environmental flows should be targeted at high level surfaces (<25 000 MLD-1) that provide long term sources of carbon to the river channel. Conserving flows of this magnitude will also reinstate flow variability, an important facet of the Barwon-Darling River?s hydrology that has been changed by water resource development. The research presented in this thesis highlights the importance of not only considering pattern and process at multiple scales, but also the way in which these processes influence landscape patterns over time, leading to the identification of the appropriate scales that can best be targeted for the conservation of these systems.

Riverine landscapes are complex. More than just a single channel, they comprise a shifting mosaic of hydrogeomorphic patches with varying physical and biological characteristics. These patches are connected by water during flows of varying magnitude and frequency, at a range of spatial and temporal scales. Combined, landscape complexity and hydrological connectivity create biological diversity that in turn maintains the productivity, ecological function, and resilience of these systems. This thesis investigates the ecological importance of spatial heterogeneity and temporal hydrological connectivity in a dryland floodplain river landscape. It focuses on anabranch channels, and uses major carbon sources in these and adjacent landscape patches as indicators of ecological pattern and process. A conceptual model was proposed, describing the potential effects upon the distribution and availability of major carbon sources of: a) a spatial mosaic of hydrogeomorphic patches in the landscape (e.g. anabranches, river channel, and wider floodplain); and b) four primary temporal phases of hydrological connection during flow pulses (disconnection, partial connection, complete connection, and draining). This was then tested by data collected over a three year period from a 16 km reach of the lower Macintyre River (NSW/QLD Australia). Results were examined at multiple spatial scales (patch scale � river channel vs. anabranches vs. floodplain; between individual anabranches; and within anabranches � entry, middle and exit sites). The data indicate that spatial heterogeneity in the lower Macintyre River landscape significantly influences ecological pattern. Carbon quantity was greater in anabranch channels compared to adjacent river channel patches, but not compared to the floodplain; while carbon quality was greater in anabranch channels compared to both adjacent river channel and floodplain patches. Stable isotope analysis indicated that carbon sources that were predominantly found in anabranch channels supported both anabranch and river organisms during a winter disconnection phase. Other carbon sources found in the main river channel and the wider floodplain appeared to play a comparatively minimal role in the food web. Different phases of hydrological connection between anabranch channels and the main river channel were associated with differences in the availability of carbon sources. In the river channel, draining of water from anabranches (the draining phase) was associated with relatively high concentrations of dissolved organic carbon (DOC) and low concentrations of phytoplankton. Conversely, the disconnection phase was associated with relatively low concentrations of DOC and high concentrations of phytoplankton in the river channel. In anabranch channels and their waterbodies, the disconnection and draining phases were associated with high concentrations of both DOC and phytoplankton. Concentrations of these carbon sources were lowest in anabranches during the partial and complete connection phases. Different hydrological connection phases were also associated with changes in trophic status in the aquatic components of the landscape. On the riverbanks, relatively low rates of benthic production and respiration during the complete connection phase were associated with heterotrophy. The remaining phases appeared to be autotrophic. Benthic production on riverbanks was greatest during the disconnection phase, and respiration was greatest during the partial connection phase. In the anabranch channels, rates of production and respiration were similar during the disconnection phase, and were associated with heterotrophy in the anabranch waterbodies. The remaining phases appeared to be autotrophic. Respiration was greatest in anabranches during the disconnection phase, and production was greatest during the draining phase. Both production and respiration were lowest during complete connection. These differences and changes varied according to the landscape patch examined. At a landscape scale, anabranch channels act as both sinks and suppliers of carbon. High rates of sediment deposition facilitate their role as sinks for sediment-associated carbon and other particulate, refractory carbon sources. Simultaneously, anabranch channels supply aquatic carbon sources from their waterbodies, as well as via processes such as inundation-stimulated release of DOC from surface sediments. Modelled data indicated that water resource development reduces the frequency and duration of connection between anabranch channels and the main river channel. This loss of landscape complexity via loss of connectivity with anabranches has the potential to reduce the total availability of carbon sources to the ecosystem, as demonstrated by a modelled 13% reduction in potential dissolved organic carbon release from anabranch sediments. This thesis has demonstrated the importance of spatial heterogeneity in riverine landscapes, by documenting its association with variability in the distribution and quality of primary energy sources for the ecosystem. It has shown that this variability is augmented by different phases of hydrological connectivity over time. Spatial heterogeneity and hydrological connectivity interact to increase the diversity and availability of ecological energy sources across the riverine landscape, at multiple spatial and temporal scales. This has positive implications for the resilience and sustainability of the system. Anabranch channels are particularly important facilitators of these effects in this dryland floodplain river system. Anabranch channels are �intermediate� in terms of spatial placement, temporal hydrological connection, and availability of carbon sources; of high value in terms of high-quality carbon sources; and relatively easy to target for management because of their defined commence-to-flow levels. Further research should be directed toward evaluating other ecological roles of anabranch channels in dryland rivers, thereby providing a more complete understanding of the importance of connectivity between these features and other patches. This knowledge would assist management of floodplain river landscapes at larger regional scales, including amelioration of the effects of water resource development.

