Building And Characterizing A Lab-Scaled Aquifer Storage And Recovery System, Murat Can Kayabas

USF Tampa Graduate Theses and Dissertations

To use Aquifer Storage and Recovery (ASR) as a water treatment and storage method, we must understand the fate and behavior of potential contaminants in the system. Knowing more about the aquifer properties such as dispersivity will enable us to assess how the target chemicals behave in the system. Characterizing the aquifer by using a tracer is a good way to estimate dispersivity since the tracer is not adsorbed or degraded. This study aims to build a lab-scale physical model of a confined aquifer to simulate an ASR system, verify its hydraulic functionality, and characterize the hydraulics of the aquifer …

Assessment Of Water Availability In The Osage Nation Using An Integrated Hydrologic-Flow Model, Jonathan (Jp) Traylor, Shana L. Mashburn, Randall T. Hanson, Steven M. Peterson

United States Geological Survey: Water Reports and Publications

Document abstract

The Osage Nation of northeastern Oklahoma, conterminous with Osage County, covers about 2,900 square miles. The area is primarily rural with 62 percent of the land being native prairie grass, and much of the area is used for cattle ranching and extraction of petroleum and natural gas. Protection of water rights are important to the Osage Nation because of its reliance on cattle ranching and the potential for impairment of water quality by petroleum extraction. Additionally, the potential for future population increases, demands for water from neighboring areas such as the Tulsa metropolitan area, and expansion of petroleum …

Encapsulated Chitosan-Modified Magnetic Carbon Nanotubes For Aqueous-Phase Crvi Uptake, Mian Muhammad-Ahson Aslam, Walter Den, Hsion-Wen Kuo

Water Resources Science and Technology Faculty Publications (Archived)

This work demonstrates the performance of a composite adsorbent encapsulated with chitosan (CS) and maghemite-doped multiwall carbon nanotubes (MWCNTs). Hexavalent chromium (Cr^VI) was used as the representative hazardous heavy metal to characterize the adsorption behavior of the composite beads. The chromium speciation chemistry combined with the chitosan surface chemistry rendered pH at 4 to be the optimized condition in which the uptake of Cr^VI was quantitatively most effective. The Langmuir isotherm with a maximum adsorption capacity of 119 mg g⁻¹ at 298 K was observed. The Cr^VI adsorption studies using partial compositions of the beads …

The Drought Monitor Comes Of Age, Brad Rippey, Brian Fuchs, David Simeral, Deborah J. Bathke, Richard R. Heim Jr., Mark Svoboda

National Drought Mitigation Center: Faculty Publications

The 20th century featured immense scientific discoveries and advances. Astrophysics gained Einstein’s life-altering theory of relativity, opening the door to nuclear weaponry and the mind-bending Big Bang theory. The medical field achieved stunning success in suppressing or vanquishing a host of deadly diseases, including polio and smallpox. And through advances in computing technology, meteorological forecasting moved from back-of-the-envelope calculations to supercomputers. However, drought monitoring fell behind the curve of scientific advancement. Not until 1965, when the United States Department of Commerce published Wayne C. Palmer’s “Research Paper No. 45: Meteorological Drought,” was there even a complex mathematical definition of drought. …

Flash Drought Onset Over The Contiguous United States: Sensitivity Of Inventories And Trends To Quantitative Definitions, Mahmoud Osman, Bejamin F. Zaitchik, Hamada S. Badr, Jordan I. Christian, Tsegaye Tadesse, Jason A. Otkin, Martha C. Anderson

National Drought Mitigation Center: Faculty Publications

The term “flash drought” is frequently invoked to describe droughts that develop rapidly over a relatively short timescale. Despite extensive and growing research on flash drought processes, predictability, and trends, there is still no standard quantitative definition that encompasses all flash drought characteristics and pathways. Instead, diverse definitions have been proposed, supporting wide-ranging studies of flash drought but creating the potential for confusion as to what the term means and how to characterize it. Use of different definitions might also lead to different conclusions regarding flash drought frequency, predictability, and trends under climate change. In this study, we compared five …

Distribution And Antibiotic Resistance Profiles Of Salmonella Enterica In Rural Areas Of North Carolina After Hurricane Florence In 2018, Yuqing Mao, Mohamed Zeineldin, Moiz Usmani, Sital Uprety, Joanna Shisler, Antarpreet Jutla, Avinash Unnikrishnan, Thanh H. Nguyen

Civil and Environmental Engineering Faculty Publications and Presentations

The frequency and magnitude of extreme events are increasing globally (Arnell & Gosling, 2016). Inundation, as a result of massive flooding, has the potential to change environmental conditions abruptly, and as a result, add pressure to the metabolism and proliferation of microorganisms (Furtak et al., 2020). The resulting overland flows and additional burden from domestic sewer and septic tank systems during an extreme flood event can introduce pathogens into ecologically unstable water bodies. For example, Yu et al. (2018) reported elevated levels of Escherichia coli and antibiotic resistance genes (ARGs) in river water samples 6 months after flooding in Houston, …

