Abstract
Dam impacts have been largely documented in terms of morphological, ecological and economical consequences. However, few study cases analyze dam break impacts. In this publication we discuss biogeomorphological consequences and adjustments due to Malpasset dam break (1959). First, we present the conditions and the causes of the catastrophe. Secondly, we characterized (i) erosion and vegetation encroachment along slope downstream the dam, (ii) poole formation and fill-in and (iii) sediment deposits and reworking. Then, consequences are also characterized in the Frejus plain, near the Mediterranean sea. Biogeomorpholocial processes initiated by Malpsset dam break highlight the potential interest of such site and event to understand major hydromorpohlogical crisis and Mediterrane an streams resiliency.
