▼ Plastic material is now a ubiquitous source of aquatic pollution, most of which originates from sources on land, including surface waters. Microplastics- tiny plastic pieces that are often not visible to the naked eye, are a recent growing environmental concern in both marine and freshwater ecosystems. While many studies have proven the abundance and danger of microplastics in the world’s oceans, far less research has been done on their presence and impact in freshwater ecosystems. This exploratory quantitative study aims to build on the findings of recent freshwater microplastic studies by reporting on the abundance and types of microplastic pollution found in the West Fork of Indiana’s White
River. Fifteen surface
water samples were taken from three bridge sites along the
river over a four-month period (August-November 2015). Samples were collected with a custom adapted net and analyzed using NOAA’s recommended laboratory methods for the analysis of microplastics in the marine environment. Analysis revealed a variety of microplastic particles at all three sampling sites, to varying extents, with synthetic fibers being the predominant plastic type collected. A total of 145.5 plastic pieces were collected from the White
River over the duration of this study, from all 15 samples (which were averaged with duplicates). The average microplastic concentration in the White
River, based on the average concentrations of the three sites sampled, was 0.71 items/m3. These findings help to fill the large knowledge gap in microplastic research on freshwater, especially fluvial, environments and guide researchers in better understanding the extent to which these synthetic particles are polluting U.S. surface waters as a whole.

▼ The groundwater potential assessment of Teji
river catchment is important to the currently
increasing demand of
water resources for different developmental activities and its
quantification is vital for the efficient and sustainable groundwater resource management.
The most important parameter contributing to recharge in the area are rainfall,
evapotranspiration rate, and soil types. The area has an annual rainfall of 1104mm.
Quantification of potential and actual evapotranspiration of the area is made using
different techniques. The results obtained from are compared and representative one is
determined to the area and qualitatively described.
Water balance studies of the
catchment indicate that 325.39mm of
water is recharged annually and the months
October, November, December, January, February, March, April, and May have soil
moisture deficit and the remaining months are soil moisture surplus.
The main aquifer identified in the catchment is alluvial sediment, weathered and fractured
ignimbrite, and weathered and fractured basalt.
Graphical presentation using Piper, Shoeller, Stiff and Wilcox diagram have been used
for the effective analyses and interpretation of data. The groundwater in the catchment is
characterized by Ca-Mg-Hco3, Ca-Na-Hco3, Ca-Hco3 and Na-Hco3-cl type
water. TDS,
EC and PH values range 184mg/l-566mg/l, 354μs/cm-838μs/cm and 6.6-7.68
respectively. The
water sample analyses made in the catchment indicate the
water is
suitable for domestic and agricultural purpose. Almost all the
water samples analyzed are
with in the limits of WHO
water quality standards except bore holes drilled at Urogotade
PA’s (fluoride = 1.68mg/l) and Asgori town (fluoride = 2.01mg/l & iron=0.39mg/l).

▼ The objective of the study was to analyze households’ willingness to pay for protection of
river water pollution that attaches an economic value to the
river. The choice experiment technique was employed by means of interviewing 315 respondents. For the protection options, five attributes;
river water quality,
river water volume, riparian buffer zone, recreational facilities and monetary payments were identified and developed.
Attributes and socioeconomic characteristics were estimated using multinomial logit and random parameter logit models. Based on the best model fit, random parameter logit model with interactions result, respondents are willing to pay on average birr 90.34, 12.89 and 27.87 /respondent/year for additional level and birr 1.48/respondent/year for extra meter for
river water quality,
river water volume, recreational facilities and riparian buffer zone, respectively. Moreover, it is found that respondents are willing to pay on average birr 607.2, 753.2 and 886.2 /respondent/year for low, medium and high impact improvement scenarios. Priority should be given to the improvement of the
water quality, since households attached a higher value for the attribute of
river water quality.

▼ Groundwater and surface
water concentrations of selenium (Se) threaten aquatic life and livestock as well as exceed regulatory standards in Colorado's Lower Arkansas
River Valley (LARV). Se is naturally present in surface shale, weathered shale, and bedrock shale in the region. Excess nitrate (NO3) from irrigated agricultural practices oxidizes Se from seleno-pyrite present in shale and inhibits its chemical reduction to less toxic forms. Irrigation-induced return flows and evapotranspiration induce high concentrations of Se in the alluvial groundwater resulting in substantial nonpoint source loads to the stream system. This research uses three main components to address the need to better describe and find solutions to the problem of Se pollution in the LARV: (1) Se data collection in streams to characterize solute and sediment concentrations, (2) development of a conceptual model of in-stream Se reactions, and (3) application of existing calibrated groundwater models to explore alternative Se remediation strategies. Data in the form of Se solute samples, Se sediment samples, and related
water properties were collected during four different sampling events in 2013 and 2014 at several locations in the stream network in an effort to understand the various species of Se and how they cycle through the surface
water environment. A conceptual representation of the major chemical reactions of Se in the
water column and sediments of streams was described and incorporated into the OTIS (One-Dimensional Transport with Inflow and Storage) computational model of stream reactive transport for future coupling to the MODFLOW-UZF and RT3D-UZF groundwater models. The new version of OTIS, now called OTIS-MULTI, allows for simulation of the cycling of multiple Se species in the
river environment. Lastly, five best management practices (BMPs) were tested using MODFLOW-UZF and RT3D-UZF: improved irrigation efficiency (reduced irrigation), lining or sealing of canals to reduce seepage, lease fallowing of irrigated fields, improved fertilizer management (reduced fertilizer), and enhancement of riparian buffers. The impact of each of these BMPs on Se loading to the stream network was evaluated individually over three scenarios in which the adaption of each BMP is incrementally increased. In addition, various combinations of three and four BMPs were simulated and compared.
Water samples gathered from the Arkansas
River had total dissolved Se concentrations ranging from 6.1 to 32 μg/L (ICP method), compared to the Colorado chronic standard of 4.6 μg/L, while concentrations in samples gathered from tributaries ranged from 6.04 to 29 μg/L (ICP method). The groundwater and drinking
water standard from the National Primary Drinking
Water Regulations for selenium is 50 μg/L (USEPA, 2016). Concentrations of total Se (sorbed, reduced, and organic) in
river bed sediments ranged from 0.16 to 0.36 μg/g with concentrations in
river bank samples ranging from 0.26 to 1.78 μg/g. About 70 to 80% of Se in bed and bank sediments was found to…

