Karst is a type of landscape formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. This process creates unique landforms such as sinkholes, caves, and underground rivers. Karst landscapes are often characterized by distinctive features like disappearing streams, underground drainage systems, and dramatic cliffs. Research in the field of karst typically focuses on understanding the processes responsible for the formation of these features, as well as the hydrology, ecology, and geology of karst environments. Karst research is important for understanding water resources, biodiversity, and geological hazards in these unique landscapes.
