An Introduction To Consumptive Use Of Water In South Carolina, Heather Bergerud Nix, Mani Rouhi Rad

Journal of South Carolina Water Resources

Effective water resource management requires understanding the supply of and the demand for water. In South Carolina, as in other places, water demand is often determined using total withdrawal volumes. However, the volume of water that is withdrawn can be significantly different from the volume that is actually consumed, which becomes unavailable for downstream uses. Water used for energy generation is commonly excluded from evaluations of total withdrawal volume because it is often assumed to be no or low consumptive use, meaning much of the withdrawn water is returned to the source and remains available for downstream uses. Additionally, energy …

Characteristics And Hydraulic Behavior Of Adsorptive Media For Use In Permeable Reactive Barriers, Shelby Rocha

USF Tampa Graduate Theses and Dissertations

The Cargill ditch is located on the property of Se7en Wetlands, a 1600-ac treatment wetland system in Lakeland, Polk County, Florida. The Se7en Wetlands property was previously utilized for phosphate mining prior to the construction of the system. Nonpoint nutrient sources derived from remnants of abandoned phosphate mines – known as “legacy phosphorus” – become mobilized by stormwater runoff and impair surface water bodies by promoting harmful algal blooms (HABs). Thus, the Cargill ditch likely conveys nutrient rich flow resulting from legacy phosphorus and is thought to be one contributing factor in the occurrence of HABs within the treatment wetland …

Impact Of Land Use/Cover Change And Slope Gradient On Soil Organic Carbon Stock In Anjeni Watershed, Northwest Ethiopia, Bethel Geremew, Tsegaye Tadesse, Bobe Bedadi, Hero T. Gollany, Kindie Tesfaye, Abebe Aschalew

National Drought Mitigation Center: Faculty Publications

Today’s agri-food systems face the triple challenge of addressing food security, adapting to climate change, and reducing the climate footprint by reducing the emission of greenhouse gases (GHG). In agri-food systems, changes in land use and land cover (LULC) could affect soil physicochemical properties, particularly soil organic carbon (SOC) stock. However, the impact varies depending on the physical, social, and economic conditions of a given region or watershed. Given this, a study was conducted to quantify the impact of LULC and slope gradient on SOC stock and C sequestration rate in the Anjeni watershed, which is a highly populated and …

Estimation Of Quantitative Genetic Parameters Of The Eastern Oyster (Crassostrea Virginica) In The Gulf Of Mexico, Heather King

Master's Theses

The decline of natural oyster reefs in Gulf of Mexico (Gulf) states has stimulated the development of aquaculture to support the industry and restoration programs. Gulf habitats feature diverse salinity environments that may require oysters bred for habitat-specific optimal genetic characteristics. In this work, genetic parameters for performance in habitats with different salinity were estimated. In September 2020, 102 males and 102 females sourced from 17 natural reefs across the northern Gulf were bred according to 2 males x 2 females non-overlapping factorial crossing designs, resulting in 204 full and half sibs. All families were pooled after fertilization according to …

The Flow Of Power: Addressing Asymmetric Flood Risk In The Upper Valley, Eric Vr Hryniewicz

Geography Undergraduate Senior Theses

Floods are the most damaging natural disasters in America. Land use change in upland watersheds can increase the probability and severity of floods (Bronstert, Niehoff, & Burger, 2002). When watersheds are divided by political and private property boundaries it leads to a misalignment of incentives in which downstream users lack recourse for upstream land use decisions contributing to flood risk. In this thesis, researchers interrogate the attributes of town officials and towns that determine what motivates town governments to act on flooding and what motivates and enables town officials to collaborate on planning and how do they collaborate in practice. …

Public-Ish, Aliah Werth

Masters Theses

Climate change affects public space, and architecture must establish tenets that prioritize pedestrians in this difficult era. Greywater re-use can be a mechanism for creating shade, and in turn, public space.

As heat waves grow more intense, the vast swaths of asphalt that connect commercial zones pose greater risks to public health and to urban vitality. This thesis records the typical material, spatial, and lived conditions of strip malls in urban heat islands, and demands more from infrastructure in public-ish space.