▼ The agricultural sector and communities in the lower Red
River Valley in Manitoba have suffered a number of
water related problems since the Basin was first settled. Initially a massive drainage system had to be constructed to render much of the area suitable for agricultural production. Major floods and droughts have also plagued the area, resulting in direct measurable costs to area residents and businesses. In a more direct manner, the development of the area has been adversely affected by limited supplies of potable
water, and due to a lack of irrigation
water, the area has not been able to realize its full development potential. These problems became particularly acute between 1965 and 1980. During this period major Red
River floods occurred in 1965, 1966, 1969, 1974, 1975, 1978 and 1979. In the sixty-five years previous to this period, there were only three major floods. Major drought occurred most recently in 1973, 1974, 1977 and 1980. Inevitably there was a public outcry for senior levels of government to initiate preventive action rather than merely providing compensation for losses. However, government has been slow to respond resulting in public frustration and disaffection. This study can be divided into three sections. The first four chapters deal primarily with the history of
water management, tracing the evolution of policy and attitude, the transfer of responsibility from local government to more senior levels of government, and the evolution of institutional and methodological obstructions to resolving some of the recurring
water management problems. The next four chapters examine the current situation in terms of potable
water supply, the advantages and disadvantages of large scale irrigation and the controversy over solutions to flooding. The last chapter is comprised of a summary and recommendations. A common theme throughout the paper is the fact that regional economic development is the ultimate goal of
water management. However, policy decisions seem to have devolved from the elected representatives of the people to the technocrats, thereby limiting public recourse to unsatisfactory decisions. The technocrats' approach has been to disassociate development from
water management due to an over-reliance on benefit-cost analysis of site-specific, problem-specific issues. In view of the fact that public input is limited and the public perceives government action as wholly inadequate, this paper seeks to empower people to act.

▼ While the general biological processes of decomposition are known to forensic anthropologists, data on aquatic decomposition is in need of refinement. Water composition varies in mineral content, temperature, flow rate, and scavengers; each of these elements can have an effect on the rate of decomposition. This study specifically focuses on the effects of river flow rates on decomposition by comparing the rate of decay of three feral pigs (Sus scrofa) on land (control specimen), in faster flowing water, and in slower flowing water. The hypothesis states that the pig placed in the faster section of the river will decompose more quickly due to increased water flow which would cause the flesh to deteriorate more quickly.
Three feral pigs weighing approximately 100 pounds each were deposited at their respective research sites on the Amite River at Galvez Landing in Prairieville, Louisiana. Each pig was protected from large scavengers by a thick wire cage equipped with a water temperature data logger. The river subjects were secured to the bank by an industrial chain kept afloat by boat bumpers.
Daily visits to the site revealed that the control pig was skeletonized in two weeks and both water pigs were reduced to a few bones by the end of three weeks. Maggot activity and the presence of fish differed between the two water specimens, but the pigs decomposed at similar rates. Based on the conditions in this study, the hypothesis was rejected as the observed river flow rates did not seem to impact the decomposition rates of the pigs. Further studies with stronger velocity differences should be performed to determine the rate at which water flow does impact decomposition. This study indicates that each environment is distinct and caution must be taken when managing aquatic forensic cases.

▼ Shasta Reservoir maintains critical stream habitat by releasing cold-
water on the Sacramento
River to almost ~50 miles downstream in support of seasonal spawning runs of endangered fish species. Successful stream temperature management requires sufficient cold
water assets in the reservoirs throughout the summer and fall. Climate change has the potential to alter current management operations based on recent indications of seasonal shifts in mountain watershed runoff. This study explores seasonal and multi-year operational sensitivities in the Shasta Reservoir watersheds and the sensitivities those shifts will have on critical stream habitats. Community Climate System Model 3 data developed by the National Center for Atmospheric Research community will be used to generate runoff from 2000 -2099 on the upper watershed of Shasta Reservoir. Four climate change scenarios, namely the A1B, A2, B1, and IPCC scenarios are selected for this study. Runoff patterns were routed through Shasta Reservoir and coupled with the Sacramento
River Water Quality Model to quantify sensitivities in stream temperature.
In the summer of 2037 and 2038, stream temperatures downstream from the dam were elevated above the suitable temperature threshold of 56oF for all climate change scenarios. Stream temperatures were elevated at most by 2oF. A more persistent six-year dry cycle from 2091 to 2096 also had great implications on stream temperatures. Stream temperatures downstream from the dam were elevated (at most ~10oF) above the suitable temperature threshold of 56oF. All climate change scenarios had stream temperatures elevated above 56 oF in the summers of 2093 through 2095. Shasta Reservoir reached dead pool from November 2094 to February 2095. At dead pool, cold-
water in the reservoir is depleted, and accessibility to
water becomes an issue. Sustained six-year dry cycle will likely result in lack of
water behind the reservoir, and cause elevated steam temperatures, which is rendered as unsuitable for habitats spawning.

