What do you mean by karst topography?
Moreover, what are the characteristics of a karst topography?
Karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone.
Simply so, where does karst topography occur?
Karst and potential karst areas in soluble rocks in the contiguous United States. These are areas where carbonate rocks are known to occur in the relatively shallow subsurface and where voids are known to propagate up through the cover of overlying sediment.
Common geological characteristics of karst regions that influence human use of its land and water resources include ground subsidence, sinkhole collapse, groundwater contamination, and unpredictable water supply.
