RÉSUMÉ

This work deals with the numerical modeling of dam-break flow over an erodible bed. The mathematical model is a combination of the shallow water, the transport diffusion, and the bed morphology change equations. The system is solved by the finite volume Roe scheme, associated with an original treatment of the source term. The results of several tests are presented in order to verify and validate the performance of the model.
