Subsidence from sinkhole collapse is a common occurrence in areas underlain by water-soluble rocks such as carbonate and evaporite rocks, typical of karst terrain. Almost all 50 States within the United States (excluding Delaware and Rhode Island) have karst areas, with sinkhole damage highest in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania. A conservative estimate of losses to all types of ground subsidence was $125 million per year in 1997. This estimate may now be… Expand

Hydro-mechanical modeling of sinkhole occurrence processes in covered karst terrains during a flood
Abstract Groundwater is an aggravating factor in karstic sinkhole activity as it exacerbates infiltration, percolation, soil saturation and drainage. The exceptionally high number of ground collapsesExpand
Assessing the effects of rainfall, groundwater downward leakage, and groundwater head differences on the development of cover-collapse and cover-suffosion sinkholes in central Florida (USA).
Results indicate that heavy rainfall/storm(s) and rapid increase of head differences within a relatively short period of time are major factors affecting the timing of sinkhole occurrences, and the spatial variation of groundwater downward leakage rate can be used to generate sinkhole susceptibility zonation maps for serving as a useful indicator of the likelihood of sink hole development at certain areas.
