Karst depressions are of two major types: dolines and collapse sinks. Dolines tend to be small features, usually ranging in depth between 3 and 10 metres, and are formed above the water table both by solution along zones of weakness in the rock and by the ponding of surface run-off. Collapse sinks are the result of cavern roof collapse and their distribution is dependent on the subterranean drainage system. McConnell and Horn proposed that the distributions of both types of depression would be controlled by a random proces...
