Impacts Of Carbonate Mineral Weathering On Hydrochemistry Of The Upper Green River Basin, Kentucky, Laura Leigh Osterhoudt
Impacts Of Carbonate Mineral Weathering On Hydrochemistry Of The Upper Green River Basin, Kentucky, Laura Leigh Osterhoudt
Masters Theses & Specialist Projects
Kentucky’s Upper Green River Basin has received significant attention due to the area’s high biodiversity and spectacular karst development. While carbonate bedrock is present throughout the watershed, it is more extensive and homogenous along the river between Greensburg and Munfordville than upstream from Greensburg where the geology is more heterogeneous. This research quantitatively evaluated how lithological differences between the two catchment areas impact hydrochemistry and inorganic carbon cycling. This first required correcting catchment boundaries on previous US Geological Survey Hydrologic Unit Maps to account for areas where the boundaries cross sinkhole plains. Basin boundaries using existing Kentucky Division of Water …
Karstification Of The Pennyroyal Plain Behind The Retreating Chester Escarpment: Warren, Simpson & Logan Counties, Kentucky, Anthony Able
Karstification Of The Pennyroyal Plain Behind The Retreating Chester Escarpment: Warren, Simpson & Logan Counties, Kentucky, Anthony Able
Masters Theses & Specialist Projects
Hydrogeologic investigations were conducted on the drainage systems of an area of the Pennyroyal sinkhole plain of south central Kentucky. The degree of karstification of five area streams was studied to develop an understanding of the evolution of drainage as the landscape changes from a sandstone caprock plateau to a limestone sinkhole plain. The Chester Upland, capped by the Big Clifty Sandstone, possesses predominantly surface drainage and the Pennyroyal Plain, formed on Mississippian limestones, possesses considerable subsurface drainage. As the Chester Upland Escarpment retreats and surface streams are onto the limestones, the streams evolve to become subsurface streams. The five …
