Abstract:
Hydrological tracers, commonly used for characterizing water flow paths and sources, do not often meet all the requirements of an ideal tracer. Trans-disciplinary approaches are advocated as the way forward to enlarge the number of tracers available for investigating hydrological processes. Since the 19th century, hydrological tracers have been increasingly used, particularly in underground areas. The tracer toolbox at hand includes a large variety of options, including fluorescent dyes, isotopes, salts or bacteriophages, with each tracer offering specific qualities and complementarities. While their potential for hydrological studies has been studied in karstic environments since the 1960s, bacteriophages remain insufficiently understood. According to the selection methodology used in this review, more than thirty experiments have been listed, involving in total around seventeen different bacteriophages. These have facilitated the investigation of groundwater, surface water (i.e., river, lake and marine water), wetland and wastewater hydrological processes. The tracing experiments have also highlighted the possible interaction between bacteriophages and the surrounding environments. Bacteriophages have successfully helped researchers to understand the water flow within watersheds. Certain advantages, such as the sensitivity of detection, the ease of producing high concentrations of bacteriophages to be injected, their specificity for a host and their non-pathogenicity for human and animal cells, make bacteriophages appreciable tracer candidates for tracing experiments. However, the adsorption process or environmental factors such as temperature, pH and UV light considerably impact the fate of bacteriophages, thereby leading to an attenuation of the phage signal. Considering both the flaws and the qualities of bacteriophages, their use as hydrological tracers requires new insight and further discussions regarding experimental tracing conditions.

Abstract:
AbstractTracer methods have been widely used in many fields of environmental and natural sciences, and also in human health sciences. In particular, tracers are used in the study of karst hydrogeology, typically focusing on phenomena such as sinkholes, sinking rivers and large karst springs. It is known that tracers have been used since antiquity. The aim of tracer tests has been to investigate underground flow paths, transport processes and water–rock interactions, and to get an insight into the functioning of a karst aquifer. In karst hydrogeology, tracer methods are the most important investigation tools beside conventional hydrological methods. In early times, tracer methods were applied only to investigate underground flow-paths. Later they were also used to elucidate transport processes associated with water flow, and today they are often the basis, together with detailed hydrological information, of groundwater protection investigations and aquifer modelling. Many substances (spores, microspheres, bacteriophages, salt tracers, fluorescent dyes, radioactive substances) have been investigated for their properties and potential usage in environmental investigations, in particular the often unknown and inaccessible underground systems of karst areas. A great number of analytical techniques is available. This includes instrumentation for laboratory applications and direct online, on-site or in-situ field measurements. Modern instruments have a high capability for data acquisition, storage and transmission in short intervals, as a basis for quantitative evaluation and modelling. This enables research on the hydrological and hydrochemical dynamics of aquifers and their response to different natural or anthropogenic impacts.

Abstract. Over 11 000 L of kerosene was deposited on the surface of Rabots glaciär on the Kebnekaise Massif, northern Sweden, following the crash of a Royal Norwegian Air Force aircraft in March 2012. An environmental monitoring programme was subsequently commissioned, including a series of dye tracing experiments during the 2013 melt season, conducted to investigate the transport of pollutants through the glacier hydrological system. This experimental set-up provided a basis from which we could gain new insight into the internal hydrological system of Rabots glaciär. Results of dye tracing experiments reveal a degree of homogeneity in the topology of the drainage system throughout July and August, with an increase in efficiency as the season progresses, as reflected by decreasing temporary storage and dispersivity. Early onset of melting likely led to formation of an efficient, discrete drainage system early in the melt season, subject to decreasing sinuosity and braiding as the season progressed. Four distinct meltwater flow regimes are identified to summarize the temporal and spatial evolution of the system. Analysis of turbidity-discharge hysteresis further supports the formation of discrete, efficient drainage, with clockwise diurnal hysteresis suggesting easy mobilization of readily available sediments in channels. Dye injection immediately downstream of the pollution source zone reveals prolonged storage of dye followed by fast, efficient release. Twinned with a low dye recovery, and supported by sporadic detection of hydrocarbons in the proglacial river, we suggest that meltwater, and thus pollutants in solution, may be released periodically through an efficient, and likely pressurized, hydrological system within the upper reaches of the glacier.

