Sens technique

Action on a river for recovering the entire bed and river banks of the watercourse to achieve the priority goal of increasing the hydraulic capacity of the targeted segment. This implies flow acceleration and therefore an increased flood risk downstream. It is a major process that deeply changes the cross-section and most often the longitudinal profile of the river, resulting in an entirely modified environment: removal of vegetation on the river banks, destruction of fish habitats, etc.
