Measurement Of The Effects Of Food Preparation Activities On The Microclimate Of The Snowball Dining Room Area Of Mammoth Cave, Kelly Kaletsky

Masters Theses & Specialist Projects

The stability of Mammoth Cave’s microclimate has never undergone extensive investigation. The Snowball Dining Room area was chosen to measure the microclimate of the cave and to determine if food preparation, human presence and surface temperature variations alter this microclimate. Three portable weather stations containing a temperature / humidity probe, datalogger and microbarograph were placed in various locations along three passageways leading away from the dining room. Readings were taken 24 hours per day for four months. Plotting temperature readings in graph form show a correlation between temperature of the passageway and distance from the dining room.

Radon Contamination Of Residences In A City Built Upon A Karst Landscape Bowling Green, Warren County, Kentucky, James William Webster

Masters Theses & Specialist Projects

The United States Environmental Protection Agency (EPA) estimates that 8 to 12% of U.S. homes have radon concentrations that equal or exceed 4 picocuries per liter (pCi/l). A statewide screening of Kentucky by EPA resulted in an average residential radon concentration of 2.8 pCi/l with 17% of the homes at or above 4 pCi/l. EPA requires routine monitoring and maintenance or worker health records in mines and caves having radon daughter concentrations at or above 0.30 working levels (WL).

A “Drastic” Evaluation Of The Ground-Water Pollution Potential Of Karst Terrain: Lost River Ground-Water Basin, Warren County, Kentucky, David Baize

Masters Theses & Specialist Projects

Karst terrains, such as the Lost River Karst Ground-Water Basin, are extremely vulnerable to ground-water contamination. Seven physical factors: depth to water, recharge, aquifer media, soil media, topography, impact of the vadose zone, and hydraulic conductivity, are evaluated using the DRASTIC system to determine the ground-water pollution potential of the study area. A numerical value is calculated for each of the seven factors, and a map layer for each factor is produced. These layers are then “added” together to produce a DRASTIC ground-water pollution potential map. The effectiveness of each factor in evaluating the pollution potential of karst terrain is …

The Use Of Down-Hole Video To Evaluate Parameters Affecting Removal Of Storm Water Runoff Into A Karst Aquifer In Bowling Green, Kentucky, Philip Reeder

Masters Theses & Specialist Projects

Due to recent land use changes, runoff has greatly increased In Bowling Green, necessitating the drilling of nearly 600 drainage wells to direct storm water into the Lost River Karst Aquifer. Research was conducted to (1) differentiate areas of the city as optimal for removal of storm water runoff, (2) correlate lithologic features between wells, and (3) determine optimal depths to which new drainage wells should be drilled. This was accomplished using maximum capacity tests, correlation of lithologic features between wells and comparing void density to depth below the land surface.

It was only possible to develop general trends in …

Lithologic Controls On Karst Groundwater Flow, Lost River Groundwater Basin, Warren County, Kentucky, Christopher Groves

Masters Theses & Specialist Projects

The Lost River Groundwater Drainage Basin in Warren County, Kentucky, is a karst drainage system encompassing 55 square miles (143 square kilometers) developed within the Mississippian St. Louis and Ste. Genevieve Limestones. Near the contact between these two formations are two bedded chert units, the Lost River Chert Bed (Elrod, 1899) within the Ste. Genevieve and the Corydon Chert Member (Woodson, 1983) of the St. Louis, which appear to be perching layers to shallow karst groundwater flow. Groundwater may be seen flowing on top of these beds in various cave streams and at swallets and springs throughout the basin.

Mechanisms Responsible For Sinkhole Flooding On An Urbanized Karst Terrain: South Sunrise / Media Drive, Bowling Green, Kentucky, Thomas Feeney

Masters Theses & Specialist Projects

Sinkhole flooding on the urban karst area of Bowling Green, Kentucky, was studied by investigating past flood events in the South Sunrise/Media Drive Sinkhole. The actual flood levels of four floods were compared to levels calculated by an empirical runoff determination method. Outflow capacity tests and dye tracing revealed the nature of drainage within the karst depression.

The Soil Conservation Service runoff determination method and the three-hour maximum rainfall event were used to estimate the level of flooding. Three of the four flood events studied provided deviations between the actual and calculated flood levels of less than 0.26 feet (0.08 …

Enteric Contamination Of An Urban Karstified Carbonate Aquifer: The Double Springs Drainage Basin, Bowling Green, Kentucky, Geary Schindel

Acinetobacter calcoaceticus var. anitratum accounted for 2.10% of colonies; Citrobacter freundii for 0.30% Klebsiella pneumoniae for 0.90%; Klebsiella oxytoca, 0.90%; Citrobacter amalonaticus 0.30%; Enterobacter cloacae, 1.20%; …

Impact Of Urban Stormwater Runoff On The Water Quality Of The Subsurface Lost River, Bowling Green, Kentucky, Donald Rice

Masters Theses & Specialist Projects

Bowling Green, Kentucky is located in a distinctive karst region, characterized by subsurface drainage. The Lost River is a large subsurface stream which flows beneath the city. It receives much of the stormwater runoff from Bowling Green, since most of the city's runoff is directed underground. Significant pollutants in Bowling Green's stormwater runoff were identified from water quality test results of storm event grab samples, and a composite sample, of runoff entering the urban By-Pass Cave. Water quality test results were also obtained from storm event grab samples, and a composite sample, of the Lost River at the Blue Hole …

The Lower Reaches Of Long Creek, Kentucky: A Karst Anomaly In Allen County, Doral Conner

Masters Theses & Specialist Projects

A field study of the lower reaches of the Long Creek drainage area in southeastern Allen County, Kentucky, established the karst character of that area. The area heretofore had been described as a non-karst area. Four swallow holes, which individually or collectively totally pirate Long Creek, were identified. Two major resurgences of the pirated flow were located and described. A detailed study of a portion of the Long Creek drainage area revealed thirty-four springs, all of which were pirated at least once, and no flow from these springs reached Long Creek by surficial routes. The field survey also revealed dolines …
