Abstract

Flood propagation and sediment transport differ by their characteristic time scale. As a consequence, flood damages are more familiar than morphological evolution, which remains more often a domain for the specialist. The objective of this paper is to show, through some examples, how much these two domains are interrelated, and to convince that flood hazard protection must take into account sediment transport and morphological consequences.
