The DIKTAS area
The term “karst” is applied to a specific geological landscape and morphology that develops wherever limestone formations, or other carbonatic rocks, constitute the bulk of the geological substratum of a region and outcrop over extensive areas. Due to their solubility, these rock formations develop high permeability along fractures and faults, with the formation of sinkholes, chasms, underground streams, and caves. “Karst” hydrogeology is hence characterized by very high fracture controlled heterogeneous permeability, almost total absence of surface drainage (which has been largely diverted into subterranean routes), high infiltration rates and rapid underground flows of groundwater.
In the framework of the DIKTAS project, eight transboundary aquifers have been chosen for more detailed investigation.
