Abstract

Abstract Exceptional hydrometeorological events are common around the Mediterranean. It seems that in this matter Catalan rivers hold the record in terms of intensity, with spectacular impacts in the landscape. The study of some recent events in the eastern French Pyrenees nevertheless shows that if such events potentially pose a dramatic risk, their morphogenic impacts remain limited. During the flood of November 1999 in the Corbières, the channels and floodplains were subjected to significant transformations but the slope systems remained surprisingly unaffected. In the light the effectively heterogeneous spatial distribution of flood-related damage, the existing predictive flood models that have been established for the region do not appear particularly accurate and may need recalibrating.
