A Connectivity Framework To Explore The Role Of Anthropogenic Activity And Climate On The Propagation Of Water And Sediment At The Catchment Scale, Christos Giannopoulos
Doctoral Dissertations
Anthropogenic disturbance in intensively managed landscapes (IMLs) has dramatically altered critical zone processes, resulting in fundamental changes in material fluxes. Mitigating the negative effects of anthropogenic disturbance and making informed decisions for optimal placement and assessment of best management practices (BMPs) requires fundamental understanding of how different practices affect the connectivity or lack thereof of governing transport processes and resulting material fluxes across different landscape compartments within the hillslope-channel continuum of IMLs. However, there are no models operating at the event timescale that can accurately predict material flux transport from the hillslope to the catchment scale capturing the spatial and …

Reinforcement Learning Policy Gradient Methods For Reservoir Operation Management And Control, Sadegh Sadeghi Tabas
Reinforcement Learning Policy Gradient Methods For Reservoir Operation Management And Control, Sadegh Sadeghi Tabas
All Theses
Changes in demand, various hydrological inputs, and environmental stressors are among issues that water managers and policymakers face on a regular basis. These concerns have sparked interest in applying different techniques to determine reservoir operation policy and improve reservoir release decisions. As the resolution of the analysis rises, it becomes more difficult to effectively represent a real-world system using traditional approaches for determining the best reservoir operation policy. One of the challenges is the “curse of dimensionality,” which occurs when the discretization of the state and action spaces becomes finer or when more state or action variables are taken into …

The Pandemic, Climate Change And Farm Subsidies, Allen H. Olson, Edward J. Peterson
Journal of Food Law & Policy
Many people believe that once the COVID-19 pandemic has passed, life will return to the way it was. This belief is both unrealistic and dangerous. It is unrealistic because the virus will be around for years if not indefinitely. The timeframe for the worst of the pandemic will depend on our ability to administer effective vaccines worldwide and the public’s willingness to accept continued social distancing in the meantime. The damage done to public health, the economy and individuals is already substantial and will get worse. Recovery will be slow and incomplete. The belief that life will return to the …

Natural resources commissioned reports
The Department of Primary Industries and Regional Development (DPIRD) in partnership with Water Corporation, working with Murdoch and Curtin universities, are looking at new options to improve farm water security in the wheatbelt of Western Australia.
Winter rainfall has declined since 2000 and dams, traditionally used for farm water supply, no longer provide sufficient or reliable water, especially after 1 to 2 below average years. Increasingly, groundwater supplies are being considered to supply farm needs, including those from fractured rock aquifers, with opportunities to desalinate to improve water quality.
This project undertook to review groundwater availability in fractured rock aquifers …
Mapping Plastic Pollution In The Amite Watershed, Louisiana, Gourav Divan
Mapping Plastic Pollution In The Amite Watershed, Louisiana, Gourav Divan
LSU Master's Theses
Microplastics have quickly emerged as a concerning pollutant in both freshwater and marine environments. Their recent discovery means that their impacts are still being studied, however, it is important to continuously monitor their concentrations. An important conduit of plastic pollution to marine environments are rivers and streams. Previous models have estimated the transport of plastics from land to sea in many parts of the world. Most of these models, however, have been conducted at coarse spatial resolutions that make it difficult to establish tractable management programs to minimize this impact. Here, a previously existing model was applied to model for …
Engineered Nanostructured Nitrogen-Doped Carbon Network (Ndc) Electrodes With Unprecedented Cycling Stability For Water Capacitive Deionization In Harsh Conditions, Soha Essam Anwar
Theses and Dissertations
Capacitive deionization (CDI) is a feasible low-cost desalination technique for low-to-medium (brackish) salinity water. However, cycling stability and regeneration of the CDI electrodes are the bottlenecks hindering the practical application of the technology on large scale. Oxidation of the electrodes during the sequential adsorption-desorption processes is one of the most challenging problems hindering their long-term cycling performance. Herein, we demonstrated the ability to design and fabricate exceptionally stable CDI electrodes via a one-pot pyrolysis protocol. The optimized pyrolysis of nitrogen-carbon precursors at different temperatures enabled the fabrication of carbon materials with a controlled amount nitrogen dopant (NDCs) with exceptional cycling …