▼ The objective of the thesis is to investigate stakeholders’ perspectives of the impacts of pollution in the Jordan
River Valley and the Zarqa
River Basin in Jordan (Arabic: الأردن Al-Urdunn). The impacts that pollution has on stakeholders are varied and include physical, emotional, and spiritual impacts.
Classical Islamic Hermeneutics is used as a qualitative methodological approach. Semistructured face-to-face interviews were conducted with 50 participants to understand the environmental effects of contamination in the study area. The interviewees included residents, local farmers, environmental experts, government, NGOs and religious actors. Five in-depth interviews with
water industry actors were also undertaken in order to understand
water management issues in Jordan.
The study finds that
water pollution in the Jordan
River Valley and the Zarqa
River Basin has affected the economy of the farming community. The pollution has affected the level of income which resulted from farming owing to farmers’ using inadequately treated sewage
water to irrigate high-value crops. Furthermore, using partially treated sewage
water for irrigation causes additional maintenance costs owing to blockage of the irrigation networks.
The pollution has also impacted classical and religious sites on and around the Jordan
River Valley and the Zarqa
River Basin and led to the loss of fauna and flora. Overall, contamination has had negative impacts on religious, domestic, and international tourism.
The effects of pollution, which include pathogens, bad smells, and the spread of harmful insects such as flies and mosquitoes, have also impacted the health, emotional, and spiritual life of the local community in the Jordan
River Valley and the Zarqa
River Basin. The interviews revealed that institutional factors such as nepotism, the lack of enforcement of environmental laws, and the lack of political will have led to a lack of accountability. The lack of political will to enforce environmental laws has contributed to the increasing levels of contamination in the region and caused hardships in the community.
The contribution of this research is to allow those stakeholders’ whose voices are not usually heard to contribute to a level of commentary that might encourage the government to take action. At a broader level, the research elucidates the issue of
water scarcity in the Middle East and North Africa countries, many of which are experiencing similar issues to Jordan’s. The classical Islamic Hermeneutics approach is a beneficial approach that can be applied to research in other situations.
When compared to western countries, the political factors in Jordan, the Middle East, and North Africa are about more than merely managing
water. These factors include cultural factors, specifically existing rights and relationships and nepotism. In this context,
water management is much more than a technical issue and is also related to political will. Politicians as well as senior managers in the Jordanian
water authorities will need to work with…

▼ Governance of transboundary water systems is complicated by factors such as institutional fragmentation, social and environmental change, competing values for and uses of water and power dynamics. These challenges exist in both international and federal transboundary contexts, although much of the scholarly attention has been on international transboundary watersheds. Sustainable transboundary water governance is an important goal given the fact that freshwater ecosystems are among the most rapidly degrading in the world. Governance, the ways in which decisions are made and implemented, can have a critical role to enable sustainability in transboundary watersheds. Many analyses of transboundary water systems provide only partial accounts of transboundary water governance because they focus primarily on the roles of governments and interjurisdictional institutions. Furthermore, analyses of federal transboundary water systems have not satisfactorily considered the role of power dynamics as possible constraints on transboundary water governance. Appreciation of the full complexity of transboundary water governance, and factors that constrain and enable sustainable transboundary water governance, requires considering governance processes at multiple levels and the variety of actors that may be involved therein. A power-analysis can facilitate consideration of which interests are advantaged in various governance processes that have implications for sustainable transboundary water governance.
The purpose of this study is to explore factors that constrain and enable sustainable transboundary water governance in a federal transboundary water system. Explicitly assessing multi-level governance processes, and the ways in which power dynamics impact them, facilitates a consideration of their roles and contribution to transboundary water governance. This study’s purpose is achieved via the following objectives: 1) identify the jurisdictional levels at which federal transboundary water governance takes place in the Mackenzie River Basin, (MRB), Canada; 2) consider the design and performance of an interjurisdictional river basin organization (RBO) in the MRB; 3) determine the ways in which power dynamics impact a) collaboration and b) water use decisions within jurisdictions in the MRB; and 4) assess the role and contribution of a) an RBO, b) collaboration and c) water use decisions within jurisdictions to transboundary water governance within the MRB. Single and multiple case studies and qualitative data collection and analysis methods were used to achieve these objectives. Two hundred and ninety-six documents, 30 interviews and personal observations were collected and analyzed to achieve the study objectives.
The MRB, a jurisdictionally and ecologically complex federal transboundary system in which three provinces, three territories, a federal government and Indigenous governments have responsibilities for water, provided an excellent empirical context in which to explore these issues. Upstream hydroelectric developments…

▼ ENGLISH ABSTRACT: The investigation of Western Cape Rivers has highlighted the importance of the implementation of cost-effective, on-farm disinfection treatments solutions. Irrigation
water, if used untreated, has the potential to be a serious health hazard as faecal coliform (FC) levels often far exceed the allowable limit of 1 000 FC per 100 mL
water. Chlorine (Cl), peracetic acid (PAA) and hydrogen peroxide (H2O2) are popular chemical disinfectants that have been used in
water disinfection over the years. On-farm ultraviolet (UV) irradiation, a less conventional
water treatments option, can also prove to be advantageous for
water treatment. The aim of this study, therefore, was to investigate the application of chemical treatments in combination with UV irradiation in the disinfection of
river water used for irrigation.
Initially, the efficacy of Cl, PAA and H2O2 in combination with low-pressure (LP) UV (Cl+UV; PAA+UV; H2O2+UV) required evaluating the stand-alone efficacy of each treatment first. Environmental Escherichia coli (E.coli) strains, F11.2 and MJ58 when exposed to Cl (6 mg.L-1) and H2O2 (2.5 mg.L-1) showed much resistance to disinfection. Strain F11.2, showed much greater sensitivity to PAA (4 mg.L-1), recording > 3 log reductions for both 15 and 25 min contact times. However, LP-UV doses of 13 mJ.cm-2 proved more effective than any of the chemical disinfectants for the E. coli strains. Combination treatments did not show much evidence on the initiation of advanced oxidation processes (AOPs) as the sum of the individual treatments more clearly justified the log reductions recorded.
An additional study investigated the impact of
river on disinfection treatments whilst keeping the chemical and UV doses the same as in the first study. Considering the variability in the physico-chemical properties of the
river water, Cl most effectively reduced the TC and FC groups, recording no less than 2.9 log reduction for TC and well over 3 log reduction for FC. PAA and H2O2 showed highly compromised disinfection and were unable, as stand-alone treatments, to offer adequate defence against the naturally present microorganisms in the
river water. However, residual Cl levels of > 1 mg.L-1 measured, post-treatments is of concern, as the formation of disinfection by-products (DBPs) is unwelcomed. UV treatments showed to be greatly influenced by poor ultraviolet transmission percentages (UVT%) and turbidity, which greatly decreased its effectiveness. Assessing the benefits of combination treatments, if any, through the initiation of AOP proved redundant as UV treatments were so effective.
The efficiency of medium-pressure (MP) UV irradiation (25 – 30 mJ.cm-2) at pilot-scale, was able to, in some instances, successfully reduced FC levels by over 3 log. However, significantly poorer (p<0.05) disinfection was reported for all the chemical treatments. UV irradiation was again directly affected by poor optical
water characteristics measured for the
river water.
Cl disinfection, dosed at 3 mg.L-1, half that of the dose used…

