    Hydrogeological heritage in the Languedoc, and Roussillon- the role of the National Inventory of the French Geological Heritage
    Since the law of February 27th 2002 in France, the geological heritage is an integral part of the great natural heritage inventory established for the entire land territory, fluvial and marine (Article L. 411-5 of the environmental code).**The geologic heritage of the Languedoc and Roussillon is one of the richest in France, by its diversity and its abundance. 253 remarkable geological sites representing 3 580 km C (13 % of the regional territory) were listed+ they restore the history of the Earth over the past 600 million years. This inventory constitutes a scientific, educational, cultural, economic and tourist asset.**More than 20% of these sites have been identified for their hydrogeological relevance and associated phenomena (thermalism, karst process, fluvial erosion…). These are springs, swallow holes, caves, canyons, kart systems, poljes, potholes… essentially located on mesozoïc carbonate rocks. However, some of them such hot springs along the Têt River valley emerge along a polyphased fault in paleozoic granitic units or are in paleozoic cover.**The diversity of hydrogeological heritage in Languedoc and Roussillon reflects the exceptional geological diversity of this territory. The inventory of geological heritage is an essential tool to enhance knowledge, develop educational actions preserve and sustainably manage our regional territory.**