The scientific programme further included a series of dye tracing experiments during the 2013 melt season, conducted to investigate flow pathways for pollutants through the glacier hydrological system, and to gain new insight to the internal hydrological system of Rabots glaciär.

Twinned with a low dye recovery, and supported by sporadic detection of hydrocarbons in the proglacial river, we suggest that meltwater, and thus pollutants in solution, may be released periodically from this zone of the glacier hydrological system. The here identified dynamics of dye storage, dispersion and breakthrough indicate that the ultimate fate and permanence of pollutants in the glacier system is likely to be governed by storage of pollutants in the firn layer and ice mass, or within the internal hydrological system, where it may refreeze. This shows that future studies on the fate of hydrocarbons in pristine, glaciated mountain environments should address the extent to which pollutants in solution act like water molecules or whether they are more susceptible to, for example, refreezing into the surrounding ice, becoming stuck in micro-fractures and pore spaces, or sorption onto subglacial sediments.

Abstract:
The hydrological connectivity below the soil surface can influence the forest structure and function, especially soil and plant productivity. However, few studies have determined the changes in the hydrological connectivity below the soil surface with increasing soil depth and have quantified the effects of root systems on the hydrological connectivity in forest ecosystems. In this study, we evaluated the index of the hydrological connectivity (IHC) below the soil surface using a field dye tracing method and compared the difference in the index of hydrological connectivity in two subtropical forest stands (i.e., pine trees [SS] and bamboo [ZL]). We analyzed the interactions between the parameters of root system architecture and the index of hydrological connectivity. Back propagation (BP) neural networks were used to quantify which parameter can contribute the most relative importance to the changes of the IHC. The results revealed that the maximum value of the index of hydrological connectivity occurs at the soil surface, and it exhibits a non-linear decreasing trend with increasing soil depth. The parameters of root system architecture (root length, root projected area, root surface area, root volume, and root biomass) were rich in the top soil layers (0–20 cm) in the two sites. Those parameters were positively correlated with the IHC and the root length had the largest positive influence on the hydrological connectivity. Furthermore, we found that root system architecture with different root diameters had different degrees of influence on the index of hydrological connectivity. The very fine root systems (0 < D < 1 mm) had the greatest effect on the hydrological connectivity (p < 0.01). The results of this study provide more information for the assessment of the hydrological connectivity below the soil surface and a better understanding of the effects of root systems in soil hydrology within the rhizosphere.

Abstract:
Abstract. Diatoms, microscopic single-celled algae, are present in almost all habitats containing water (e.g. streams, lakes, soil and rocks). In the terrestrial environment, their diversified species distributions are mainly controlled by physiographical factors and anthropic disturbances which makes them useful tracers in catchment hydrology. In their use as a tracer, diatoms are generally sampled in streams by means of an automated sampling method; as a result, many samples must be collected to cover a whole storm run-off event. As diatom analysis is labour-intensive, a trade-off has to be made between the number of sites and the number of samples per site. In an attempt to reduce this sampling effort, we explored the potential for the Phillips sampler, a time-integrated mass-flux sampler, to provide a representative sample of the diatom assemblage of a whole storm run-off event. We addressed this by comparing the diatom community composition of the Phillips sampler to the composite community collected by automatic samplers for three events. Non-metric multidimensional scaling (NMDS) showed that, based on the species composition, (1) all three events could be separated from each other, (2) the Phillips sampler was able to sample representative communities for two events and (3) significantly different communities were only collected for the third event. These observations were generally confirmed by analysis of similarity (ANOSIM), permutational multivariate analysis of variance (PERMANOVA), and the comparison of species relative abundances and community-derived indices. However, sediment data from the third event, which was sampled with automatic samplers, showed a large amount of noise; therefore, we could not verify if the Phillips sampler sampled representative communities or not. Nevertheless, we believe that this sampler could not only be applied in hydrological tracing using terrestrial diatoms, but it might also be a useful tool in water quality assessment.