▼ Since the demand for fresh potable
water increases
every year, it is important to have future
water demand strategies
in place. People expect a secure, high quality,
water supply and
the
water supply industry is governed by increasingly stringent
water quality guidelines and legislation. The Cape Metropolitan
Area (CMA) faces the challenge of an increasing demand for fresh
water in excess of the existing supply. The City is responsible for
the planning and development of the local
water supply resources as
well as managing the
water demand in the CMA and to supplement the
water supply to the City of Cape Town from local sources. The
‘Voëlvlei Augmentation Scheme’ was identified as one of the options
to augment the
water supply to the CMA. This option would involve
pumping winter
water from the Berg
River via a pipeline to the
Voëlvlei
water treatment plant (WTP). The Voëlvlei WTP was designed
to treat
water from the adjacent Voëlvlei Dam. This Voëlvlei WTP
raw
water has a higher turbidity and a lower colour in comparison
to the Berg
River water. The plant’s treatment conditions were
optimized to remove this high turbidity. The Voëlvlei WTP raw
water
also contains a relatively high manganese concentration and
coagulation therefore occurs at a high pH with ferric sulphate to
remove the manganese during the initial stages of the
water
treatment process. As the quality of the Berg
River water is
different to that of the Voëlvlei WTP raw
water, it might not be
possible to treat the Berg
River water at the Voëlvlei WTP using
the plants current treatment parameters. The Berg
River water could
possibly be blended with the Voëlvlei WTP raw
water before
treatment at the WTP. If the Berg
River water, or its blends, could
not be treated at the Voëlvlei WTP using the plants current
treatment parameters, then this
water would have to be pre-treated
before entering the plant. Various forms of pre-treatment could be
used, e.g., conventional
water treatment using either aluminium or
ferric sulphate as primary coagulants or ion-exchange
water
treatment using the MIEX® resin or even a combination of both. The
main objective of this study was to determine a treatment strategy
for the Berg
River water at the Voëlvlei WTP. It is therefore
important to determine if the Berg
River water could be treated at
the Voëlvlei WTP using the current treatment regime. Also, if the
Berg
River water should be blended with the Voëlvlei WTP raw
water,
this study would determine which blend would be the most suited for
treatment at the Voëlvlei WTP. If the Berg
River water could not be
treated directly at the Voëlvlei WTP, a pre-treatment strategy for
this
water should be determined. The cost of pretreatment of the
Berg
River water as compared to the cost of direct treatment at the
Voëlvlei WTP should also be evaluated. In order to determine the
best treatment strategy for the Berg
River water at the Voëlvlei
WTP, it was important to sample the Berg
River water and the
Voelvlei WTP raw
water at regular intervals over a period of at
least a year to…

▼ The Upper Mississippi
River National Wildlife and Fish Refuge (UMRNW&FR) is a 418 km long refuge that lies within the Mississippi Flyway. Over 40% of the nation's waterbirds use the Mississippi Flyway to navigate to and from their reeding grounds in the spring and fall. Since 2002, large waterbird mortality events caused by the parasitic trematodes, Cyathocotyle bushiensis (Digenea: Cyathocotylidae) and Sphaeridiotrema spp. (Digenea: Psilostomidae), have been occurring within the Refuge's boundaries. The parasites use the prosobranch snail, Bithynia tentaculata as first and second intermediate hosts. Although B. tentaculata and its parasites have caused seasonal waterbird mortality events, little is known about the spatial or temporal distributions of these snails and their trematodes in the UMRNW&FR. The onjectives of this study were to quantitatively sample both B. tentaculata densities and parasites intensities in waterbird stopover areas across space and time, and to map disease risk with the use of Geographic Information System (GIS). Snails with primary and secondary infections were found to vary in infection prevalence and intensity across 2 navigation pools of the UMRN&FR.

▼ Os rios são elementos biofísicos e paisagísticos fundamentais no território, e
sempre tiveram um papel relevante na ciência geográfica. Delimitam territórios,
determinam localizações, movimentos e distribuições, têm impacto no clima, no cultivo,
na urbanização, nos usos e atividades económicas. Ao longo dos tempos o uso do rio foi
sendo modificado, e se inicialmente era caracterizado pelas necessidades humanas de
sobrevivência e transporte, assistindo-se à instalação de muitos povos nas margens dos
rios, mais tarde, na era industrial foram fortemente usados com consequências negativas
para os ecossistemas fluviais, fruto do uso da sua água e energia, e das descargas de
resíduos. Atualmente, os rios têm um papel importante na indústria e na urbanização, mas
são também alvo de consumo, com especial relevo para o turismo e lazer, trazendo em
muitos casos benefícios para as economias locais.
O turismo fluvial deve assentar numa exploração sustentável dos recursos
naturais, visando a proteção de um ambiente frágil e o equilíbrio do ecossistema aquático.
As entidades responsáveis pelas questões da água, tentam assegurar a sustentabilidade de
um recurso (água potável), que cada vez mais escasso, é sinónimo de vida.
Nesta dissertação propõe-se estudar o turismo fluvial no rio Tâmega e a sua
importância no desenvolvimento territorial, avaliando as potencialidades turísticas dos
rios da sua bacia hidrográfica e dos municípios por eles banhados. A metodologia usada
consistiu em visitas a vários pontos dos rios, na participação no evento anual “Tamecanos
2013” e na realização de entrevistas com os utilizadores do rio.
Desta forma, pretende-se conhecer qual a atual dinâmica turística ligada ao rio
Tâmega assim como entender as razões que levam os turistas a optarem pelos rios da
região. Este estudo visa assim contribuir para o panorama nacional do Turismo Fluvial,
caracterizando as potencialidades turísticas de uma área específica (Rio Tâmega), para o
desenvolvimento de uma atividade turística que pode ser sustentável.

