Flood Risk Management of the Avançon river – physical model based study

The sediment transport capacity of the Avançon river through the city of Bex in Switzerland is limited. During the October 2000 flood event, water levels rose to danger limits. After the flood, the river channel was completely filled with sediments, with a uniform layer thickness comprised between 1.7 and 1.8m through the village. The return period of the flood event was estimated to be around 20 years, but the amount of transported sediments was extremely high for such an event.
