In recent decades, the watershed of the Rhône River, upstream of Lake Geneva in Switzerland, has suffered three major floods that have caused damages for over 500 million dollars. This led to the third correction of the Rhône River, which aims to improve flood protection in the basin. In this context, the MINERVE system for forecasting and flood management aims to improve the hydrometeorological information in the basin taking into account the existing network of reservoirs and hydropower plants. The first phase of the project began in 2002 with various applied research projects aiming to develop a hydrological and hydraulic model capable of quickly and easily modeling complex basins. Then, these investigations were put into operational phase in 2011 to provide a real-time operating system for flood forecasting and management in the Rhone River.