▼ As a consequence of climate change, many populations of sockeye salmon in the U. S. Pacific Northwest are now experiencing significantly warmer river conditions during their spawning migration from the ocean to their freshwater spawning grounds compared to the 30 year average. The Columbia River witnessed an extended heat wave in 2015 and low flows pushed water temperatures to 21° C, which ended up killing 90 percent of the adult sockeye salmon returning to spawn in their natal streams in the summer months. Fish passage delays at hydro-electric dams potentially compounded this effect. The purpose of this study was to determine if water temperatures had a delay effect on run-timing and potential returning sockeye salmon population mortality in the Snake River in the Columbia Basin. Run timing and delays in migration patterns were examined over the years 2014-2018 in order to notice any trends in migration patterns. Results indicated that, as water temperatures increased, so did the travel time of returning adult sockeye salmon migrating between Bonneville Dam and Lower Granite Dam. Increased water temperatures were associated with migration delays, increasing them by as much as ten days more than the average in some years. Qualitative observations of fish vigor on migrating fish through fish windows also yielded signs of fungal disease on a small number of sockeye salmon during warmer water temperature outbreaks.

▼ This study investigated temporal changes in nutrient concentrations and other
water quality parameters at one sampling location at Muncie, Indiana in the Upper White
River Watershed. Baseline sampling was conducted weekly over a six-month period in 2012 and focused on the analysis of total suspended solids and different forms of nitrogen and phosphorus. Three storm events were also investigated to understand how storm
water runoff affected nutrient concentrations and other
water quality parameters. It was hypothesized that storm events would temporarily increase nutrient concentrations in the
river. Overall, nutrient concentrations increased during the initial stages of storm events and subsequently decreased at a rate slower than discharge. Concentrations measured exceeded recommended limits suggesting that these contaminants could cause eutrophication at downstream locations. These data suggest that improved or increased best management practices should be implemented in the Upper White
River Watershed to control the inputs of nutrients into the
river.

▼ In transboundary
water resources policy and management situations, such as the governance of the Columbia
River Basin, complex social, ecological, and economic factors seem to be in irreconcilable competition with one another. However, cooperative negotiation provides an outlet for entities and stakeholders to "expand the pie" and develop creative alternatives for integrated, resilient management. To achieve these goals, it is critical that stakeholders have meaningful dialogue that goes beyond positions to identify the underlying values and interests in the basin. Furthermore, parties must develop a shared understanding of the substantive complexities of the social-ecological system. Collaborative learning allows participants to meet both of these objectives at once, and facilitators can spark collaboration through carefully planned interventions. The goal of this study was to test a carefully crafted "facilitative" documentary film as a facilitation tool to promote dialogue, understanding, and creative scenario development amongst parties. The study has three main components: 1) the resilience and learning analysis of the case study (the Columbia
River Treaty) policy situation, 2) the creation of a facilitative film featuring interviews with diverse stakeholders in the basin, and 3) the qualitative and quantitative assessment of the effects of the film in the cooperative negotiation process. The film, A
River Loved: A film about the Columbia
River and the people invested in its future, premiered at the Universities Consortium Symposium on Columbia
River Governance- an informal forum for dialogue held in Kimberley, British Columbia in October 2011. I measured participants' reactions to the film and found substantial support for my hypotheses, concluding that interventions such as facilitative documentary film have great potential to transform complex, multi-stakeholder social-ecological policy situations.

▼ High
water temperatures in rivers have detrimental effects on riverine
water quality and ecology. In this study, two
river temperature models, within the agricultural watershed model Soil and
Water Assessment Tool (SWAT), were investigated for their ability to simulate
water temperatures accurately throughout the year. The original temperature model within SWAT uses a linear approach to estimate stream temperature based on air temperature and does not account for hydrological components for calculating stream temperature. Recently, a new stream temperature model for SWAT was developed that combines meteorological with hydrological components such as lateral flow, snowmelt, groundwater flow and surface runoff. The model also uses three elements for the stream temperature calculations – specifically, within a sub-basin (temperature and flow rate), upstream of sub-basin (temperature and incoming flow), and air-
water temperature heat exchange transfer. The goal of this research was to improve the recently developed temperature model further by incorporating different types of heat exchange sources, in addition to air-
water heat transfer. The edited model was tested for Marys
River, a west tributary of the Willamette
River in Oregon. The output from the edited model was then compared with observed stream temperatures, for different spatial locations within the watershed to assess the model efficiency. The results showed a good agreement for forested region compared to Ficklin’s default model with RMSE of both models matching. However, there were over predictions and more noise in predicting stream temperature for agricultural region within the watershed in which resulted in higher RMSE for edited model.

