Generalized Block Diagram Of The Eastern Pennyroyal Karst, James C. Currens Jan 2001

Generalized Block Diagram Of The Eastern Pennyroyal Karst, James C. Currens

Map and Chart--KGS

Karst occurs where limestone or other soluble bedrock is near the earth's surface, and fractures in the rock become enlarged when the rock dissolves. Sinkholes and sinking streams are two surface features that indicate karst development. In karst areas most rainfall sinks underground, resulting in fewer streams flowing on the surface than in non-caves, sometimes reemerging at karst windows, then sinks again to eventually discharge at a base-level spring along a major stream or at the top of an impermeable strata. The development of karst features is influenced by the type of soluble rock and how it has been broken …

Karst Occurrence In Kentucky, Randall L. Paylor, James C. Currens Jan 2001

Karst Occurrence In Kentucky, Randall L. Paylor, James C. Currens

Map and Chart--KGS

This map was compiled from a digital version of the 1:500,000-scale geologic map of Kentucky (Noger, M.C., comp., 1988, Geologic map of Kentucky: U.S. Geological Survey). The areas of potential karst development were delineated using stratigraphic units mapped on the geological map. The classification of the potential for karst development was based on the field experience of the authors and other data. A number of isolate carbonated unites that would not have otherwise been differentiated on the geologic map were newly digitized for this map.

Generalized Block Diagram Of The Pine Mountain Karst, James C. Currens Jan 2001

Generalized Block Diagram Of The Pine Mountain Karst, James C. Currens

Map and Chart--KGS

Karst occurs where limestone or other soluble bedrock is near the earth's surface, and fractures in the rock become enlarged when the rock dissolves. Sinkholes and sinking streams are two surface features that indicate karst development. In karst areas most rainfall sinks underground, resulting in fewer streams flowing on the surface than in non-karst settings. Instead of flowing on the surface, the water flows underground through caves to eventually discharge at a base-level spring along a major stream or at the top of an impermeable strata. The development of karst features is influenced by the type of soluble rock and …

Exploring A Small Thrust Fault And Related Features On U.S. Highway 62/68, Near Maysville, Mason County, Kentucky, Paul Edwin Potter, John Grover, Gregory A. Schumacher Jan 2001

Exploring A Small Thrust Fault And Related Features On U.S. Highway 62/68, Near Maysville, Mason County, Kentucky, Paul Edwin Potter, John Grover, Gregory A. Schumacher

Map and Chart--KGS

One of the most unusual highway cuts in all of Kentucky is located approximately 395 ft (120 m) south of the high bridge that crosses Lawrence Creek on U.S. Highway 62/68, near Maysville, Mason County (see Figs. 1-2). The Carter coordinate location of the outcrop is 400 FSL x 900 FEL, 24-AA-69, which corresponds to 38°40'3" N latitude, 83°48'10" W longitude. The roadcut is approximately 1,315 ft (400 m) long, and rises in benches to a height of almost 110 ft (33 m). About 30 to 36 ft (9 to 11 m) of the Grant Lake Limestone is exposed at …

Mapped Karst Ground-Water Basins In The Bowling Green 30 X 60 Minute Quadrangle, Joseph A. Ray, James C. Currens Jan 2000

Mapped Karst Ground-Water Basins In The Bowling Green 30 X 60 Minute Quadrangle, Joseph A. Ray, James C. Currens

Map and Chart--KGS

This map shows karst ground-water basins in the Bowling Green quadrangle, determined primarily by ground-water tracer studies. It can be used to quickly identify the ground-water basins and springs to which a site may drain. Major springs and the relative size of their catchment areas can be evaluated for potential as water supplies. The map also serves as a geographic index to literature on karst ground water in the area.

Mass Flux Of Agricultural Nonpoint-Source Pollutants In A Conduit-Flow-Dominated Karst Aquifer, Logan County, Kentucky, James C. Currens Jan 1999

Mass Flux Of Agricultural Nonpoint-Source Pollutants In A Conduit-Flow-Dominated Karst Aquifer, Logan County, Kentucky, James C. Currens

Report of Investigations--KGS

Changes in water quality in a karst ground-water basin used intensively for agriculture are being measured before, during, and after the implementation of best management practices (BMP’s) and other management practices, to determine the success of such programs in protecting ground water. The study was divided into three phases. The results of the first two phases are included in this report and cover research conducted between August 1990 and October 1994. During phase I of the study the overall ground-water quality of the basin and its hydrogeology were investigated. Phase II began monitoring the water quality at Pleasant Grove Spring …

Impacts Of Agricultural Transformation On The Principal Karstic Regions Of France, Jean Nicod, Jean-Noël Salomon Jan 1999

Impacts Of Agricultural Transformation On The Principal Karstic Regions Of France, Jean Nicod, Jean-Noël Salomon

International Journal of Speleology

The recent extension of intensive agriculture on the karst plateaus has caused different types of impact: soil management, generalised and/or localised pollution. Yet paradoxically rural depopulation can also have negative impacts, which largely depend on the characteristics and the hydrological function of the different karst environments. They are often negative, particularly as far as the water quality is concerned, which is why protection measures are undertaken, either in a defined area for a catchment, or in the framework of regional parks. But this is not always the case, so it is appropriate to analyse the problem of karst pollution as …

Environmental Vulnerability And Agriculture In The Karstic Domain: Landscape Indicators And Cases In The Atlas Highlands, Morocco, Brahim Akdim, Mohammed Amyay Jan 1999

Environmental Vulnerability And Agriculture In The Karstic Domain: Landscape Indicators And Cases In The Atlas Highlands, Morocco, Brahim Akdim, Mohammed Amyay

International Journal of Speleology

After the brief presentation of the major karstic areas in Morocco, the article focused essentially on the Atlas mountains to investigate the impact of the agriculture on the natural systems equilibrium. Socio-economic changes (demographic pressure, escalation of the landscape use, utilisation of new techniques in water harvesting, etc...) have sometimes fathered mechanisms of degradation. Many indicators seem to reflect these mechanisms. The pedologic indicators, soil erosion, the hydrologic and geomorphic indicators, are apprehended to demonstrate existent correlation between different variables and the often negative impacts of land over-use in the karstic domain of the Middle Atlas.

Hydrology And Water Quality In The Central Kentucky Karst: Phase 1, James F. Quinlan, Donald R. Rowe Jan 1977

Hydrology And Water Quality In The Central Kentucky Karst: Phase 1, James F. Quinlan, Donald R. Rowe

KWRRI Research Reports

Study of springs and cave streams has shown that heavy metal-rich effluent from a wastewater treatment plant can be traced to Hidden River Cave (beneath the city of Horse Cave) and thence 4 to 5 miles north to a group of 39 springs at 14 locations along a 5-mile reach of Green River. Nickel, chromium, copper and zinc in these effluent-bearing springs are in concentrations of as much as 30 times greater than other springs upstream and downstream from this reach, 20 times greater than the Green River, and 60 times greater than in shallow domestic wells between Horse Cave …
