Karst hydrology emerged as a discipline in the late 1950s and the early 1960s in France. Previously, the activities of cave explorers, called speleologists, had been dismissed as more of a sport than a science and so the underground karst caves and their associated watercourses were, from a scientific perspective, understudied.

A polje, also called karst polje or karst field, [1] [2] [3] is a large flat plain found in karstic geological regions of the world, with areas usually in the range of 5–400 km 2 (2–154 sq mi). The name derives from the Slavic languages , [ 4 ] [ 5 ] where polje literally means 'field', whereas in English polje specifically refers to a ...
Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum. [1] It has also been documented for weathering -resistant rocks, such as quartzite , given the right conditions. [ 2 ]
Speleogenesis is the origin and development of caves, the primary process that determines essential features of the hydrogeology of karst and guides its evolution. It often deals with the development of caves through limestone, caused by the presence of water with carbon dioxide dissolved within it, producing carbonic acid which permits the dissociation of the calcium carbonate in the limestone.
The formation of permafrost thaw lakes due to warming climate is a positive feedback loop, as methane, nitrous oxide and carbon dioxide are released as permafrost thaws, contributing to further climate warming. [1] [2] The Batagaika crater in Siberia is an example of a large thermokarst depression.
A solutional cave, solution cave, or karst cave is a cave usually formed in a soluble rock like limestone (Calcium carbonate CaCO 3). It is the most frequently occurring type of cave. It is the most frequently occurring type of cave.
Speleology (from Ancient Greek σπήλαιον (spḗlaion) 'cave' and -λογία 'study of') is the scientific study of caves and other karst features, as well as their composition, structure, physical properties, history, ecology, and the processes by which they form (speleogenesis) and change over time (speleomorphology).
The Dobra River enters a 17 km long cave system at Đulin ponor [] in Ogulin, Croatia.. A ponor is a natural opening where surface water enters into underground passages; they may be found in karst landscapes where the geology and the geomorphology is typically dominated by porous limestone rock.