▼ For decades, Polychlorinated Biphenyls (PCBs) have been recognized as important and
potentially harmful environmental contaminants. fhe intrinsic properties of PCBs, such as
high environmental persistence, resistance to metabolism in organisms, and tendency to
accumulate in lipids have contributed to their ubiquity in the- environmental media and
have induced concern for their toxic health effects in humans and wildlife after prolonged
exposure.
This research was carried out to establish the pollution status of I gong and Mathare Rivers
with respect to the seven UNEP indicator PCBs and two additional ones (PCB 105 and
156). This was accomplished by determining their spatial and temporal distribution in
water and sediments from the two rivers and correlating the levels with physicochemical
parameters of water.
Field samples were collected monthly between vlarch and September 2009 from 7 sites
along the Ngong and Mathare rivers representing upstream, middle stream and
downstream terraines. Analysis of PCB congeners was achieved on Agilcnt Gas
Chromatograph equipped with an electron capture detector after extraction with solvent
following the USEPA methods 3510 and 3540. Mean percentage recoveries of PCB
congeners were 85.85±5.40 and 88.71±5.68 in water and sediment, respectively, while the
instrument detection limit varied between 0.000 1'2and 0.00691 ng/L for PCB 118 and 180,
respectively.
PCB congeners' concentrations 111 water ranged from BDL. to 838.23 ng/L in water
samples from Ngong River and BDL to 307.12 ng/L in sam pies from Mathare River with
the highest mean PCB levels being observed in water samples from Donholm Bridge. PCB
congeners 28 and 52 were the most prevalent in all sites an.l throughout the sampling
period with occurrence frequency of 100%.
Residue levels of PCB congeners detected in sediments ranged from BDL-34.92 ug/kg in
samples from Mbagathi Bridge, 0.32-70.30 ~g/kg in samples from Mater Bridge and 0.9188.0
I ug/kg in samples from Donholm Bridge. Fhe frequency of occurrence of the PCB
congeners in sediments was 100% for all the congeners except for PCB 138 which was not
detected in 2 sampling sites ie Mbagathi and Mater Bridges in the month of April.
There was a general increasing trend in levels of individual PCB congeners as well as the
sum of PCBs downstream of both rivers. The PCB levels were several fold higher in
sediment than in water because PCBs are hydrophobic and tend to partition to the more
organic components of the environment hence adsorb strongly to organic matter in
sediments. The concentrations were higher during the dry m nths (March, August and
September) than in the wet months (April, June. July). There 'as a direct relationship of
PCB levels in water with physicochemical parameters (pH, TSS, TDS) as indicated b.' the
positive Pearson's correlation coefficient values. Generally, the average PCB
concentrations were below the USEPA allowable limit of 500 ng/L. However, with
bioaccumulation and biornagnifications, the levels pose adverse…

▼ The Dolores
River in Utah and the Virgin
River in Nevada are ecosystems under pressure from increased groundwater withdrawal due to growing human populations, climate change and introduced species such as Tamarix spp. (tamarisk). Tamarisk is reputed to take excessive
water from its environment. Controlling tamarisk is of concern in the western United States where plants grow quickly in already fragile and diminishing riparian areas. For this reason, biologic control beetles Chrysomelidae: Diorhabda carinulata were released to weaken the tamarisk population, thus reducing its
water use. The studies for this dissertation were conducted between 2010 and 2011. We quantified tamarisk
water use over multiple cycles of annual defoliation using sap flow measurements, leaf area index (LAI), well data, allometry and satellite imagery from EOS-1 Moderate Resolution Imaging Spectrometer (MODIS) sensor. Study objectives for the Virgin
River were to measure evapotranspiration (ET) before beetles ever arrived and to examine the effects on tamarisk ET in the year after beetle arrival. This site showed plant ET from sap flow averaged about 4.3 mm m⁻² leaf day⁻¹ in 2010. In 2011, ET from sap flow averaged 6.4 mm m⁻² leaf area day⁻¹ pre beetle arrival, but dropped to 3-4 mm m⁻² leaf area day⁻¹ after beetle arrival. Stand level ET measured by MODIS was 2.2 mm d⁻¹ in 2010 and approximately 1.5 mm day⁻¹ when beetle arrival was measured in 2011. Significant visual change was apparent as the trees senesced. Results showed the first year of beetle arrival resulted in reduced ET but did not result in significant
water savings. We also compared the reaction of the newly defoliated (in 2011) Virgin
River site to the long-term defoliated (since 2007) Dolores
River site to explore if all beetle invasions were created equal. This paper views the two sites as fairly extreme examples of tamarisk stand reaction to the beetle. While no mortality was reported at the Dolores
River site, the site is much older, less photosynthetically active and covers far less ground when compared to the younger tamarisk monoculture on the Virgin
River. Pre-beetle arrival Normalized Difference Vegetation Index (NDVI) values were higher on the Virgin
River than on the Dolores
River. Beetle arrival at each site was captured with Landsat NDVI and a reduced NDVI signal (13% drop in NDVI at Dolores
River, 5% drop at Virgin
River) was seen after beetle arrival.

▼ Nature-based
water management is rising as an alternative approach to engineered
water management. Nature-based
water management makes use of ecological, hydrological, and morphological processes of natural rivers in designing
river management policies. Furthermore, it helps conserving or restoring these natural processes for environmental purposes. Next to changes in
water management, changes in the earth’s climate are occurring, which decrease the
water flow in summer and autumn and increase the flow in winter. These changes will affect
river uses and might cause conflicts between them. The
river uses studied in this research are environment, navigation, and flood protection and an integrated model is developed to answer the research question: What conflicts arise between environment, navigation, and flood protection when nature-based
water management policies are implemented under different
water flow scenarios and how can insights in these conflicts be used in the policy-making process? The system dynamics (SD) modelling method has been used, because SD enables integration of physical, social and economic factors influencing
water resources while addressing inter-sectoral, long-term problems. The scope of the model has been set to analysing a side channel as a nature-based
water management example. The model has been built up of four sub-systems that are interrelated: the
river system (including a main channel, side channel, and floodplain), the environmental system, the navigation system, and the flood protection system. The model results show that no conflicts arise during high
water inflows. Furthermore, environment and flood protection or navigation and flood protection can find a solution that is beneficial (0r neutral) for both during low
water inflows. However, the environment requires a side channel that is connected on both its ends – and therefore has a year-round
water flow –, while navigation prefers a side channel that is only connected on its downstream end in order to prevent lowering of the
water level in the main channel during low
water inflows. Insights for policy-makers are found in five ways. First, the conflicts between
river uses do not necessarily arise regarding the side channel per se – but concern the configuration of the side channel. Secondly, the conflicts strongly depend on the changes in
water inflow due to climate change. Third, attention should be paid to compromises that are made. The side channel connected on one side can be seen as a compromise between nature and navigation and it indeed eliminates the negative effects on navigation, but it strongly reduces the benefits for nature. Fourth, for nature-based
water management to be truly effective for environmental purposes, integration of several measures is required. Finally, the model showed that system behaviour is strongly dependent on fixed standards (e.g. maximum amounts of vegetation and presence of summer dikes). The model that was developed in this research can also be used to study the effects of…