Abstract:
Hydrological tracer testing is an effective way to determine the law of recharge and the transport of groundwater. In karst collapse mine water treatment, the hydrological tracing test can determine information such as the runoff velocity and the pattern of underground runoff, so that targeted grouting becomes possible. In this paper, NaCl was used as a tracer, and the content of the tracer was determined by the chloride ion selective electrode method. The NaCl concentration–time curve was plotted, and we obtained a tracer test method that can determine the runoff of the karst quantificationally. The method can quantificationally obtain the groundwater transport velocity, runoff pattern, and connectivity. This combination of grouting rate, grouting pressure, and setting time realized the localized targeted grouting and achieved a significant water damage control effect.

Abstract:
Water is ubiquitous on our planet and constitutes a vital part of ecosystems. It supports the life of all beings on the earth while simultaneously evokes water-related issues such as water shortage, water contamination. As UN advocates, a globally shared blueprint for available clean water is depicted in Sustainable Development Goals (SDGs). However, there still exists a gap between current water management situations and our sustainable goals Modelling based on Hydro-Meteorological Data provides a way to understand regional hydrological processes and monitor environmental chemistry changes, especially for anthropogenic pollution. Furthermore, hydrological models make it possible to predict changes in water quantity and quality, under the context of climate change. The study area of this project is located in the Kringlan catchment, Norrström basins, occupying an area of 54.5 km2. The local discharges merge into Rastälven river and flow to the east, eventually discharging into the Baltic Sea. This project builds up a water balance model based on the meteorological data in the time frame from 2011 to 2012. The water balance model is calibrated to accurately simulate realistic hydrological components interactions, during each process, various parameters have been tested and adjusted to improve model robustness. Meanwhile, the project tries to strike a balance between the complexity of the model and amount of time it takes to run the model. The calibrated model is also validated to ensure model performance using statistical analysis. Additionally, a particle tracking model for the saturated zone is developed on the basis of the water balance model. Chloride is chosen as the trace element due to its feature of unreactive in ecological systems. The model results could also provide a value to groundwater age estimation. Suggested by previous researches targeting the area, leakage from vegetation and forest soil in this catchment have contributed to imbalances in local Cl- budgets. An internal source of chloride from soil leaching is specified in the model at the same time with an external source from stream discharge. The coupled modelling through the application of MIKE SHE software and calibration process help us to understand dynamic processes of hydrological modelling and chloride particle transport in the Kringlan catchment. A future improvement to consider is extending the current model boundary to a larger area and introducing more reference data. It is also possible to establish a fully integrated solute transport model to investigate Chloride transport in the catchment.
Vatten ersätter en viktig del av ekosystemet men det framkallar vattenrelaterade problem som vattenbrist och vattenförorening samtidigt. Emellertid finns det fortfarande ett gap mellan nuvarande vattenhanteringssituationer och våra hållbara mål. Modellering baserad på meteorologiska data erbjuder en möjlighet att förstå regionala hydrologiska processer och övervaka förändringar av miljömässiga kemikalier, särskilt för antropogena föroreningar. Dessutom finns det en hög potential för att förutse förändringar i vattenmängd och kvalitet med hydrologiska modeller, i samband med klimatförändringar. Studieområdet ligger i Kringlans upptagningsområde som ett av Norrström basins, med en yta på 54,5 km2. De lokala utsläppen sammanfogas i Rastälven och strömmar österut, så småningom mynnar i Östersjön. Detta projekt bygger upp en vattenbalansmodell baserad på meteorologiska data inom tidsramen från 2011 till 2012. Vattenbalansmodellen är kalibrerad för att exakt simulera realistiska hydrologiska komponentinteraktioner. För att förbättra modellens robusthet har olika parametrar testats och anpassats under varje process. Samtidigt försöker projektet att hitta en balans mellan modellens komplexitet och hur lång tid det tar att driva modellen. En partikelspårningsmodell för den mättade zonen har utvecklats med utgångspunkt i vattenbalansmodellen. Klorid används som spårämne eftersom det är inert i ekologiska system. Modellsresultaten kan också ge ett värde för grundvattenberäkningen. Tidigare undersökningar inriktade på området föreslår att läckage från vegetation och skogsmark i detta avrinningsområde har bidragit till obalanser i lokala Cl- budgetar. Med hjälp av MIKE SHE modellen har vi undersökt dynamisk process för hydrologisk modellering och kloridpartikelspårning i Kringlan avrinningsområde. Vad som kan gör i framtiden är att förlänga den nuvarande modellgränsen till ett större område med mer referensdata. Det är också möjligt att upprätta en fullständigt integrerad lösningsmodell för att undersöka kloridtransporter i ett avrinningsområde.

