Mediterranean Karst Aquifer Map (WHYMAP MEDKAM). BGR, KIT, UNESCO

The World-wide Hydrogeological Mapping and Assessment Programme (WHYMAP) provides data and information about the earth´s major groundwater resources. Karst aquifers constitute important freshwater resources, but are challenging to manage and to protect, because of their unique structure and hydraulic behaviour, representing continuous challenges for research and development. Karstified carbonate rocks are widespread in the Mediterranean region, where groundwater from karst contributes to the freshwater supply of most countries and many big cities, such as Rome, Montpellier, and Beirut.

Groundwater resources in karst aquifers are often hydraulically connected over large areas and particularly vulnerable to contamination. Rapid and turbulent groundwater flow in a network of conduits and caves often results in variable spring discharge and water quality. The Mediterranean Karst Aquifer Mapping and Database (MEDKAM) project is creating a unique map of karst aquifers in the Mediterranean at a scale of 1:1.5 million and providing additional data on karst springs, caves, and on karst groundwater dependent ecosystems.