In Taiwan, the river terrain is steep and the river course is sloppy, adding to the soil is unstable and the raining season is concentrating, There fore the first step of the river renovation is to construct the flood protection facility. Recently, because of the international trends, the economic development, the increasing of general income, Taiwanese put much athenaeum to pursuit the better quantity and much quantity of living space. To fulfill this expectation, the accessibility to and recreation function of water appear on the riverbank’s. 　　 　　Furthermore, in recent year, the transformation of economic structure and the impact of joining WTO result in new challenge for agricultural production and marketing, Thus the government elaborates on the reconstructs if countryside with expecting to redefine Taiwan’s countryside the strategy of recreational agriculture. 　　 　　Moreover, various units of community development, Vigorly participate the program, incorporating local characters and finding related financial supports, Thus the improvement of countryside’s riverbank become essential for community development. 　　 　　This research takes the sustainability of Ecology as the main elaboration foundation, assign Jiayi County Chu-chi township Yi-ren bridge section river bank as research object. By means of data collections, the long-term ecological monitor, observation and interview, the research is separated from the metropolitan waterfront thinking’s and set up sustainable development strategies and future planning standards for the countryside’s riverbanks in Taiwan. 　　 　　Under the concept of landscape ecology’s structure, function and variation, the research inspects the implementation process of the landscape plan, the research is covers the plants of 69 branches and 202 kinds, most of which are “Gramineae” and the “Asteraceae”. Further discussing of the old tree retention, the sluing discovers that the construction has created the landscape fragmented. By means of analyzing the green construction, obviously the eco-technology method is comparatively more efficient in preserving greenery biodiversity and water, thus deserving much encouragement. 　　 　　The research finds 15 branches and 19 kinds of different species in bird monitor. Most of them are resident birds, which include summer specie. “domestic swallow” and winter species “Motaglla cinerea”and “Domestic sparrow”. The intensity of richness shows passivity along with the stability of matrix. Under the planning stressed on green preservation and ecological-pond creation, the designated site still maintains the richness of bird species. Moreover , under the micro-viewpoint of bird monitor, the designated site testify the fragmented shape theory. The research finds 6 branches and 10 kinds of attests fish species. The appearance of “Acrossocheilus paradoxus” the light pollution level of local water quality. On the other hand, the fix work of river-bed and embankment restoration night result in the obvious reduction of various species. 　　 　　The landscape planning is intended for the eco-technology method, and tries to link local culture sector with natural ecology. However, a lack of discussion from the local people. result in recognition differences in following maintain and issues. In terms of site facilities, the project still pays much attention to recreation faction. Which needs much communication with sustainable management. By function improvements of eco-technology. Method deserves much praise.

