Speleothem climate capture of the Neanderthal demise
… monitoring programme has classified the karst hydrology, cave ventilation, processes influencing speleothem growth and proxies preserved within speleothem calcite. Three speleothems were used to develop records of past climate and environmental variability between 90,000 and 30,000 years …

Fate and Transport of E. coli Through Appalachian Karst Systems
Karst waters serve as important water sources in rural Appalachia and are well-connected to surface waters, making them susceptible to anthropogenic contamination, including by fecal indicator bacteria which represent a public health risk. This work designed and implemented a watershed-scale …

An Investigation of Groundwater Flow in the Vicinity of Patoka Dam, Indiana
… throughout the United States have been built on karst terrains, where soluble limestone bedrock has been dissolved to form features such as caves, sinkholes, and underground rivers. In such karst regions, subsurface hydrology can play an integral role in the condition, operation, and safety of …

Investigation of the Flow and Fate of Nitrate in Epikarst at the Savoy Experimental Watershed, Northwest Arkansas
<p>Many karst aquifers are at high risk of nitrate contamination due to a combination of vulnerable geology characterized by thin soils and conduit flow, and excess inputs of nutrients from animal feeding operations. One zone that is present in many karst regions and could play an important role in …

Determining the Sustainability of Coal Mine Cavity Discharge as a Drinking Water Source
… to the extremely heterogeneous system seen in karst landscapes. Thus, techniques common to karst phenomenon were used to analyze the spring hydrograph. A spring recession analysis was performed upon five storm recessions, and the coefficients for each recession compared and discussed in light …

Hydrogeophysical quantification of infiltration and recharge through soil-filled sinkholes using Time Domain Reflectometry and Electrical Resistivity Tomography
This dissertation presents the results of a detailed physical and hydrogeophysical study of two soil-filled sinkholes mantled by ancient New River fluvial terrace deposits. Research was performed at the Virginia Tech Kentland Experimental Farms in Whitethorne, Virginia, USA between fall 2003 and …

AN INVESTIGATION OF HYDROGEOLOGIC, STRATIGRAPHIC, AND STRUCTURAL CONTROLS ON ACER GRANDIDENTATUM COMMUNITIES IN A KARST LANDSCAPE, OWL MOUNTAIN PROVINCE, FORT HOOD MILITARY INSTALLATION, TEXAS
… relicts <em>Acer grandidentatum</em>, within karst terrains. These systems exhibit complexly overprinted speleogenetic evolutions within a dynamic groundwater regime resulting from regional climate shifts throughout the Neogene that have been complicated by extensive anthropogenic …
