Landscape/Atmosphere Interactions And Carbon-Dioxide Dynamics In The Great Onyx Groundwater Basin, Mammoth Cave National Park, Kentucky, Meghan Raines
Masters Theses & Specialist Projects
An increase in atmospheric CO2 since the Industrial Revolution has altered rates of global climate change and has motivated a need to better quantify the flux of carbon between Earth’s reservoirs. Attempts to quantify the exchange of atmospheric carbon between sources and sinks have led to an increasing interest in the terrestrial landscape, including the continental carbon sink associated with carbonate-mineral dissolution. This research sought to better inform an understanding of karst landscapes and their relationship with global climate change through carbon cycling. The study utilized high-resolution data collection of pH, temperature, and specific conductance of waters in the Cascade …
A Predictive Flood Model For Urban Karst Groundwater Systems, Trayson Lawler
A Predictive Flood Model For Urban Karst Groundwater Systems, Trayson Lawler
Masters Theses & Specialist Projects
Urban karst environments are often plagued by groundwater flooding, which occurs when water rises from the subsurface to the surface through the underlying caves and other karst features. The heterogeneity and interconnectedness of karst systems often makes them very unpredictable, especially during intense storm events; urbanization exacerbates the problem with the addition of many impervious surfaces. Residents in such areas are frequently disturbed and financially burdened by the effects of karst groundwater flooding. The Federal Emergency Management Agency (FEMA) offers limited protection to citizens living near flood-prone areas as they primarily focus on the areas near surface bodies of water. …

Western Kentucky University Stormwater Utility Survey 2023, Warren Campbell, Emily G. Davis
SEAS Faculty Publications
The main goal of this survey is to identify as many U.S. Stormwater Utilities (SWUs) as possible. Because many stormwater professionals do not have the time to respond to questionnaires, our primary method of identification was Internet searches. We searched key terms such as “stormwater utility”, “stormwater fee”, and “drainage fee”. We scoured online municipal codes such as Municode, AmLegal, Sterling, LexisNexis, General Code, and others. We searched through many city web websitesing to find utilities. We have also had many people contact me to update fees and identify new utilities. However, the data primarily comes from Internet sources and …

Alfred Russel Wallace Notes 25. Wallace And The 'Physical Environment'., Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace’s natural selection essay of 1858 has been held to frame a greater role for the physical environment in forcing selection regimes than we find in Darwin’s writings, but here that verdict is challenged by a re-examination of both the essay itself, and period usage of the term ‘physical.’

Comparison Of Groundwater Chemistry And Associated Biodiversity Of Sulfidic Karst Habitats In Southcentral Kentucky, Kendall Wheeler
Comparison Of Groundwater Chemistry And Associated Biodiversity Of Sulfidic Karst Habitats In Southcentral Kentucky, Kendall Wheeler
Mahurin Honors College Capstone Experience/Thesis Projects
In most ecosystems, primary production is conducted by plants or photosynthetic microbes; however, extremophilic sulfur-oxidizing bacteria can use hydrogen sulfide gas (H2S) as an electron donor to produce metabolic energy in a type of metabolism called chemoautotrophy. These ecosystems are a prominent feature of some karst landscapes, and two have been observed in the Mammoth Cave system, Sulphur River in Parker Cave and Marianne’s Pass in Mammoth Cave National Park respectively.
Sulfidic water is ubiquitous in southcentral Kentucky and is strongly associated with hydrocarbon deposits. This oil boom of the 1880s in this region predates most environmental regulation and records …
Factors Influencing Tree Growth In A Bottomland Hardwood Along The Green River In Kentucky, Caleb Miller
Factors Influencing Tree Growth In A Bottomland Hardwood Along The Green River In Kentucky, Caleb Miller
Masters Theses & Specialist Projects
In bottomland hardwood forests, large fluctuations in moisture availability can lead to stress from both flooded and drought conditions. These forests can have a complex species composition with different water use and drought strategies. The bottomlands in which these species co-occur can have a complex spatial distribution of alluvial sediments due to the meandering and migration of river or stream channels, which may impact the hydrology, nutrient dynamics, and productivity. At Western Kentucky University's Green River Preserve, approximately 9 ha of bottomland hardwood forest were planted in 2006. Although these hardwoods have received equal amounts of sunlight, rainfall, and wind, …