In recent years, functions of park green space of Taiwan area have become more diverse and the use rate has become higher; however, the planning and design stage is not able to completely anticipate all the demands of the future and the park is often used out of rules or fails to meet nearby residents’ requirements and the residents make the device by themselves. These phenomena have caused great impact on the integral landscape of the park and its safe use. Besides, under the environment of promoting urban disaster prevention concept, the functions of disaster park have gradually aroused people’s attention. In addition, the concept of intelligence park has gradually formed. To combine the modern science and technology with recreation function, environmental monitoring, cloud management and other factors has become the condition shall be considered in the use design of the future parks. This design selects Huludun as the design base for the reason that this base does not a complete upper planning and design after the municipal government held the Flora Expo in 2018 and it is a waste for such a rare banding waterfront park in the city. Through investigating and analyzing the geographical position and surrounding environmental background, and coordinating relevant theories and literatures, this article locates the design direction of the multifunction and intelligence city park which integrates recreation, sightseeing and disaster prevention and other functions, and tries to build a city waterfront park which combines both utility function and sightseeing value in the auxiliary city center of resident and Taizhong City-Fengyuan.

This research is to explore the structure of people’s mind of Shi Gouzhen, Xiushui Township, Changhua County. To excavate such deep thoughts, the researcher invited five experts to accept interview relating to landscape image of both sides of Shi Gouzhen by laddering method for guidance. The questions include 1.thoughts and feelings. 2. The source of inspiration. 3. Reasons and explanations of like and unlike to selected scenic spots. By classifying and extracting constructs from the transcripts of interviewees, finally 24 landscape factors were gained. They were "artificial feel", "green nature", "Sense of order", "countryside Image", "design sense," "traditional," "particularity", "leisure space", "monotonous", "crushing sense", "harsh environment", "visual focus", "naturalness"," open nature ", "dangerousness ", "color", "simple nature ", "calmness","curve", "drape", "gently sloping", "climbing nature", "vitality", "comfort". Exploring fator analysis obtained five dimentions: "countryside living", "riparian terrain," "human order", "dangerous field", "unfeeling and exclusion". These indicators affect people in central Taiwan. Shi Gouzhen landscape on the Changhua County. In space planning, the study maintained "countryside Image" and "leisure space" were concrete landscape images and acquired practical approach by using multiple regression analysis. Shi Gouzhen is an important irrigation canal in agricultural rigion, Changhua plain. When leisure fashion comes, roles of existing agricultural facilities need to convert. The landscaping planning index offer the basis for the design development to landscape architects, and the research results would be a reference for landscape planning of Government and private sectors.

Landscape ecology is to analyze the landscape from the viewpoint of ecology. It mainly includes three features: structure, functionality and change. Geographically, the urban areas in Taiwan are closely related to rivers, which carry a large amount of sediment during the rainy seasons. Urbanization brings dirt and silt to the river, and causes flooding. So, our goal of maintenance is to improve the rivers. With the raising income, people expect a quiet and comfortable living environment that connects with the international trend of sustainable development. 　　The completeness of river green-way system and the connection to other ecosystem corridors are influenced by unsuitable river maintenance and flood control constructions. This research studied the whole urban waterfront planning, including river characteristics, case study of domestic and international waterfront revitalizations, environmental impact indices, and resident participation. The evaluation was divided into three main parts: 1. river corridors evaluation; 2. river environmental evaluation with preferred landscape corridor features and designs of the different river segments; and 3. environmental impact indices evaluation. The Water Park in Bajhang River was investigated and analyzed. Planning recommendations were made according to the results. Urban river flood prevention, water use, ecosystem, and recreation were combined with the idea of eco-friendly river maintenance and water accessibility to construct a harmonic, comfortable, and beautiful urban waterfront environment; in order to arouse the residents’ community sense and environmental awareness; and to attain the goal of sustainable management.

