Abstract
The aim of the study is to compute the volume of mud which can be eroded in reservoirs by floods. This study has involved site investigations by means of sample drills and the determination of mud erosion laws through flume tests. The modelisation consists in a 1 D. model for flow and the resolution of an advection-diffusion equation for the suspended matter concentration. The flow of erosion and deposition are computed on a 2 D. grid of the bottom.
