A doline is associated with a Karst valley. A doline is a funnel-shaped depression in a Karst landscape that is formed as a result of the dissolution of limestone or other soluble rocks. When groundwater dissolves the rock, it creates underground caverns that can eventually collapse and form a doline on the surface. Therefore, dolines are typically found in Karst landscapes, which are characterized by the dissolution of soluble rocks and the formation of distinctive surface and subsurface features such as sinkholes, caves, and underground rivers.
