OZCAR-RI OHMCV Valescure catchment - France

Hydrometeorological observations within 6 embedded catchments (from 0.3 to 3.9 km2). Mediterranean climate with heavy rainfall and flash floods in automn. The geology is mainly granite. The land use is mainly forest. This site is typical of the Cévennes region. More information at http://www.ohmcv.fr

Operational

Year Established

2003

Purpose

Hydrometeorological extremes in the Mediterranean: intense rain events and subsequent flash-floods How can we improve forecasting of the most extreme rain events among the family of intense events? How can we improve forecasting of the hydrological response in a distributed way at the regional scale as a function of the continental surfaces characteristics (topography, geology, land use…) and initial state (soil moisture)? Geochemistry

History

Mediteranean catchment studied since 2003. 5 gauged stations and 3 rain gauges and 1 meteorological stations