Investigating Epikarst Recharge Dynamics Under Agricultural Landuse Using Hydrometeorological And Isotopic Tracers, Austin Shane Deering
Masters Theses & Specialist Projects
Epikarst systems have complex recharge – discharge processes in telogenetic karst systems, including highly variable storage, flowpaths, and mixing dynamics. This research aimed to characterize the epikarst zone using hydrogen and oxygen isotopic tracers of these processes within south-central Kentucky’s Crumps Cave system located in the Pennyroyal Sinkhole Plain. Data and statistical analyses were applied to highresolution rainfall (RF), lysimeter (10 cm, 20 cm, 30 cm depths), and an epikarst Waterfall 1 (WF1) isotope data collected on a weekly basis between 2011-2018. These data were coupled with WF1 discharge measurements and weather station data collected at Crumps Cave Preserve during …

Answers In The East: An Examination Of China's Renewable Energy And Its Application To Central Appalachia, Lillian Hamm
Answers In The East: An Examination Of China's Renewable Energy And Its Application To Central Appalachia, Lillian Hamm
Mahurin Honors College Capstone Experience/Thesis Projects
While much of China’s electrification has depended on coal, recent decades illustrate the country is heavily investing in and implementing renewable energy as a power source. Even China’s coal-rich provinces, like the northeastern province of Shanxi, have been making the transition to renewable energy. The central Appalachian states comprised of eastern Kentucky, West Virginia, western Virginia, and northeastern Tennessee share many characteristics with China’s Shanxi province including economic resources, climate, and geography. Yet, central Appalachia has not been able to easily transition to renewable energy. However, there are various cultural, political, and technological differences between the two regions to explain …

Quantifying Tekeze River Canyon Incision On The Ethiopian Plateau From Low-Temperature Apatite Thermochronology, Jacob Thomas Grigsby
Masters Theses & Specialist Projects
The Ethiopian Plateau in East Africa features dynamic topography, deep river incision (~1.5 km), active tectonics, continental rifting, volcanic terrain and ~2 km of plateau uplift. Situated on the northwestern part of the Ethiopian Plateau, the Tekeze River is one of the two major rivers associated with incising and documenting the recent geologic history of the uplifted plateau landscape. The consequential Tekeze River incision into the uplifted Ethiopian Plateau is associated with the arrival and impingement of the Afar mantle plume as evidenced by the presence of thick sheets of Cenozoic flood basalts (~30 Ma). However, the Cenozoic to present-day …

