Write a short note on Karst topography.
Karst topography is the irregular landscape of sinkholes, caves, disappearing streams and springs formed by groundwater dissolving soluble rock, mainly limestone and dolomite. It is named after the Karst region of Slovenia. It needs soluble rock, a system of joints, and enough rainfall. In Nepal it is found in limestone areas, e.g. around Pokhara (Mahendra Cave). It is a problem for dams and tunnels because of leakage and collapse.