Black Box trees (Eucalyptus largiflorens) across the Murray-Darling Basin are in critical condition due to high groundwater salinity and infrequent natural flooding. Geochemical tracers such as radiogenic strontium (87Sr/86Sr), oxygen-18 (𝛿𝛿18O) and deuterium (𝛿𝛿D) are considered useful in the understanding of catchment hydrology and plant water use, and in this study, 87Sr/86Sr, 𝛿𝛿18O and 𝛿𝛿D isotopes were used accordingly to better comprehend local hydrology and water use behaviour patterns of Black Box trees on the Calperum Floodplain, South Australia. Investigations were achieved by sampling and analysing local surface waters (Lake Merreti, Lake Clover, and River Murray), groundwater, soils (1.5 m depth) and plant material (stem water, and leaves) from two separate sites, north (Site 1) and south (Site 4). Considering the local hydrology, Lake Clover was composed of evaporated rainwater, while Lake Merreti was a relative mix of both evaporated rainwater and river water. Additionally, local rainfall sources appeared to vary overtime. Furthermore, groundwater showed no close relationship with rain water suggesting an alternative recharge source such as river water or remnant paleo-water. In terms of water use, linear mixing models using soil 87Sr/86Sr, leaf 87Sr/86Sr and stem water 𝛿𝛿18O inputs showed that Site 1 trees, on average, were predominately using rainwater (77%, 77% & 67%), while Site 4 trees used both rainwater (16%, 32% & 42%) and saline groundwater (70%, 62% & 58%), regardless of nearby lakes and streams. These findings have implications for future monitoring, and the management of outer floodplain Black Box populations that are unable to receive natural flooding inundation.

In order to understand environmental parameters and hydrological influence on eDNA concentration, this study conducted eDNA technology to investigate Channa micropeltes, an invasive species, eDNA concentration. Our study areas include TsengWen Reservoir, NanHua Reservoir and HouJue River. We sampled Channa micropeltes eDNA concentration in all study areas besides TsengWen Reservoir where we investigated different water depth based on two different hydrological conditions. We discovered eDNA concentration in TsengWen Reservoir demonstrated the higest value in 10 m water depth, and lowest value in surface water. The eDNA concentration decreased and distribution was uniformed after rainfall caused runoff disturbing water in the reservoir. In addition, the eDNA concentration distributed higher value at middle section in NanHua Reservoir and downstream of HouJue River.

