Abstract

The works devoted to the hydrological use of radar during the last few years in France have brought to light both the potential concern and the limitation of this measurement technique as regards the quantitative evaluation and the forecast of rainfall. These initial results are based on many experiments specifically devoted to hydrology. Following synthesis about recent researches in France and abroad, the results obtained from the Radar-Cévennes are set forth. Finally, the aim of this experiment is to assess the contribution of the double polarisation measurement technique and the need to integrate a radar in a flood announcement system.
