OHMCV: Cevennes‐Vivarais Mediterranean Hydrometeorological Observatory

The Cévennes-Vivarais Mediterranean Hydro-Meteorological Observatory (OHMCV) is an observation service dedicated to thunderstorms generating intense rains and flash floods in the medium mountainous Mediterranean region. For this purpose, OHMCV develops three observation strategies: (1) detailed, long‐lasting, and modern hydrometeorological observation over part of the region of interest, the Cévennes‐Vivarais region, for the purpose of process studies and the improvement and assessment of coupled hydrometeorological predictive models; (2) multidisciplinary postflood investigations following the most extreme events wherever they occur in the Mediterranean region to document and analyze the physical processes and societal factors involved; and (3) use of historical information available on past floods to better characterize the frequency of extreme hydrometeorological events and possible trends in a changing climate. OHMCV participates to the international HyMeX program. It is a member of the Network of Drainage Basins (RBV) and OZCAR Infrastructure.