Taiwan is an island which has the following characteristics: many rivers and high mountains, high temperature, heavy rain and flooding disasters. With these characteristics, many river banks have been constructed along the riverside for the reason of security. Until the year of 1996, the length of river bank in Taiwan is about 2,660,615 meters .Due to this fact, as well as for the security reason, how to utilize the special geological location of riverbank surrounded by water and mountain to create the function of landscape and entertainment has become especially meaningful.. Using Aieliau River as an example, this research applies the theory of three principles of landscape planning & design, scene-exploring, visitor survey and literature review to emerge theory and practice, and hopefully to result in contributing to the value of conference for future construction of riverbank parks.

Dissertação de Mestrado Integrado em Arquitetura apresentada à Faculdade de Ciências e Tecnologia
Nas últimas décadas tem-se verificado um grande crescimento populacional a nível global. Paralelamente a esse crescimento, tem-se observado uma crescente ocupação das áreas urbanas por parte da população e, dada essa preferência, este valor tende a aumentar. Aliado ao panorama suprarreferido apresenta-se o mau planeamento urbano, onde se tem sentido as sérias consequências das mudanças climáticas, tanto na perda da biodiversidade como dos recursos naturais, e na diminuição, dispersão e poluição dos espaços verdes. Simultaneamente a todos estes acontecimentos, ocorre a degradação e diminuição da paisagem urbana que ameaça a qualidade de vida da população. Neste contexto, os corredores verdes surgem como uma solução para uma estratégia de planeamento mais sustentável. Estes possuem a capacidade de gerir múltiplas funções, oferecendo e possibilitando a conservação do território tanto em áreas rurais como urbanas. Neste enquadramento, a presente dissertação integra um projeto para a cidade de Aveiro, tendo subjacente a valorização da qualidade paisagística dos corredores naturais inseridos no território. O projeto procura ainda, valorizar as estruturas ecológicas naturais que para além de serem elementos distintos e de identificação da cidade, são também elementos que podem diferenciar a forma como os espaços públicos podem ser vividos. Este pretende encontrar soluções para um equilíbrio ecológico, traduzido numa vivência harmoniosa entre o Homem e a Natureza, promovendo novas práticas de habitar que não só consigam coexistir em perfeita harmonia com o espaço natural, como também garantir o carácter rural que define o território. Desta forma, o projeto apresentado divide-se em três partes: uma intervenção urbana à escala do território que pretende, através dos corredores naturais da cidade, ligar o centro histórico de Aveiro com a periferia, amenizando o impacto negativo que a estrada nacional (EN 109) representa. Uma requalificação de um fragmento do território inserido numa ribeira com grande valor paisagístico. Por último, a introdução de novos programas e a criação de um conjunto habitacional com a intenção de densificar o território e proporcionar à população de Aveiro novas modos de habitar.
In the last decades, there has been a great population growth. At the same time, population density has been an increasing in urban areas and it doesn’t seem to be slowing down. In addition to the above-mentioned panorama, there is a poor urban planning, where the serious consequences of climate change have been felt, both in the loss of biodiversity and natural resources, and in the reduction, dispersion and pollution of green spaces. Simultaneously to all of this, the urban landscape is decreasing and deteriorating which threatens the population’s quality of life.Given this context, greenways appear as a solution for a more sustainable planning strategy. These have the ability to manage multiple functions, offering and enabling the conservation of the territory in both rural and urban areas. As such, this dissertation is part of a project for the city of Aveiro, which underlies the enhancement of the landscape quality of the natural greenways inserted in the territory. The project also seeks to enhance the natural ecological structures, which are elements of distinction and identity of the city, while differentiating the way public spaces can be experienced. It aims to find solutions for an ecological balance, translated into an harmonious experience between Man and Nature, promoting new living practices that not only manage to coexist in perfect harmony with the natural space, but also guaranteeing that the rural character that defines the territory is kept.The present project is divided into three parts: an urban intervention at the scale of the territory that intends, through the natural corridors of the city, to connect the historic center of Aveiro with the periphery, mitigating the negative impact that the national road (EN 109) represents. A requalification of a fragment of the territory inserted in a stream with great landscape value. Finally, the introduction of new programs and the creation of an housing complex with the intention of densifying the territory and providing the population of Aveiro with new ways of living.