▼ A better understanding of fluvial adjustments to base level changes may benefit the fields of sequence stratigraphy, geomorphology and petroleum geology. This investigation provides a modern case study of the channel evolution of the Lee Creek and the Goggin Drain, two streams that flow into the Great Salt Lake, a lacustrine system that experiences rapid base level changes. Using aerial images, fieldwork and LiDAR data, a detailed study of geomorphology and channel hydraulics was conducted for the purpose of explaining variations in channel form and avulsion behavior. While Lee Creek, a meandering system, has not recently been avulsive, three major avulsions of the Goggin Drain have taken place since 1965. During this time, lake levels fluctuated from near their historic lowstand to their historic highstand, an elevational difference of more than 6m, and again approach lowstand in the present. Two possible styles of avulsion are interpreted: an allogenic response to changing base level, and an autogenic response dictated by channel morphology and hydraulics. Despite a wealth of available information for this system, avulsions cannot be positively attributed to one style or another; caution should be used when attempting to link the complex process of avulsion to causal mechanisms.

▼ Hydrodynamic characteristics of an estuary resulting from
interaction of tide and river runoff are important since problems
regarding flood, salinity intrusion, water quality, ecosystem and sedimentation are ubiquitous. The present study focuses on such
hydrodynamic aspects in the Cochin estuary.
Most of the estuaries that come under the influence of Indian
Summer Monsoon and for which the salinity is never in a steady
state at any time of the year are generally shallow and convergent,
i.e. the width decreases rapidly from mouth to head. In contrast,
Cochin estuary is wider towards the upstream and has no typical
river mouth, where the rivers are joining the estuary along the length
of its channel .Adding to the complexity it has dual inlets and the
tidal range is 1 m which is lower than other Indian estuaries along
west coast. These typical physical features lead to its unique
hydrodynamic characteristics. Therefore the thesis objectives are: I)
to study the influence of river runoff on tidal propagation using
observations and a numerical model ii) to study stratification and
property distributions in Cochin estuary iii) to understand salinity
distributions and flushing characteristics iv) to understand the
influence of saltwater barrage on tides and salinity v) To evaluate
several classification schemes for the estuary

▼ The inactivation fluence of a target wastewater plant
in Alberta, Canada was determined in the laboratory and was found
to be close to that reported by the target wastewater plant. The
effect of inactivation fluence, effective reactivation fluence,
temperature, and river water on the percent photoreactivation of
total coliforms was investigated under both indoor and outdoor
conditions. A concept, namely the ‘effective reactivation fluence’,
based on weighting the spectral fluence rate by the action spectrum
for photoreactivation, is introduced. Higher inactivation fluence
and effective reactivation fluence decreased the percent
photoreactivation of total coliforms, while higher temperature
increased it. Also, the percent photoreactivation of total
coliforms decreased on increasing the percent river water. In
addition, the effect of various covers on the percent
photoreactivation of total coliforms was studied representing
higher percent photoreactivation of total coliforms by cutting off
the UV-B portion of sunlight.

▼ Water supplies are a limiting factor in the Western United States. Policy, social welfare, and economic interests all reflect the demands placed on this scarce resource. Projects to develop
water are complex and reflect both historical and current institutional, environmental, and financial constraints. This study proposes a project from the Green
River Basin for use in the State of Colorado.
Water managers called this study the first new idea in
water resources in 50 years. The cost-benefit analysis identifies limits, constraints and opportunities from the Green
River Basin compared to the Colorado
River basin. Economic welfare issues reflect
water's expanding use and legal constraints. Not a public good exclusively and not a private right exclusively, the procurement of
water,
water rights, and development history is influenced by
water's legal standing, public policy, and economic benefits. In the western United States, the Colorado
River Compact influences the division and equitable use of waters in the Colorado
River Basin System. Significant infrastructure is part of the landscape influenced by the Compact and the need to allocate
water in a constrained system. Recent public project proposals failed to identify a potential
water supply from the Green
River. Environmental benefits, comparative costs, and financial opportunities may allow a new paradigm in the development of a major
water project by the private sector. The historic return to private development of
water projects reflects current policy changes and markets. The private sector may have significant advantages over public development and meet or exceed public welfare goals related to conservation, environmental benefits, protection of irrigated farmland, and supply procurement.

▼ The majority of people in Mizoram depend on surface
water bodies for their day to day life, as underground water is
hardly assessable in most parts of the state, due to predominance
of hilly terrain. The supply of treated water is limited, and
majority of rural people depend on untreated water for drinking and
other purposes. Major portion of domestic, agriculture, industrial
and other wastes are directly or indirectly discharged into the
rivers situated in the vicinity, as no proper drainage system has
been developed in the state so far. Thus, there is an ample need to
determine status of fresh water bodies in the state, and to develop
appropriate strategy for management of surface water bodies. In
view of this, the present research was taken up to determine
quality of water and biomonitoring of Tuirial river in vicinity of
the Tuirial Hydel Project, Mizoram. This study is also aimed to
determine how the bioindicators respond with intensity of
pollutants. Undoubtedly, the information procured from this study
would provide a needful dimension towards formulation of
appropriate water pollution abatement technique, which can be used
as a measure for management of aquatic bodies. Keeping in view the
components of hydro electric power projects, four sampling points
along the river bank namely, Site 1 - demarcated as reference
station which is at the upstream of dam; Site 2 - demarcated as
diversion inlet on river; Site 3 - demarcated as powerhouse outlet
and Site 4 - demarcated as diversion outlet situated downstream of
river were selected for detailed investigation. Water samples were
collected (at monthly interval) for a period of two years i.e.,
from January 2008 to December 2009, and analyzed for various
physico-chemical (temperature, total dissolved solids, electrical
conductance, pH, dissolved oxygen, biological oxygen demand, total
hardness, acidity, total alkalinity, chloride, fluoride, nitrate-N
and phosphate-P content) and biological characteristics (saprobic
score, diversity score, taxa richness

