Safran-Isba-Modcou (SIM) : Un outil pour le suivi hydrométéorologique opérationnel et les études

Abstract

The SAFRAN-ISBA-MODCOU model combines an analysis system of the atmospheric forcing, a land surface scheme, and a hydrogeological model. Extensive research work has been done around this suite during the last fifteen years. Since 2003, it has been transferred to Météo-France real-time operational environment and has been progressively supplied with an extended climatology. Its operational use now covers water resources monitoring, flood forecasting, and drought assessment. It is also particularly useful to study the impact of climate change on the water cycle.
