An Adaptive Hazard Planning And Mitigation Framework For Responding To Urban Contamination In Karst Aquifer Systems, James Edward Troxell
An Adaptive Hazard Planning And Mitigation Framework For Responding To Urban Contamination In Karst Aquifer Systems, James Edward Troxell
Masters Theses & Specialist Projects
Environmental hazards in karst regions are damaging and often go unnoticed until an issue has escalated to a point of affecting life or property. The field of emergency and environmental contamination response lacks planning or preparedness focused on remediating groundwater contamination in karst systems. A lack of preplanning before an incident can lead to confusion, delayed response, and the inability to remediate the contaminant. Due to the rapid movement of contaminants through urban karst groundwater aquifers, an efficient response plan that leverages localized data in a GIS should be developed and maintained in order to adequately respond. The objective of …
Hydrogeochemical Characterization And Speleogenesis Of Sistema Huautla In Oaxaca, Mexico, Fernando Hernandez
Hydrogeochemical Characterization And Speleogenesis Of Sistema Huautla In Oaxaca, Mexico, Fernando Hernandez
Masters Theses & Specialist Projects
Sierra Mazateca, Mexico is home to Sistema Huautla, the deepest cave in the Western hemisphere with 1,560 meters of depth and 90 kilometers of passage, including 26 entrances distributed in a high-relief, karstified terrain, within the Sistema Huautla Karst Groundwater Basin. Exploration of the cave has generated research questions about its evolution and geomorphology given the different vadose and phreatic zones impacted by tectonic and incision processes. Dye traces during this study of Cueva de La Peña Colorada confirmed it is a fossil resurgence of the cave system. An additional cave, Cueva Elysium, was connected hydrologically in 2019, expanding the …
Addressing Water Resource Issues In Barbados Through An Isotopic And Atmospheric Characterization Of Precipitation Variability, Veronica Hall
Addressing Water Resource Issues In Barbados Through An Isotopic And Atmospheric Characterization Of Precipitation Variability, Veronica Hall
Masters Theses & Specialist Projects
Numerous studies have analyzed isotopic variation of meteoric and dripwater in karst environments for paleoclimate reconstructions or aquifer recharge capacity. What is poorly understood is how the isotopic signal of δ18O and δ2H is transferred through the hydrologic cycle based upon storm type, frequency, intensity, and teleconnection activity in the tropical karst areas. At Harrison’s Cave, Barbados, a Hobo Onset event data logger was attached to a tipping bucket rain gauge to count the tips and record the total rainfall every 10 minutes. In the cave a Hobo data logger was used to record relative humidity …
Simulation Modeling Of Karst Aquifer Conduit Evolution And Relations To Climate, John D. Broome
Simulation Modeling Of Karst Aquifer Conduit Evolution And Relations To Climate, John D. Broome
Masters Theses & Specialist Projects
ABSTRACT Karst regions of the world that receive relatively similar amounts of precipitation display a wide variety of landscapes. It has been suggested (Groves and Meiman, 2005) that climates exhibiting larger discrete storm events have more dissolving power and consequently higher rates of conduit growth than climates with more uniform precipitation distributions. To study this concept, a computer program “Cave Growth” was developed that modeled the growth of a cross-section of a cave passage under dynamic flow and chemical conditions. A series of 46 simulation datasets were created to represent different climatic conditions. These simulations had the same total annual …
