Influence Of Spring Flow Reversals On Cave Dissolution In A Telogenetic Karst Aquifer, Mammoth Cave, Ky, Chelsey Kipper Oct 2019

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 …

An Urban Karst Aquifer Resource Evaluation And Monitoring Toolbox, Rachel Anne Kaiser

Masters Theses & Specialist Projects

In urban karst areas, such as the City of Bowling Green, Kentucky and the Tampa Bay Metropolitan Area, groundwater quality faces a variety of threats. The development of residential, commercial, and industrial landuse types allows for a wide variety of groundwater pollutants to enter the karst groundwater systems. Various different models and indices have attempted evaluative approaches to identify issues in urban karst areas, but the methods vary by location and lack a focus on urban karst groundwater quality. There also exists a lack of a data-driven approach that is able to capture short- and long-term changes in threats to …


Analysis Of Permaculture’S Water Conservation And Crop Supporting Abilities, Hannah Chaney May 2019

Analysis Of Permaculture’S Water Conservation And Crop Supporting Abilities, Hannah Chaney

Mahurin Honors College Capstone Experience/Thesis Projects

In the Middle East, virtually all agriculturally viable land is under high threat of desertification due to poor land and resource management and climate change. Mulching using straw flakes (straw mulch permaculture) is a method commonly used in successful dry land permaculture projects in the Middle East. We proposed that straw mulch permaculture would increase the amount of soil moisture during dry periods and that this method would not impact the growth and survival of the crop. In order to test this hypothesis, we took soil samples from plots with and without straw mulch permaculture in Bowling Green, KY and …
