Karst is a term applied to areas where extensive dissolution of rock has led to the development of subterranean channels through which groundwater flows in conduits (enclosed or semi-enclosed channels). These conduits can vary in size from slightly enlarged cracks to tunnels many meters in diameter and many kilometers in length.
The aim of the Knowledge Exchange project is to bring together information on where there is evidence of karst and rapid groundwater flow within the Chalk and the Jurassic and Permian Limestones. This will enable a better understanding of how and where karst is affecting these aquifers. New resources on karst will be developed to enable karst data to be used more easily for groundwater.
