Flooding in the Bourbre basin (Isère)

Abstract

Flood risk management is one of the aspects of the problem of water course management and can affect water resources and the associated ecosystem. The factors at the origin of the risk call for an exhaustive study at basin level. Applied to the Bourbre basin (Isère), the « Inondabilité » method provides an objective knowledge base which allows an appropriate management scheme to be set out. The operational consequences of this study are described as well as the progress that still has to be made to generalise this type of approach. This particular case indicates the importance of having an objective knowledge of the risk to implement the golden rule of Dynamic Braking in water management and to achieve reasonable land use control in flood plains.