Rainfall-induced surface runoff combined with soil erosion is one of the most important surface hydrological processes and its harmful impact on the environment and communities has been studied for decades. Understanding and modelling surface hydrological processes is vital for engineers, scientists, and policymakers to be able to develop water management and soil conservation strategies. Therefore, mathematical models that can predict the impact of surface hydrological processes on the environment require good quality measured hydrological data. Cost-effective innovative techniques are needed to obtain the good quality hydrological data from field and laboratory experiments. Furthermore, the presence of rock fragments in soils is a major soil property. Identifying the relationship between the rock fragments and surface-subsurface hydrological processes is a major challenge but one that is essential for the development of soil water conservation measures for the rock-fragment abundant soils. The present thesis focuses on two main objectives. The first is to improve understanding of the impact rock fragments have on surface-subsurface hydrological processes at plot and hillslope catchment scale. The second is concerned with the development of innovative measuring techniques and mathematical models related to surface hydrological processes. The research for the first objective started by comparing the influence of soil surface geometry and different distributions of surface rock fragment cover on runoff and soil loss under controlled laboratory conditions. Three different patterns of a constant surface rock fragment cover were tested for a single rainfall intensity event on converging and diverging plane soil surfaces at constant hillslope gradient. The study suggested that the understudied soil surface geometries had more influence on soil erosion than different distribution patterns of a specific percentage of rock fragment surface cover. The next study compared the simulated soil water response of stony soils with measured catchment runoff at hillslope scale. Rainfall-induced soil water response was simulated at three mountain catchment sites using the Hydrus-2D single porosity model. The soils at these sites had 10-65% stoniness. Soil hydraulic parameters employed in the numerical simulations, i.e. the saturated hydraulic conductivity and parameters of the soil water retention curves, were obtained by the Representative Elementary Volume approach (REVa) and by the inverse modelling with Hydrus-1D model (IMa). Shapes of the simulated soil water outflow hydrographs were similar to the measured catchment runoff ones for about a half of rainfall events. Furthermore, soil hydraulic parameters derived by REVa produced more realistic shapes of soil water hydrographs than the IMa ones. The research for the second objective started by testing the capability of a new thermal tracer (cold oil droplets) to measure the velocities of shallow overland flows (<2 mm depth) using the infrared-based particle tracking velocimetry (PTV) technique under controlled laboratory conditions without rainfall. This new approach was compared with dye tracing and the conventional PTV technique (polystyrene beads as tracer and optical video camera) in a quasi-laminar flow regime. The results showed that the infrared-based and conventional PTV techniques estimated velocities were closer to mean velocities measured through volumetric discharge method than were those given by the dye tracing method. This research stressed the potential of the infrared-based PTV technique to estimate the velocities of shallow water bodies due to its tracer's prominent visibility and independence from lighting conditions. Lastly, a 1D physically-based overland flow model that uses cascade plane theory for the estimation of rainfall-induced surface runoff, infiltration and soil erosion on converging and diverging plane surfaces was developed. The model’s simulations were evaluated by the measured data collected under controlled laboratory conditions. Satisfactory results indicated that the model could help to improve the modelling techniques for overland flow and soil erosion on convergent and divergent plane surfaces.
O escoamento superficial e o transporte sólido, induzidos pela precipitação, são importantes processos hidrológicos estudados há décadas, sendo o seu impacto muitas vezes prejudicial no meio ambiente e nos aglomerados populacionais. Compreender e modelar os processos hidrológicos de superfície é vital para que engenheiros, cientistas e decisores políticos possam desenvolver estratégias de gestão de água e conservação do solo. É por isso que os modelos matemáticos que podem prever o impacto dos processos hidrológicos de superfície no meio ambiente requerem dados hidrológicos de qualidade. São necessárias técnicas inovadoras e económicas para obter dados hidrológicos de boa qualidade em experiências de campo e de laboratório. A presença de pedras é uma propriedade importante do solo. Identificar a relação entre as pedras e fragmentos de rocha e os processos hidrológicos subsuperficiais é um grande desafio, mas é essencial para o desenvolvimento de medidas de conservação da água do solo para esses solos pedregosos. A presente tese concentra-se em dois objetivos principais. O primeiro é melhorar a compreensão do impacto que as pedras têm nos processos hidrológicos de superfície e subsuperficiais à escala de parcela e da bacia de drenagem. O segundo está relacionado ao desenvolvimento de técnicas inovadoras de medição e ao desenvolvimento de modelos matemáticos relacionados aos processos hidrológicos de superfície. A pesquisa relativamente ao primeiro objetivo começou por comparar a influência da geometria da superfície do solo e diferentes distribuições da cobertura de fragmentos de rocha no escoamento superficial e perda de solo, em condições controladas de laboratório. Três padrões diferentes de cobertura de pedras em superfícies planas, convergentes e divergentes, foram testados para uma chuvada tipo. Esse estudo concluiu que a geometria da superfície do solo tinha mais influência que os padrões de distribuição das pedras na severidade do processo de erosão. O estudo seguinte comparou a resposta da água no solo de solos pedregosos com o escoamento medido de bacia de drenagem, à escala da encosta. A resposta da água no solo induzida pela chuva foi simulada em três locais da bacia hidrográfica usando o modelo Hydrus-2D. Os solos nesses locais tinham pedregosidade entre 10-65%. Os parâmetros hidráulicos do solo usados nas simulações numéricas, ou seja, a condutividade hidráulica saturada e os parâmetros das curvas de retenção de água no solo, foram obtidos pela abordagem do Volume Elementar Representativo (REVa) e pela Modelagem Inversa com o modelo Hydrus-1D (IMa). As formas dos hidrogramas de água do solo simulados foram semelhantes às medidas formas dos hidrogramas de escoamento superficial das bacias para cerca de metade dos eventos de chuva. Além disso, os parâmetros hidráulicos do solo derivados do REVa produziram formas mais realistas de hidrogramas da água do solo do que os do IMa. A pesquisa para o segundo objetivo começou por testar a capacidade de um novo traçador térmico (gotas de óleo arrefecidas) para estimar as velocidades de escoamentos superficiais pouco profundos (<2 mm de profundidade) usando a técnica de velocimetria de rastreamento de partículas (PTV), baseada em infravermelho, sob condições controladas de laboratório. Esta nova abordagem foi comparada com o método do traçado colorido e a técnica PTV convencional (usando grânulos de poliestireno como traçador e uma câmara de vídeo) num regime de escoamento quase laminar. Os resultados mostraram que as velocidades estimadas das técnicas PTV convencionais e as baseadas no infravermelho estavam mais próximas das velocidades médias obtidas pelo método de volumétrico do que as velocidades do método de traçado colorido. Esta pesquisa enfatizou o potencial da técnica PTV baseada no infravermelho para estimativa das velocidades de escoamentos pouco profundos devido à alta visibilidade do traçador e independência das condições de iluminação. Por último, foi desenvolvido um modelo de escoamento superficial 1D, fisicamente baseado, que usa a teoria da cascata de planos para a estimativa do escoamento superficial, infiltração e erosão hídrica do solo em superfícies convergentes e divergentes. As simulações do modelo foram avaliadas comparando os resultados numéricos com dados medidos em laboratório. Os resultados indicaram que o modelo podia ajudar a aprimorar a modelação do escoamento superficial pouco profundo e a erosão do solo em superfícies planas convergentes e divergentes.

