This decision-support system can be used for six LID types and has the following key capabilities: determining relevant LID design parameters within the SWMM that critically influence the hydrological cycle components using a simple sensitivity analysis and determining the best hydrological values for LID planning specification. This study analyzed a highly urbanized university campus as a case study to determine the design and planning specifications for an …

Global Anthropogenic Phosphorus Loads To Freshwater And Associated Grey Water Footprints And Water Pollution Levels: A High-Resolution Global Study, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

We estimate the global anthropogenic phosphorus (P) loads to freshwater and the associated grey water footprints (GWFs) for the period 2002–2010, at a spatial resolution of 5 3 5 arc min, and com- pare the GWF per river basin to runoff to assess the P-related water pollution level (WPL). The global anthro- pogenic P load to freshwater systems from both diffuse and point sources is estimated at 1.5 Tg/yr. More than half of this total load was in Asia, followed by Europe (19%) and Latin America and the Caribbean (13%). The domestic sector contributed 54% to the total, agriculture 38%, …

Assessing The Impacts Of Climate Change On Streamflow And Reservoir Operation In Central Florida, Toni Panaou

USF Tampa Graduate Theses and Dissertations

Climate change is a global concern as it may affect many aspects of life, including water supply. A tool used to model climate change’s impacts is called a General Circulation Model (GCM). GCMs project future scenarios including temperature and precipitation, but these are designed at a coarse resolution and require downscaling for employment for regional hydrologic modeling. There is a vast amount of research on downscaling and bias-correcting GCMs data, but it is unknown whether these techniques alter precipitation signals embedded in these models or reproduce climate states that are viable for water resource planning and management. Using the Tampa, …

Riverbank Filtration Impacts On Post Disinfection Water Quality In Small Systems—A Case Study From Auburn And Nebraska City, Nebraska, Matteo D'Alessio, Bruce Dvorak, Chittaranjan Ray

Nebraska Water Center: Faculty Publications

Small water systems can experience a fluctuating quality of water in the distribution system after disinfection. As chlorine is the most common disinfectant for small systems, the occurrence of disinfection byproducts (DBPs) represents a common problem for these systems. Riverbank filtration (RBF) can be a valuable solution for small communities located on riverbanks. The objectives of this study were to evaluate (i) the improvements in water quality at two selected RBF systems, and (ii) the potential lower concentrations of DBPs, in particular, trihalomethanes (THMs), in small systems that use RBF. Two small communities in Nebraska, Auburn and Nebraska City, using …

The Sonoma County Water Agency (SWCA) uses six radial collector wells along the Russian River west of Santa Rosa, to provide water for several municipalities and water districts in north-western California. Three collector wells (1, 2, and 6) are located in the Wohler area, and three collector wells (3, 4, and 5) are located in the Mirabel area. The objective of this paper is to highlight the performance of the three collector wells located in the Mirabel area since their construction. The 2015 investigation showed a lower performance of Collectors 3 and 4 compared to their original performances after construction …

The Future Of Groundwater In California: Lessons In Sustainable Management From Across The West, Christina Hoffman Babbitt, Katherine E. B. Gibson, Scott Sellers, Nicholas Brozovic, Anthony Saracino, Ann Hayden, Maurice Hall, Sandi Zellmer

Daugherty Water for Food Global Institute: Faculty Publications

The 2014 Sustainable Groundwater Management Act (SGMA) created, for the first time and on an unprecedented scale, a mandate to change how groundwater is managed statewide in California. While enacting SGMA was a tremendous step forward, communities and water districts now face the considerable challenge of creating successful groundwater management programs. This report is aimed at helping California’s water managers, public water agencies, county commissioners, city planners, and others better understand the suite of tools and approaches that can be used to enhance the sustainable management of groundwater. Specifically, we consider four categories of management tools—regulatory, incentive-based, agency supply augmentation …

Environmental Studies 129: Water Policy In The Western U.S., Costanza Rampini

Faculty Publications, Environmental Studies

Water, or lack of it, is the defining characteristic of development in the Western United States. Using multiple analytical frameworks, including history, law, economics, environmental science, and sociology, we will investigate the interrelationships of key policies, players, and projects involved in Western water. More specifically, we will critically examine how important federal, state, and local water policies arose and how they affect different stakeholder groups (e.g., irrigators, environmentalists, indigenous peoples, the local citizenry, government entities, public water resource agencies). We will also learn about how stakeholder values and corresponding water policies have changed, or failed to change, over time. Case …

Cholera: Uganda, Emilie Verran

Global Issues in Public Health

The bacterium Vibrio cholerae, when ingested, infects the intestines and causes a communicable diarrhea disease called cholera. Outbreaks of cholera occur in areas with poor sanitation and sewage treatments where fecal material of an infected person contaminates the water. These areas include Southeast Asia, Haiti, and sub-Saharan Africa, including Uganda. From 2011-2016, an analysis of Ugandan cholera data showed ‘hot spots’ of cholera cases in fishing communities with incidence rates as high as 120-998 cases per 100,000 people. An analysis of these same districts from 2011-2015 showed an average Case-Fatality Ratio of 2.4%, with the worst district as high …

Water Scarcity: Sudan, Catherine Priebe

Global Issues in Public Health

Water scarcity is an environmental global problem that will only become more pressing as time goes on. It is a public health issue that affects every continent, although certain areas of the world are facing more serious water scarcity than others such as Sudan. Populations that are more vulnerable to the effects of water scarcity are the poor, women, children, and those living in areas of political unrest. For example, South Sudan’s urban water systems have been damaged during recent warfare. Water scarcity is also an issue that disproportionately affects women who are forced from a young age to travel …

