Fractal Location And Anomalous Diffusion Dynamics For Oil Wells From The Ky Geological Survey, Keith Andrew, Karla M. Andrew, Kevin A. Andrew
Fractal Location And Anomalous Diffusion Dynamics For Oil Wells From The Ky Geological Survey, Keith Andrew, Karla M. Andrew, Kevin A. Andrew
Physics & Astronomy Faculty Publications
Utilizing data available from the Kentucky Geonet (KYGeonet.ky.gov) the fossil fuel mining locations created by the Kentucky Geological Survey geo-locating oil and gas wells are mapped using ESRI ArcGIS in Kentucky single plain 1602 ft projection. This data was then exported into a spreadsheet showing latitude and longitude for each point to be used for modeling at different scales to determine the fractal dimension of the set. Following the porosity and diffusivity studies of Tarafdar and Roy[1] we extract fractal dimensions of the fossil fuel mining locations and search for evidence of scaling laws for the set of deposits. The …
Heirloom And Hybrid Tomato Yield And Quality In Organic And Conventional Production Systems, Diana J. Edlin
Heirloom And Hybrid Tomato Yield And Quality In Organic And Conventional Production Systems, Diana J. Edlin
Masters Theses & Specialist Projects
Due to the recent changes in the economy of Kentucky tobacco production, some producers are seeking an alternative crop that will provide similar economic gains to tobacco without needing more acreage. Tomatoes are an existing crop in Kentucky that have been declining in acreage over the last five years. There is evidence to suggest that, through niche and local marketing, tomatoes may be able to fill the void left by tobacco. However, there is concern among producers that they will lose yield and/or quality if they switch to one of these niche production systems or cultivars.

Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham
Masters Theses & Specialist Projects
Agriculture contamination is very common in karst systems due to the vulnerability of these aquifers. Animal waste is often spread across crop land to enrich the soil with nitrates and phosphates. Herbicides and pesticides are also applied to the crops. The transport of these pollutants through the soil and epikarst is a difficult process to monitor due to the complex, heterogeneous behavior of the groundwater as it makes its way down to the aquifer below.
An experimental site at Crumps Cave lended a unique opportunity to monitor the vadose zone at a waterfall in the cave below. A previous dye …

Near-Surface Atmospheric Response To Simulated Changes In Land-Cover Vegetation Fraction, And Soil Moisture Over Western Kentucky, Ronnie Leeper
Near-Surface Atmospheric Response To Simulated Changes In Land-Cover Vegetation Fraction, And Soil Moisture Over Western Kentucky, Ronnie Leeper
Masters Theses & Specialist Projects
A series of land-use-land-cover-change (LULCC) based sensitivity experiments, including changes in vegetation type, fractional vegetation (FV), and soil moisture (SM), over Western Kentucky were conducted to investigate atmospheric response to land-use. The choice of land-use for this study was chosen in the context of Western Kentucky’s historical LULCC. For this study, vegetation types considered were grassland, forest, and bare soil with further variations in FV for grassland and forest at 25, 50, 75, and 100 % and systematic increases and decreases in volumetric SM of 0.05, 0.10, and 0.15 m3 m-3. To the author’s knowledge, this is the first assessment …
Modeling Stormwater Pollutant Transport In A Karst Region--Bowling Green, Kentucky, Allison H. Ross
Modeling Stormwater Pollutant Transport In A Karst Region--Bowling Green, Kentucky, Allison H. Ross
Masters Theses & Specialist Projects
The management of stormwater runoff is a particular challenge for communities in karst regions. Most guidelines for compliance with regulations for stormwater monitoring and mapping pertain to non-karst environments. It can be argued that effective stormwater management is even more essential to karst regions because stormwater receives little or no natural filtration as it is transferred through conduits in the subsurface and the buildup of pollutants underneath can be detrimental to community and environmental health if not effectively mitigated. Because of the limited resources available to determine how stormwater runoff carries potential pollutants across the surface before being transferred to …
Vadose Zone Hydrology Near The Vicinity Of Edna's Dome, Mammoth Cave, Kentucky, Johnny Merideth
Vadose Zone Hydrology Near The Vicinity Of Edna's Dome, Mammoth Cave, Kentucky, Johnny Merideth
Masters Theses & Specialist Projects
This study examines the differences in key physical aqueous parameters at two different cave sites separated by only a few tens of meters. One site (FF) has a freefalling water component where water descends nearly 30 meters from the ceiling of a vertical shaft. The other location (WW) appears to have continuous water to rock contact as it descends to near the same level in the cave.
Water samples were collected at the two sites in two week intervals from May to August 2002. While both sites were proximal, they demonstrated very different behaviors, particularly during storm events. Differences in …