Abstract:
Regional sea level changes occur at different time scales. Global warming of the oceans, glacial and polar ice melting and meteorological or hydrological factors are major contributors to long-term sea level rise. In the recent years, a lot of attention has been paid to research concerning sea level change and seasonal fluctuations. The main objective of this paper was to determine the seasonal variability in the Baltic Sea level using satellite altimetry data for the period 1 January 2010 – 31 December 2014. The ANOVA analysis of variance was used in the research in order to estimate seasonal fluctuations. This study focused on investigate the monthly and annual amplitude in sea level anomalies over a given time period. The results from research showed that the amplitudes of fluctuations are the highest in winter and the smallest in summer in three analyzed points of the Baltic Sea. The results can bring valuable information about ongoing aspects in sea level changes, as a way of tracking climate change.

Abstract:
The safety assessments of potential geological repositories for spent nuclear fuel in Sweden are supported by modelling of groundwater flow in rock, to predict locations (exit points) where radionuclides from the deep repository may enter land, surface waters and associated ecosystems above the rock. This modelling includes detailed rock descriptions, but simplifies the upper part of the flow domain, including representations of meteorological processes and interactions with hydrological objects at the surface. Using the Laxemar candidate site as example, this paper investigates some potentially important consequences of these simplifications. Specifically, it compares particle tracking results obtained by a deep-rock groundwater flow model (CONNECTFLOW) and by MIKE SHE-MIKE 11, which contains detailed descriptions of near-surface/surface water flow. Overall, the models predict similar exit point patterns, occurring as clusters along streams in valleys, at a lake, and in sea bays. However, on a detailed level there are some prediction differences, which may be of importance for biosphere-focused safety assessments. CONNECTFLOW essentially predicts flow paths through the repository that follow fractures and deformation zones, outcropping in valleys. In comparison, MIKE SHE-MIKE 11 provides more detailed information on near-surface water flow paths, including the associated exit points and inputs to assessments of radionuclide retention.