Geochemical Flux Analysis Of Glacial River Runoff For Sólheimajökull, Iceland, Jessica Garrison
Mahurin Honors College Capstone Experience/Thesis Projects
Geochemical fluxes in aqueous studies are an essential component of research to understand weathering and changes in a hydrologic system. These data can indicate any discrepancies, outliers, or gradual changes in a water environment to gain information on pollutants, carbon cycles, biological input, etc. Glacial melt is the majority of the surface water present throughout the country. The melting amount is increasing with the temperatures, which can be monitored by the changes in geochemical flux during increased discharge in glacial rivers. A high-resolution data set of Sόlheimajökull Glacier in Iceland was used to determine how changing climatic conditions for the …
Application Of 3d Salt Modeling: An Example From The Northeastern Gulf Of Mexico, Adam Mattson
Application Of 3d Salt Modeling: An Example From The Northeastern Gulf Of Mexico, Adam Mattson
Masters Theses & Specialist Projects
Salt tectonics has important implications for hydrocarbon exploration in saltbearing basins since salt deformation can directly or indirectly form hydrocarbon traps, influence hydrocarbon migration, and can control deepwater depositional systems. In various basins around the globe, extensive research has been conducted on initiation of salt mobilization, subsequent deformation, and eventual cessation, mostly from subsurface two-dimensional (2D) sections. However, 3D seismic data has dominated the petroleum industry for the last 30 years. Despite the plethora of 3D seismic data acquired in salt-bearing basins, there has been hardly any published work on the 3D geometries of complex salt bodies. 3D salt mapping …
Influence Of Spring Flow Reversals On Cave Dissolution In A Telogenetic Karst Aquifer, Mammoth Cave, Ky, Chelsey Kipper
Influence Of Spring Flow Reversals On Cave Dissolution In A Telogenetic Karst Aquifer, Mammoth Cave, Ky, Chelsey Kipper
Masters Theses & Specialist Projects
An often overlooked connection between karst groundwater systems and surface water is spring flow reversal, the flow of river water into karst springs caused by changes in hydraulic gradient. Karst aquifers are subject to the intrusion of river water when the hydraulic head of a base level river is higher than the hydraulic head of a base level spring. When this occurs, the flow out of the spring reverses, allowing river water to enter base level conduits. River water thus becomes a source of recharge into karst basins, transporting both valuable nutrients and harmful contaminants into karst aquifers. The rapid …
The Effectiveness Of Mobile Eye-Tracking To Enhance Guided Show Cave Experiences, Jenna Michele Hammond
The Effectiveness Of Mobile Eye-Tracking To Enhance Guided Show Cave Experiences, Jenna Michele Hammond
Masters Theses & Specialist Projects
Karst terrains are landscapes with a distinctive hydrology and set of landforms that arise from a combination of high bedrock solubility and well-developed secondary (fracture) porosity. Karst areas are easily polluted due to the rapid transport of unfiltered percolating water through the systems. While many individuals are able to identify karst landforms such as sinkholes and caves, an understanding of the interconnectedness of the surface and subsurface in karst landscapes, as well as the vulnerability of karst areas to degradation, is often limited. Show caves, which are caves made accessible to visitation by humans through built infrastructure, can serve as …

Meteorological Comparison Of Three Cave Systems, Matthew Wine
Meteorological Comparison Of Three Cave Systems, Matthew Wine
Mahurin Honors College Capstone Experience/Thesis Projects
Cave systems are home to delicate underground ecosystems that can be affected by changes in surface atmospheric conditions which in turn affect underground meteorology. Modern human use of caves is typically for tourism, so understanding surface-underground weather-climate interactions is important when caves carry streams that are prone to flooding in response to surface precipitation. The purpose of this research is to document the effects of surface weather conditions on cave meteorology in three different cave system types located in different geographic locations including an island, the central USA, and at high elevations in British Columbia. The study caves include Kaumana …

Mass-Transport Deposits In The Northern Gulf Of Mexico And Their Implications For Hydrocarbon Exploration, Michael Raymond Arthur
Mass-Transport Deposits In The Northern Gulf Of Mexico And Their Implications For Hydrocarbon Exploration, Michael Raymond Arthur
Masters Theses & Specialist Projects
This study investigates Mio-Pliocene mass-transport deposits (MTDs) in an understudied, hydrocarbon-rich region of the northeastern Gulf of Mexico. The research utilizes a high-quality 3D seismic dataset with an area of 635 km2, along with wireline logs and biostratigraphic data. With the help of quantitative seismic geomorphology techniques, detailed mapping of MTDs suggests a complex erosional and depositional history. Deposition of a MTD unit resulted in a 180 m topographic high that substantially influenced the distribution and morphology of subsequent MTDs, specifically the bifurcation of later mass-transport flows. This bifurcation contributed to the generation of a non-shielded erosional remnant with an …
