Introduction. Karst topography is a type of landscape where areas rich in carbonate rocks are sculpted by water (Tarbuck and Lutgens, 2002). Associated with karst topography is the development of sinkholes, which are depressions created by the removal of soluable rock by groundwater (Tarbuck and Lutgens, 2002).
