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 …

Geology Of Mammoth Cave National Park, Kentucky, Matthew M. Crawford, Rickard A. Olson, Rickard S. Toomey Iii, Lillian J. Scoggins

Map and Chart--KGS

Mammoth Cave National Park in south-central Kentucky was authorized as a national park in 1926 and was fully established in 1941 to protect the cave system, scenic landscape, and diverse flora and fauna. The park contains 52,830 acres and most of the longest recorded cave system in the world, with more than 390 miles of mapped passages as of 2013. Even though Mammoth Cave is famous, people are often unaware of the park's intricate connection to the outside region. This poster shows the geology of Mammoth Cave and the interconnected issues that are important to the park and its visitors. …

Groundwater Quality In Watersheds Of The Big Sandy River, Little Sandy River, And Tygarts Creek (Kentucky Basin Management Unit 5), R. Stephen Fisher, Bart Davidson, Peter T. Goodmann

Report of Investigations--KGS

The Kentucky Geological Survey and the Kentucky Division of Water are evaluating groundwater quality throughout the commonwealth to determine regional conditions, assess impacts of nonpoint-source contaminants, provide a baseline for tracking changes, and provide essential information for environmental-protection and resource-management decisions. These evaluations include summarizing existing regional groundwater-quality data and reporting the results of expanded, focused groundwater collection programs in specific areas. This report summarizes groundwater sampling and analysis in Kentucky basin management unit 5 (watersheds of the Big Sandy River, Little Sandy River, and Tygarts Creek in eastern Kentucky).

Thirty wells and springs were sampled quarterly between the fall …

A 700-Year History Of Groundwater Recharge In The Drylands Of Nw China, John B. Gates, W. Mike Edmunds, Jinzhu Ma, Paul R. Sheppard

Department of Earth and Atmospheric Sciences: Faculty Publications

A 700-year semi-quantitative history of diffuse groundwater recharge in the Badain Jaran Desert (Inner Mongolia) is proposed on the basis of solute data from multiple unsaturated zone groundwater profiles using mass balance of chloride to establish recharge rates and profile chronologies. Four relatively humid (1330–1430, 1500–1620, 1700–1780 and 1950– 1990) and three relatively arid phases (1430–1500, 1620–1700 and 1900–1950) are discernable across the profiles. The recharge history broadly reflects multidecadal to centurial timescale precipitation changes in the northern Tibetan Plateau and suggests that variations in East Asian Summer Monsoon intensity affect desert recharge rates. Uncertainties in the records owing to …
