Managing the dams of Haute-Vilaine

A real-time decision support and forecasting system for effective management of dams between stakeholders

The three dams built in the Haute-Vilaine region in the 1970s serve two purposes: to protect the area against the flooding of the Vilaine section upstream of the city of Rennes, and to create a drinking water reservoir for the eastern sector of the region. These three dams — the Haute-Vilaine barrage, the Cantache barrage and the Valière barrage — are managed by the Department of Ille-et-Vilaine department and Veolia, and have a total maximum capacity of about 20 million m3. Using MIKE OPERATIONS, we have provided a decision support system that allows effective daily management between the different stakeholders of these dams.
