types of karst
There are a wide variety of surface and subsurface features associated with various karst terrains. They occur at a wide range of scale due to processes both past and present. However, not all features will be found at all locations. In general, the types of karst features can be divided into surface landforms and subsurface features. The surface landforms include sinkholes (dolines), areas of subsidence, sinking streams, springs and cave entrances. The subsurface features are the areas of dissolution within the rock.