▼ This thesis examines the Indian government’s Namami Ganges project and related
river cleaning and sewage treatment projects along the Ganges
river in India. One of the challenges of these
water cleaning projects is that the waters of the Ganges are sacred to millions of Hindus, and interfering with the flow can cause significant cultural resentment and frustration. This design-led architectural research investigation looks at how
river purification and urban sewage management along the Ganges can be strategically integrated into urban architectural infrastructure in ways that enhance, rather than damage, cultural relationships that are fundamental with local communities. The thesis argues that by embracing architectural links to cultural narratives, these new industrial typologies can transform urban sites along the Ganges into rejuvenated public spaces, while reconnecting them to their environmental and cultural contexts.
This design-led research investigation proposes to develop embedded industrial filtration systems that are integrated into a framework that responds to the local identity. These can be integrated into efficient wetlands and bioswales to enhance the natural biodiversity of the area. This investiagtion examines how contemporary architectural design can help integrate effective pollution mitigation with the cultural, spiritual and pragmatic ways people actually use the
river basin. This investigation proposes that in this way the community’s cultural and civic needs can actually be enhanced through the use of design as architecture and landscape blended
water purification systems.

▼ Excess nutrients resulting in eutrophication of surface waters has become one of the greatest
water quality challenges of our time. The development of an effective nutrient management strategy is essential to protecting surface
water quality, public health, aquatic ecosystems and economic interests. The complexity of cultural eutrophication and the influence of nutrients, especially in streams and rivers, has delayed the development of an effective regulation and a nationwide management strategy. Variations in hydrologic conditions, geology and both urban and agricultural land use can dramatically influence phosphorus loads to receiving waters. Furthermore, several complex mechanism exist within a
river or stream (e.g. the phosphate buffer, light availability, hydraulic retention time, phosphorus spiraling, etc.) that change the concentration and impact of nutrient concentrations and resulting eutrophication. Temporal and spatial variations result in changing and often imprecise threshold between healthy and unhealthy ecosystems. For this reason, it is important for policy makers to understand how the assimilative nutrient capacity of waterways varies with environmental, seasonal and loading conditions, and that it is not the same for every watershed or even within the same waterway. A one-size-fits all technology solution or a state-wide numeric standard that does not account for these variations is misguided and will result in costly upgrades with minimal improvements to
water quality. The most efficient nutrient management method is one that best matches the nutrient load delivered with the maximum assimilative capacity of the receiving
water. This study provides an in-depth analysis of the Cache la Poudre
River Watershed in Northern Colorado over the course of a year to examine the influence of different sources, transport pathways and hydrologic regimes on phosphorus concentrations along an urban-agricultural gradient. An extensive and comprehensive design of sampling locations was used to best capture the anthropogenic influence (e.g. wastewater treatment plants, concentrated feeding animal operations, land uses) and transport pathways (e.g. irrigation ditches, overland transport, streams and rivers) of phosphorus within the watershed. Exploratory models were used to better understand the influence of geospatial variables on the occurrence and transport of phosphorus within the watershed. The influence of phosphorus from wastewater treatment plants (WWTPS) to the Cache la Poudre
River was examined in detail. A mass-balance of the phosphorus load in the
river and the effluent from WWTPs was used to best estimate the influence of WWTPs. Projections of the influence proposed regulations that reduce WWTP effluent concentrations were made as well as the resulting impact to the
river and
water quality. The role of sediment was investigated to better characterize and explain the temporal variations of phosphorus concentrations within this complex system. A brief economic analysis and associated improvements to
water…

▼ The Upper Souris River was placed on the Environmental Protection Agencies (EPA) impaired waters list for low dissolved oxygen (DO). A Total Maximum Daily Load (TMDL) study was conducted to determine possible causes of DO depletion. From sampling and site visits it was determined nonpoint sources contributed the majority of organic loadings to the Upper Souris River. Through preliminary testing, it was determined that sediment oxygen demand (SOD) played a key role in depleting DO levels during winter months and required further investigation. River profile surveying, water quality sampling, and laboratory testing of SOD were carried out to determine parameters required for water quality modeling. SOD tests were conducted to determine impacts of sediment organic contents and temperature on SOD rate. Sediment oxygen demand rates ranged from 0.37 to 1.22 g O2/m2/d. The QUAL2K model was calibrated to simulate DO variations along the study reach under ice covered conditions.

▼ The goal of my graduation project is an intervention on three scales: the regional, local and zooming in on the border of two cities where the site is. The analysis of the region led to a understanding of Rio Grande challenges with the focus on El Paso/Juarez where the river stops. The research on a local scale advantage at finding a new strategy which reestablish the river border while solving crucial environmental issues (evaporation, pollution) as well. The new plan is based on the fact that the agriculture was relocated, hence, the location of the canals needed to be changed as well. Finally, on the smallest scale, my design assignment is the development of a new dam which replaces two old ones. The intervention is not only used to divert the water to new canals, but also to collect the surface water (Rio Grande) and treat it to the drinking standard in order to supply El Paso centre and Chamizal area with fresh water. Thus, my project becomes a sustainable water hub, which does not only respond to the issues on the small scale, but also solves the river border challenges.