Muddy Waters: Refining The Way Forward For The “Sustainability Science” Of Socio-Hydrogeology, Paul Hynds, Shane Regan, Luisa Andrade, Simon Mooney, Kevin O'Malley, Stephanie Dipelino, Jean O'Dwyer

Articles

The trouble with groundwater is that despite its critical importance to global water supplies, it frequently attracts insufficient management attention relative to more visible surface water sources, irrespective of regional climate, socioeconomic profile, and regulatory environment. To this end, the recently defined sub-discipline of "socio-hydrogeology", an extension of socio-hydrology, seeks to translate and exchange knowledge with and between non-expert end-users, in addition to involving non-expert opinion and experience in hydrogeological investigations, thus emphasising a "bottom-up" methodology. It is widely acknowledged that issues pertaining to groundwater quality, groundwater quantity, climate change, and a poor general awareness and understanding of groundwater occurrence …

Weathering Climate Change: Provisions For Climate Change Resiliency In Transboundary River Treaties, Emily Joan Zmak

Electronic Theses and Dissertations

Climate change will be most apparent in alterations to the hydrologic system - shifts in movement, variations in extremes - thereby defining many resource disputes in the coming decades. Water is a boundaryless resource; as its hydrologic patterns shift within and without borders, so too will preexisting agreements on its use and allocation. The question for transboundary water agreements is: how can agreements both satisfy parties' needs and account for future uncertainties of climate-induced changes to their basins' hydrologic systems?

From examining literature and water agreements, this thesis develops a list of provisions identified as foundational to resiliency in transboundary …

Drought And Land-Cover Conditions In The Great Plains, Heather Tollerud, Jesslyn Brown, Thomas Loveland, Rezaul Mahmood, Norman Bliss

High Plains Regional Climate Center: Staff Publications

Land–atmosphere interactions play a critical role in the Earth system, and a better understanding of these interactions could improve weather and climate models. The interaction among drought, vegetation productivity, and land cover is of particular significance. In a semiarid environment, such as the U.S. Great Plains, droughts can have a large influence on the productivity of agriculture and grasslands, with serious environmental and economic impacts. Here, we used the vegetation drought response index (VegDRI) drought indicator to investigate the response of vegetation to weather and climate for landcover types in the Great Plains in the United States from 1989 to …

Thermal Tolerance Limits Of The Chinese Mystery Snail (Bellamya Chinensis): Implications For Management, Jessica L. Burnett, Kevin L. Pope, Alec Wong, Craig R. Allen, Danielle Haak, Bruce J. Stephen, Daniel R. Uden

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The Chinese mystery snail, Bellamya chinensis (Gray, 1834) is a gastropod native to East Asia and is considered an invasive species in North America where its impacts on native species and ecosystems are not well understood. Scientific literature describing its biology and life history are sparse. Thermal tolerance limits, or the maximum and minimum temperature under which a species can survive, are key to identifying the potential geographical range of a species. The ability of managers to control invasive species is directly impacted by the thermal tolerance limits of a species. We attempted to identify the thermal tolerance limits of …

The Effect Of Size On Juvenile Green Sturgeon (Acipenser Medirostris) Behavior Near Water-Diversion Fish Screens, Jamilynn B. Poletto, Dennis E. Cocherell, Natalie Ho, Joseph J. Cech Jr., A. Peter Klimley, Nann A. Fangue

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Anthropogenic water management projects and facilities that alter the local and regional hydrology of riverine environments greatly influence the behavior, physiology, and survival of native fishes. To mitigate for losses of native fishes at these structures, many are outfitted with fish-exclusion screens to reduce entrainment. The effect of fish size and age on behavior near fish screens, however, is largely unknown. Therefore, we tested two size classes of juvenile green sturgeon (Acipenser medirostris; small, early juveniles: 9.2 ± 0.2 cm fork length [FL], 6.9 ± 0.3 g; intermediate juveniles: 18.8 ± 0.2 cm FL, 36.9 ± 0.8 g) …

Resilience In Environmental Risk And Impact Assessment: Concepts And Measurement, David G. Angeler, Craig R. Allen, Ahjond S. Garmestani, Kevin L. Pope, Dirac L. Twidwell Jr, Micro Bunschuh

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Different resilience concepts have different assumptions about system dynamics, which has implications for resilience-based environmental risk and impact assessment. Engineering resilience (recovery) dominates in the risk assessment literature but this definition does not account for the possibility of ecosystems to exist in multiple regimes. In this paper we discuss resilience concepts and quantification methods. Specifically, we discuss when a system fails to show engineering resilience after disturbances, indicating a shift to a potentially undesired regime. We show quantification methods that can assess the stability of this new regime to inform managers about possibilities to transform the system to a more …

Agroecology For The Shrinking City, Dustin L. Herrmann, Wen-Ching Chuang, Kristen Schawrz, Timothy M. Bowles, Ahjond S. Garmestani, William D. Shuster, Tarsha Eason, Matthew E. Hopton, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Many cities are experiencing long-term declines in population and economic activity. As a result, frameworks for urban sustainability need to address the unique challenges and opportunities of such shrinking cities. Shrinking, particularly in the U.S., has led to extensive vacant land. The abundance of vacant land reflects a loss of traditional urban amenities, economic opportunity, neighbors, businesses, and even basic city services and often occurs in neighborhoods with socially and economically vulnerable or underserved populations. However, vacant land also provides opportunities, including the space to invest in green infrastructure that can provide ecosystem services and support urban sustainability. Achieving desirable …