Heat violence weaves through Los Angeles’ built form. Parking space minimums, required setbacks, and height restrictions pull buildings away …

Spatial And Temporal Activity Patterns Among Sympatric Tree-Roosting Bat Species In An Agriculturally Dominated Great Plains Landscape, Christopher Fill, Craig R. Allen, John F. Benson, Dirac Twidwell

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

In agroecosystems, bats can provide a critical ecosystem service by consuming night-flying insect pests. However, many bats also face intense population pressures from human landscape modification, global change and novel diseases. To better understand the behavioral activity of different bat species with respect to space, time, habitat, and other bat species in this environment, we investigated species correlations in space and time over row crop agricultural fields. We used acoustic grids to document spatial and temporal co-occurrence or avoidance between bats and recorded eight species across the 10 field sites we sampled. All species significantly overlapped in two-dimensional space and …

Assessing Boil Water Notices As Health-Risk Communication: Risk Perceptions, Efficacy, And Compliance During Winter Storm Uri, Ashleigh M. Day, Sydney O'Shay, Khairul Islam, Matthew W. Seeger, Shawn P. Mcelmurry

Open Data at Wayne State

Winter Storm Uri was an extreme disaster that impacted much of the United States during February of 2021. Texas and Oklahoma were generally not prepared for such an event and experienced massive power grid failures. This led to cascading risks including water system disruptions and many boil water notices (BWNs). The breakdown of some communication channels and the inability to enact protective actions due to power outages, as well as travel limitations on public roads, complicated both dissemination and implementation. Under these conditions, a non-representative, cross-sectional, survey was collected to assess individuals experience BWNs and how perceived efficacy impacts compliance. …

Indigenous Water Justice: Theory, Gaps, And Opportunities For Application, Ruby Howard

University Honors Theses

Indigenous people are particularly at risk of water scarcity in the U.S. and abroad, and face high rates of nonexistent or failing water infrastructure, water pollution, pipeline proposals that threaten water resources, and water-related climate change impacts. They also are often unequipped, politically and economically, to react and adapt to these impacts, resulting in devastating health impacts. Due to this widespread insecurity, many scholars are calling for the application of a theory and set of principles known as water justice. However, Indigenous people have pointed out that water justice literature does not focus enough on Indigenous issues, often neglecting the …

Biopolymer-Coated Magnetite Nanoparticles For The Removal Of Emerging Contaminants From Aqueous Solutions, Hebatullah Farghal

Theses and Dissertations

Abstract

Biopolymers are gaining interest as promising materials for water purification due to their functionality, biodegradability, abundance, and safe use. In this work, three biopolymer-based systems were developed as adsorbents for removing emerging contaminants from water. The first system of biopolymeric nanocomposites was synthesized by coating chitosan/xylan biopolymeric nanocomposites on magnetite nanoparticles (CsXM) to facilitate their separation from water via a magnetic field. The prepared mesoporous CsXM nanocomposite was thermally stable and possessed a particle size of 11 nm and a neutral to slightly negative charge over the studied pH range of about 3 to 10. The nanocomposite efficiently removed …

Sustainability Analysis: Large-Scale Desalination Implications For Coastal California, Elizabeth H. Whitford

Master's Projects and Capstones

In response to prolonged drought, desalination is gaining popularity as an alternative water production method for fresh water. However, water desalting technology poses concerns; the process is energy intensive, creates brine waste, and has the potential to damage sensitive coastal ecosystems. Significant research is available on the technological, economic, and energy efficiency aspects of desalination, while only a small percentage of the current literature focuses on environmental impacts. This research analyzes the desalination literature holistically in terms of both energy consumption and environmental impacts by conducting 1) a historical and current state review of the sector, 2) a technology analysis …

Desal In So. Cal - Are We There Yet?, Luke F. Swanson

Master's Projects and Capstones

Southern California has access to a finite amount of water that is vulnerable to the state’s changing climate and growing population. The increasing population’s water demands and hydrologic variability due to climate change inspire different proposals to solve these water limitations. Seawater or brackish water desalination and wastewater recycling are all water resources that have the potential to help meet the water needs of Southern California, specifically the South Coast Hydrologic Region. Every water resource requires energy to transport, treat, and distribute the water for use; in an era of climate change, when energy use contributes to greenhouse gases, utilities …
