This paper presents a national study on the detection of climatic changes in hydrological extremes in France. A high number of changes have been detected but after an extensive criticism of data, half of these changes can be related to non-climatic factors, especially metrological issues. A regional analysis based on a reduced number of stations, whose quality can be insured, doesn’t show a consistent and generalized change in French rivers. Specific behaviours have been explained in mountainous basins, related to the increasing of temperature, and in the North of France with an increasing of both rainfall and flood peaks.
