INVESTIGATION OF THE HYDROLOGY, FLUVIAL GEOMORPHOLOGY, AND SEDIMENT TRANSPORT IN THE LAKE THUNDERBIRD WATERSHED IN CENTRAL OKLAHOMA
Dutnell, Russell (2015-05-08)As human population continues to rise, an ever increasing burden is being placed on earth’s water resources. Between 1950 and 2010, the world’s population increased from 2.6 billion to almost 7 billion, and the population ... -
Iron Transport and Removal Dynamics in the Oxidative Units of a Passive Treatment System
Oxenford, Leah (2016-12)Abstract Mine drainage is threat to water systems in legacy mining districts as elevated concentrations of dissolved iron, sulfate, and trace metals have an unmitigated impact on water quality. Changes in pH due to ... -
Microcosm assessment of natural processes affecting chemicals of emerging concern in secondary effluent
Thornton, Erin (2017-05)The fight for new water sources is over, reclaimed water is next. Currently, the City of Norman supports its water needs via Lake Thunderbird (LT) and the Central Oklahoma Aquifer System (COAS). In times of peak demand, ... -
Novel, low-cost aluminum (hydr)oxide based materials for fluoride-impacted drinking-water: Batch and column studies
Du, Junyi (2016-05)Simple aluminum (hydr)oxides and layered double hydroxides were synthesized using common chemicals and equipment by varying synthesis temperature, concentrations of extra sulfate and citrate, and metal oxide amendments. ... -
Performance and environmental impact assessment of agricultural waste-based sorbents for phosphorus recovery and reuse
Ding, Yifan (2023-05)Phosphorus is an essential resource, yet global phosphorous reserves are limited, and increasing quantity of high-grade ore is being mined and turned into fertilizers to meet the increasing demand of food. However, since ... -
Phosphorus, Iron and Trace Metal Interactions at the Sediment Layer-Water Column Interface: The Potential Role of Recovered Mine Drainage Residuals
Tang, Zepei (2020-05)Nutrient enrichment, eutrophication and harmful algal blooms are global environmental concerns. The study site, Grand Lake o’ the Cherokees (GLOC) located in northeast Oklahoma, experiences eutrophication due to excess ... -
Quantifying Solar-Powered Removal of Aqueous and Gaseous Sulfide in a Mine Water Passive Treatment System
Wall, Taylor (2018-12-14)Passive treatment systems can improve water quality for mine water discharges. However, some process units, like vertical flow bioreactors (VFBRs), may produce excess sulfide, which can be a source of nuisance odors and ... -
Response of native prey species to an exotic invasive predator: Ecology and evolution of inducible defenses
Kiehnau, Emily (2021-05-14)One of the most common and devastating human impacts on the world’s ecosystems is the introduction of non-native invasive species which can negatively impact agriculture, industry, human health, and the natural environment. ... -
The role of iron-reducing bacteria in the corrosion of carbon steel: a new microbiologically influenced corrosion mechanism
Hernandez Santana, Maria Alejandra (2021-12-18)It was not too long ago that the ability of microorganisms to capture energy by engaging in electron transfer reactions with extracellular solid materials was discovered. This discovery has shifted the paradigms regarding ... -
Soil Trace Metals Concentrations in A Mining Impacted Agricultural Watershed: Comparison of Analytical Methods, Geospatial Distribution, and Evaluation of Risk
Sikora, Amy (2018-05-11)This study investigated four aspects surrounding lead, zinc, and cadmium soil trace metals concentrations within a mining impacted watershed: (1) a comparison of three soil trace metal quantification methods relating ... -
SORPTION AND RELEASE OF NICKEL AND ZINC USING A MIXED ALGAE COMMUNITY COLLECTED FROM A MINE DRAINAGE PASSIVE TREATMENT SYSTEM
Fielding, Ellen (2017-05)Mine water from upwellings in Commerce Oklahoma is treated by the Mayer Ranch Passive Treatment System (MRPTS) to remove contaminants. The last treatment section of MRPTS is referred to as the polishing pond (also known ... -
The Spatial Distribution of, and Upland Impacts on, Playa Wetland Invertebrates
Bright, Eric (2015)Playa wetlands are a type of temporary wetland that are numerous in the Great Plains of the United States. Playa wetlands offer a unique habitat within semiarid grassland ecosystems. My research on the invertebrates of ... -
Subsidy intermediaries: the role of aquatic plants in storing and transferring resources from aquatic biogeochemical hotspots to terrestrial ecosystems
Lopez, Jonathan (2022-05-13)The roles mobile animals and abiotic processes play as vectors for resource transfers between ecosystems (subsidies) are well-studied. Trophic interactions between mobile animals and their food sources often convey subsidies ... -
Synthesis and Characterization of Porous Hydroxyapatite Ceramics for Batch and Column Treatment of Fluoride-Impacted Ground Water
Nijhawan, Anisha (2019-05-10)Nearly 200 million people worldwide are exposed to drinking water with elevated levels of naturally occurring fluoride. The World Health Organization recommends a maximum fluoride concentration of 1.5 mg/L in drinking water ... -
Temporal and Spatial Variations in Sediment Trace Metal Concentrations in Streams, Rivers, and a Reservoir near a Derelict Lead-Zinc Mining District
Folz, Carlton (2021-05)Historic lead and zinc mining in the Tri-State Mining District has ceased, but the legacy of trace metal contamination (Cd, Cu, Ni, Pb, and Zn) throughout the region still exists. This thesis focuses on stream sediments ... -
Theoretical and Empirical Studies on Hierarchical Effects of Size Distributions: Linking the Individual to its Community
Hartnett, Rachel Nicole (2017-12)Population and community ecologists often view the world differently based on one assumption: community ecologists often assume that individuals within a population are functionally equivalent; population ecologists focus ... -
