Hydrochemistry In An Alpine Karst System, Sequoia And Kings Canyon National Parks, California, Joel Despain
Masters Theses & Specialist Projects
This study uses high-resolution, long-term conductivity, temperature, discharge, pH, and laboratory data from 2001 through 2003 from an alpine karst spring located at 2,500 m amsl in Sequoia National Park, California to reveal detailed chemical parameters of this karst system. The data show a system with a pronounced spring run-off, extended periods of base flow quiescence, storm responses tied to precipitation as rain or as snowfall, and clear diurnal and seasonal patterns of discharge. pH and spC values show an inverse relationship to discharge and temperature, which are generally in phase. Total inorganic carbon (TIC) and the fraction of mineral-derived …
Hydrolgeologic Groundwater Sensitivity And Vulnerability Mapping In South Central Kentucky, Andrea Croskrey
Hydrolgeologic Groundwater Sensitivity And Vulnerability Mapping In South Central Kentucky, Andrea Croskrey
Masters Theses & Specialist Projects
Groundwater sensitivity (Ray and O'dell 1993 a) refers to the inherent ease with which groundwater can be contaminated based on hydrogeologic characteristics. We have developed digital methods for identifying areas of varying groundwater sensitivity for a ten county area of south-central Kentucky relevant to a scale of 1: 24,000. The study area includes extensive limestone karst sinkhole plains, with groundwater that is generally extremely sensitive to contamination. Digitally Vectorized Geologic Quadrangles (DVGQs) were combined with elevation data to both identify hydrogeologic groundwater sensitivity regions and to identify zones of "high risk runoff where contaminants could be transported in runoff from …
