Kentucky Is Karst Country! What You Should Know About Sinkholes And Springs, James C. Currens

Information Circular--KGS

Kentucky is one of the most famous karst areas in the world. What is karst? It's a landscape with sinkholes, sinking streams, caves, and springs. Much of Kentucky's beautiful scenery, particularly in the Inner Bluegrass Region, is the result of the development of karst landscape. A large amount of Kentucky's prime farmland (including its famous horse farms) is underlain by karst, and springs and wells in karst areas supply water to thousands of homes. Many of Kentucky's major cities, including Frankfort, Louisville, Lexington, Lawrenceburg, Georgetown, Winchester, Paris, Versailles, Nicholasville, Fort Knox, Bowling Green, Elizabethtown, Munfordville, Russellville, Hopkinsville, …

Mapped Karst Groundwater Basins In The Lexington 30 X 60 Minute Quadrangle, James C. Currens, Randall L. Paylor, Joseph A. Ray

Map and Chart--KGS

This map shows karst groundwater basins in the Lexington quadrangle, determined primarily by groundwater tracer studies. It can be used to quickly identify the groundwater 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 groundwater in the area.

Inventory Of Karst Springs Of Fayette County, Kentucky, James C. Currens, Qianhong Wu, Kenneth G. Pidgeon

Map and Chart--KGS

The purpose of this publication is to document karst springs in Fayette County and provide a resource to help the county's citizens avoid the geologic hazards associated with building near springs during future urban development. It may be used as an aid in locating potential groundwater discharge points in case of hazardous material spills, and to provide a foundation for future studies of the hydrogeology and karst geology of the Inner Bluegrass Region.

It is also a basic historical record of the springs of Fayette County. Although over 350 springs are reported here, this inventory is not exhaustive. At the …

Subsidence Hazards As A Consequence Of Dam, Reservoir And Tunnel Construction, Petar Milanovic

International Journal of Speleology

Considering all man-made structures in karst areas, dams, reservoirs and tunnels are the most vulnerable in relation to induced subsidence and caverns. Reservoirs that are located entirely or partially on karstified rocks covered with unconsolidated sediments are especially subsidence-prone. As a consequence of induced subsidence a number of reservoirs in karst areas failed and were never fully filled. Such subsidence formation is very damaging because the development is unpredictable and practically instantaneous. Reservoirs in karst areas may fail to fill despite an extensive site investigation programs and sealing treatment. Every problem is unique and past experiences are never repeated. This …

Karst Subsidence In South-Central Apulia, Southern Italy, Marco Delle Rose, Mario Parise

International Journal of Speleology

Subsidence in the karst of Apulia (Southern Italy), one of the classical karst areas of Italy, is described in this paper. The carbonate rocks that make up the geological structure of the Apulia region are affected by subsidence, which is of different type and intensity depending upon geological, topographical, and hydrogeological conditions. In particular, we discriminate between inland subsidence and coastal subsidence. Inland subsidence is generally restricted to the presence of individual cavities, either empty or partly or totally filled with deposits produced by dissolution of soluble rocks underground. Locally, such subsidence can cause severe effects on anthropogenic structures above. …
