Arkansas Water Resources Center Technical Reports
Nonpoint source pollution associated with human land use (agriculture and urbanization) is one of the leading causes of impairment to waterways in the United States (EPA, 2000). The primary pollutants associated with agricultural and urban land use are sediment and nutrients which enter nearby streams during rain events and are then carried downstream. These sediments and nutrients may result in water quality issues in the downstream water bodies like increased algal growth or decreased water clarity (e.g. Smith et al., 1999).

Drought is an extreme climate phenomenon that happens slowly and periodically threatens the environmental and socio-economic sectors. Iraq is one of the countries in the Middle East that has been dealing with serious drought-related issues in the 21st century. Here, we investigate meteorological drought across Iraq from 1948 to 2009 at 0.25° spatial resolution. The Standardized Precipitation Evapotranspiration Index (SPEI) has been utilized as a multi-scalar drought index accounting for the effects of temperature variability on drought. Four of the main characteristics of drought including extent, intensity, frequency and duration are studied and the associated spatiotemporal patterns are investigated for …

Civil and Environmental Engineering Faculty Publications and Presentations
This study presented the conceptual framework of the water-management analysis module (WMAM) to derive effective physical specifications for the design and planning of low-impact development (LID) practices using the storm-water management model (SWMM). 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 …
Social Position Influencing The Water Perception Gap Between Local Leaders And Constituents In A Socio-Hydrological System, Melissa Haeffner, Douglas Jackson-Smith, Courtney G. Flint
Social Position Influencing The Water Perception Gap Between Local Leaders And Constituents In A Socio-Hydrological System, Melissa Haeffner, Douglas Jackson-Smith, Courtney G. Flint
Environmental Science and Management Faculty Publications and Presentations
How well city leaders represent their constituents and meet their needs are key concerns in transitioning to local sustainable water governance. To date, however, there is little research documenting the influence of social position between elected leaders who make policy, career staff water managers who design and operate systems and implement policies, and the members of the public whose individual water use behaviors are important drivers of water sustainability outcomes. In this study, we ask: ‘‘How does social position explain variation in water perceptions and concerns between different actors in a sociohydrological system?’’ Using a mixed method approach with survey …

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
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 …

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
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 …

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
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 …

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) …

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 …

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 …

A four-decade dataset (1974–2013) of 107,823 nitrate samples in 25,993 wells from western and eastern parts of Nebraska was used to assess long-term trends of groundwater nitrate concentration and decadal changes in the extent of groundwater nitrate-contaminated areas (NO3-N≥10 mg N/L) over the entire state. Spatial statistics and regressions were used to investigate the relationships between groundwater nitrate concentrations and several potential natural and anthropogenic factors, including soil drainage capacities, vadose zone characteristics, crop production areas, and irrigation systems. The results of this study show that there is no statistically significant trend in groundwater nitrate concentrations …
Using Drones In Agriculture
Daugherty Water for Food Global Institute: Administrative Materials
Unmanned aerial vehicles, known as “drones,” are increasingly popular for capturing aerial images. The United States Federal Aviation Administration eased their regulations for drone flights in June 2016, making drones more accessible for common use. Drones may supplement pre-existing imaging technology (e.g. satellites, manned aircraft, etc.). One case study in Nebraska found a niche application for drones. The participating producer used manned aerial imagery to identify potential problem spots in his fields. Then he used GPS navigation to direct the drone to more closely inspect the identified potential problem spots. This way the drone is not tasked with scouting entire …
Wireless Communications In Rural Areas
Wireless Communications In Rural Areas
Daugherty Water for Food Global Institute: Administrative Materials
In many rural farming communities across America, wireless internet connectivity is a luxury. Absence of quality connectivity directly affects the adoption of new agricultural technologies, many of which require high-speed wireless connectivity to provide producers with accurate, real-time analytics. The current environment of spotty wireless internet connectivity in some rural areas negatively affects innovation and entrepreneurship in agriculture. In interviews with Nebraska farmers about internet-based technology, of the two farmers provided opposing views on connectivity. One young farmer said he avoids using precision agriculture technologies that run on wireless connectivity because his rural area lacks reliable service. He even talked …
Soil Moisture Probes
Daugherty Water for Food Global Institute: Administrative Materials
Just like fuel gauges monitor fuel levels in a gas tank, soil moisture sensors monitor moisture levels in the soil. Irrigating without using soil moisture sensors is similar to driving without a fuel gauge: you’re likely to be overcautious to ensure you get to where you’re going! Soil moisture probes are designed to estimate soil volumetric water content based on the dielectric constant of the soil. The dielectric constant can be thought of as the soil’s ability to transmit electricity. The dielectric constant of soil increases as the water content of the soil increases, since the dielectric constant of water …

One in nine people goes to bed hungry each night, according to the U.N. World Food Program. That’s 795 million people on the planet who do not have access to enough nutritious food. The challenge is growing. Global drivers like climate change, urbanization and increasing demand for water-intensive agricultural products are altering landscapes, increasing soil erosion, and degrading water resources and soils in important food producing regions around the world. We must figure out how to feed a global population projected to reach 10 billion by 2050, with the same amount of water and arable land – and quickly. This …
