Karst represents a specific area consisting of surface relief and surface-underground hydrographic networks resulting from the water circulation and its aggressive chemical and physical action in joints, farsctures and cracks along the layers of soluble rocks, such as limestone, chalk, dolomite, as well as gypsum and salt.

Perspective on karst hydrology
Journal of Hydrology, 1983Abstract Karst hydrology has many aspects, all worthy of intensive and separate study. Variable sensitivities of carbonate rocks to natural processes on and in the hydrologic system have led to great ranges in conditions, many of which relate directly or indirectly to permeability.

Hydrology of the Greenbrier Karst
2017Studies of the karst drainage systems of the Greenbrier limestone in southeastern West Virginia began in the early 1960s and were the first to make extensive use of water-tracing techniques and cave mapping in the USA. The carbonate aquifer is about 400 ft (120 m) thick in the Swago Creek area west of Marlinton (Pocahontas County) increasing to 1000 ft

Cadmium behavior in a karst environment hydrological cycle
Environmental Science and Pollution Research, 2020Karst regions are important water providers, supplying approximately 25% of the world population. These areas present higher vulnerability to contamination due to hydrodynamics, which hampers the natural depuration of these waters until reaching the underground environment.

Karst Hydrology and Chemical Contamination
Journal of Environmental Systems, 1992Ground-water flow in karst aquifers is very different from flow in granular or fractured aquifers. Karst ground-water flow is often turbulent within discrete conduits that are convergent in their upper reaches and may be divergent in their very lower reaches, simulating the flow pattern of surface water streams that are dendritic or trellised but with ...

Endokarst is underground karst. It is not a primary phenomenon because sedimentation takes place without forming syngenetic cavities. Simultaneously, however, the disposition for bedding interstices (banking) is created. Reef limestones are an exception to this rule because primary cavities are formed in them during the growth of the biological reef ...

Hydrologic classification of caves and karst
2020Karst landscapes form where solutional removal of bedrock is the dominant process in landform development. Subsurface solution conduits are best studied as cave systems, forms produced during part of the karst hydrologic cycle. The general public poorly understands karst landforms and processes, as evidenced by its opinion of cave conduits and its use ...

Underground cavities with karst-hydrological activity percade the karstified region in a three-dimensional network. The movements of the water, especially the slow ones, are hindered only slightly so that there is a division in space, the accumulations of water below, the water-impoverishes areas above.

Hydrologic Response of a Karst Watershed
Transactions of the ASAE, 1994A ground water catchment was instrumented as a karst hydrology and water quality laboratory to develop long-term flow and water quality data. This catchment located in Woodford and Jessamine Counties in the Inner Bluegrass, Central Kentucky encompasses approximately 1620 ha, 40 water wells, over 400 sinkholes, 2 karst windows, and 1 sinking stream.
