The Hydrology Of The Carroll Cave-Toronto Springs System: Identifying And Examining Source Mixing Through Dye Tracing, Geochemical Monitoring, Seepage Runs, And Statistical Methods, Benjamin Verlinden Miller

Masters Theses & Specialist Projects

In karst areas relationships between activities occurring on the surface and the overall health of the subsurface environment are often highly interconnected. However, the complex nature of karst flow systems can often make identification of these connections difficult. Carroll Cave, a large stream cave system located in the central Missouri Ozarks, is known for its biological and speleological significance. A dye tracing project to delineate a Carroll Cave recharge area through dye tracing has identified an area of 18.5 km2 which contributes water to the cave. The water from Thunder River within Carroll Cave was positively traced to eight springs …

Ground-Penetrating-Radar Reflection Attenuation Tomography With An Adaptive Mesh, Emily A. Hinz, John H. Bradford

CGISS Publications and Presentations

Ground-penetrating radar (GPR) attenuation-difference analysis can be a useful tool for studying fluid transport in the subsurface. Surface-based reflection attenuation-difference tomography poses a number of challenges that are not faced by crosshole attenuation surveys. We create and analyze a synthetic attenuation-difference GPR data set to determine methods for processing amplitude changes and inverting for conductivity differences from reflection data sets. Instead of using a traditional grid-based inversion, we use a data-driven adaptive-meshing algorithm to alter the model space and to create amore even distribution of resolution. Adaptive meshing provides a method for improving the resolution of the model space while …

Water Management Plan For The Town Of Perenjori, Mark Pridham

All other publications

The Rural Towns – Liquid Assets (RT–LA) project was established with the aim of integrating salinity, waterlogging and flooding control with development of new water supplies in wheatbelt towns, and where possible, finding ways of putting the excess water to commercial use. Following the identification of effective integrated water management strategies, these have been applied to the 15 Shires participating in the DAFWA led RT–LA project. This report summarises the outcomes from all scientific investigations undertaken for Perenjori. In addition it presents the water management options, a preliminary analysis of those options and the priority recommended ones. Due to the …

Assessment Of Groundwater Quality In An Abandoned Feedlot, Henderson County, Kentucky: Data Report, E. Glynn Beck, James S. Dinger, John Grove, Eugenia Pena-Yewtukhiw

Information Circular--KGS

A three-phase project investigated the influence of past and present agricultural practices on groundwater resources in the Western Kentucky Coal Field. Phase II concentrated on past practices, specifically those associated with an abandoned dairy feedlot and an old homestead. Results of phase II analyses are presented in this report.

Sources And Occurrences Of Nonpoint-Source Chemicals In Groundwater, Jackson Purchase Region, Kentucky: Data Report, E. Glynn Beck

Information Circular--KGS

Groundwater from the Jackson Purchase Region was sampled to investigate possible contamination by nonpoint-source chemicals. Conclusions drawn from the resulting data and methodology can be found in “Sources and Occurrences of Nonpoint-Source Chemicals in Groundwater, Jackson Purchase Region, Kentucky,” Kentucky Geological Survey Report of Investigations 22 (series 12), by R.S. Fisher and E.G. Beck.

Assessment Of Groundwater Quality In A Remediated Abandoned Feedlot, Henderson County, Kentucky: Data Report, E. Glynn Beck, James S. Dinger, John Grove, Eugenia Pena-Yewtukhiw

Information Circular--KGS

A three-phase project investigated the influence of past and present agricultural practices on groundwater resources in the Western Kentucky Coal Field. Phase III concentrated on an abandoned dairy feedlot that had been remediated. Results of phase III analyses are presented in this report.

Sources And Occurrences Of Nonpoint-Source Chemicals In Groundwater, Jackson Purchase Region, Kentucky, R. Stephen Fisher, E. Glynn Beck

Report of Investigations--KGS

Nitrate concentrations that exceed U.S. Environmental Protection Agency drinking-water standards have been reported in Jackson Purchase Region groundwater since the 1960's. More recently, other nonpoint-source chemicals such as pesticides and volatile organic compounds have also been found. The sources of these chemicals and the pathways by which they reach domestic groundwater supplies must be determined to protect human health and to design effective land-management practices.

To investigate the occurrence of nonpoint-source chemicals in Jackson Purchase groundwater, 60 wells were selected on the basis of geographic location, hydrostratigraphic unit penetrated, and well type (bored or drilled); distances to row crops, known …