Coastal Watershed Monitoring And Management: Geomorphology, Geochemistry, And Hydrologic Modeling Of Los Peñasquitos Creek, Ca, Ravleen Khalsa-Basra

Theses

Rivers in semi-arid climates are directly influenced by local geographic and hydrologic conditions and impacted by modifications to hydrology via urbanization. Changes can influence erosion, morphology, habitat sustainability, and watershed health. In highly urbanized southern California coastal regions, these rare open spaces provide vital ecosystem services. Los Peñasquitos Creek in San Diego County is one such watershed. Using stream surveying and laboratory methods we quantified channel characteristics, grain size distribution, total metal concentration [M], organic carbon (%OC), and phosphate to longitudinally characterize the creek for improved management. Results identified three distinct reaches in the watershed (upper, middle, lower). Downstream, depth …

Watershed Sciences Faculty Publications

Despite increasing evidence that large northern lakes are rapidly changing due to climate change, descriptive baseline studies of their physicochemical properties are largely lacking, limiting our ability to detect or predict change. This study represents a comprehensive scientific assessment of the limnology of Yukon’s largest lake: Lhù’ààn Mân’ (Kluane Lake), an important waterbody for local and First Nation communities, and key habitat for trout and salmon. Water sample and instrument data generated throughout 2015 describe distinct regions within the lake and their respective seasonal variability. A deep, glacially-influenced southern basin was characterized by cold, turbid, poorly stratified, unproductive, and nutrient-poor …

A Continental-Scale Assessment Of Density, Size, Distribution And Historical Trends Of Farm Dams Using Deep Learning Convolutional Neural Networks, Martino E. Malerba, Nicholas J. Wright, Peter I. Macreadie

Climate Science Research Articles

Farm dams are a ubiquitous limnological feature of agricultural landscapes worldwide. While their primary function is to capture and store water, they also have disproportionally large effects on biodiversity and biogeochemical cycling, with important relevance to several Sustainable Development Goals (SDGs). However, the abundance and distribution of farm dams is unknown in most parts of the world. Therefore, we used artificial intelligence and remote sensing data to address this critical global information gap. Specifically, we trained a deep learning convolutional neural network (CNN) on high-definition satellite images to detect farm dams and carry out the first continental-scale assessment on density, …

Valuation Of Drought Information: Understanding The Value Of The Us Drought Monitor In Land Management, Tingting Liu, Richard Krop, Tonya Haigh, Kelly Helm Smith, Mark D. Svoboda

National Drought Mitigation Center: Faculty Publications

Droughts affect recreation and tourism, grazing, forests, and timber, and can have important indirect effects for the ecosystems and species that rely on water. Despite its importance, the effect of drought in the land management sector is less understood than in other water-intensive sectors, such as agriculture and public water supplies. This study presents the first-ever estimates of the economic valuation of the information provided by the U.S. Drought Monitor using the avoided cost method. These estimates are based on the time and labor saved by using the U.S. Drought Monitor rather than compiling drought-related information from other sources, or …

Moving Beyond ‘More Crop Per Drop’: Insights From Two Decades Of Research On Agricultural Water Productivity, Meredith Giordano, Susanne M. Scheierling, David O. Tréguer, Hugh Turral, Peter G. Mccornick

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.

Ranchers’ Use Of Drought Contingency Plans In Protective Action Decision Making, Tonya Haigh, Michael Hayes, Jolene Smyth, Linda Stalker Prokopy, Charles A. Francis, Mark Burbach

National Drought Mitigation Center: Faculty Publications

Drought contingency planning is an increasingly common tool in the ranchers’ climate adaptation toolboxes, but its effect on drought response has not yet been evaluated. We use cognitive models of protective action decision making and planning to explore the effects of having a drought plan on the use of drought early warning information and drought response (and timing). Results of a cross-sectional, probability-based survey of livestock producers affected by a 2016 flash-drought are used to describe the characteristics of operations with drought plans and provide evidence of whether having a plan predicts drought information use and response. While larger operations …

Wastewater Treatment Plant’S Effectiveness At Treating Fecal Coliforms On The Lower Kanawha River, Christina Elaine Whitt

Theses, Dissertations and Capstones

The treatment of household waste and water via wastewater treatment plants is an extremely important process that helps to keep humans and animals healthy and safe (Environmental Protection Agency, 2019). With so many ways to treat wastewater, it is difficult to know which treats most effectively. Most treatment is done through the introduction of air which serves to evenly distribute oxygen for aerobic biodegradation in the wastewater. The effectiveness of the treatment is directly related to the process upon which air is introduced. The different ways of injecting air into the treatment process makes a significant difference in treatment outcome. …