Do Mitigated Wetlands Support Similar Small Mammal Communities As Natural Wetlands?, Krista Noe, Mack Frantz, Christopher T. Rota, Jim Anderson
Presentations
Wetlands provide many ecosystem services and play an important ecological role in wildlife communities. Although wetland mitigation is a standard tool to combat losses to natural wetlands, it is essential to understand if mitigated wetlands are truly replacing natural wetlands in their full capacity. Because one important role of wetlands is to provide habitat for wildlife communities, it is important to determine if these created or restored wetlands can foster a wildlife community that is similar to natural wetlands. One understudied taxa in the realm of wetland mitigation research is small mammals. Our objectives are to examine community composition, occupancy, …

Quantifying The Contribution Of Solid Precipitates To The Total Alkalinity In A Coal-Mine Discharge, Lili Lei, Dorothy Vesper
Presentations
Flocculates and precipitates from coal mine drainage (CMD) are an integral part of the geochemical setting in mining-impacted streams. The precipitates may be very small, amorphous, and, depending on their chemistry, play a role in the storage and release of alkalinity. To evaluate the potential impact of CMD-solids on alkalinity, we conducted various tests using model and natural solids. Laboratory measurements of alkalinity are operationally defined by a titration to a fixed pH. When the solid-solution mixtures were tested using the standard alkalinity measurement method, no alkalinity could be detected; however, a possible reason for that was that the standard …

UNLV Theses, Dissertations, Professional Papers, and Capstones
Urban population is expected to exceed 70% of the world’s total by the middle of the 21st century. Thus, growth in number as well as the sizes of the cities are certain in the near future. The urbanization rates will be much higher in the developing countries than the developed. Such phenomena are accompanied by conversion of land cover from its natural use to built up environment to accommodation growing population. Built up surfaces include road networks, buildings, parking lots and pathways. They are permanently impervious and hydrologically active surfaces. Large volume and discharges of runoff characterize impervious surfaces with …

Estimating Irrigation In Rice Fields With A Water Balance Approach, Kristen Trinh
Biological and Agricultural Engineering Undergraduate Honors Theses
Global food production must increase to meet the demand associated with increased population growth, so irrigation water use will continue to rise. Therefore, it is important to monitor water usage particularly when an irrigation flowmeter is unavailable. A field water balance was created for a selection of rice fields in East-central Arkansas under observation in 2018 and 2019. From those, irrigation inputs are deduced from the water balance alone. First, each field had sensors that collected water table level (WTL) data. Next, other water inputs and outputs such as precipitation and evapotranspiration (ET) were collected from two modeled sources. The …

Daugherty Water for Food Global Institute: Faculty Publications
Concern over increasing water scarcity has led to the introduction of the concept of agricultural water productivity and an emphasis on interventions to achieve ‘more crop per drop’. Yet, a strong debate continues on how the concept is to be defined and used. Drawing largely from the irrigation literature, the origins of the concept and its methodological developments are reviewed, and its use in applied work over two decades is discussed. Based on this analysis of conceptual and applied research, key insights into the concept’s contributions and limitations are presented, as well as opportunities for further refinements.

Dissolved arsenic typically results from chemical weathering of arsenic rich sediments and is most often found in oxidized forms in surface water. The mobility of arsenic is controlled by its valence state and also by its association with iron oxides minerals, the forms of which are both influenced by abiotic and biotic processes in aqueous environment. In this study, speciation methods were used to measure and confirm the presence of reduced arsenic species in the surface water of Frenchman creek, a gaining stream that crosses the Colorado- Nebraska border. Selective extraction analysis of aquifer and stream bed sediments shows that …
