Manager of the Larzac site : Jean Chéry

The Durzon site is located on a karstic aquifer with an area of 100 km2 which supplies the Durzon Spring (average discharge 1.4 m3/s). This spring provides a natural supply of drinking water to the Aveyron portion of Larzac. The site is equipped to monitor the discharge from the spring (Grands Causses Nature Park). The Montpellier Geoscience Laboratory provides rainfall monitoring, measurements of underground flows, tiltmeter measurements of the deformations associated with recharge, and surface and underground gravity measurements of selected sites. Additional hydrological and geochemical monitoring are provided by the Montpellier Hydrosciences laboratory. The main scientific issue concerns the dynamics of the transport and storage of water, mainly in the unsaturated zone.
