La Brague basin

 

France

OVERVIEW OF DEMO AIM

The mountains located near the French Mediterranean coast are regularly subject to severe rainfalls, and consequently to torrential floods. On 3rd, Oct. 2015, a dramatic flood occurred in the region between Cannes and Nice (twenty peoples died, 550-650M€ of losses). Three rivers experience particularly dramatic floods in 2015:

  • The Riou de l’Argentière (47 km², mountainous basin),
  • The Frayères (22 km², rural headwaters, urban lowlands),
  • The Brague (68 km², rural and forested basin, urban lowlands).

The latter has been chosen as DEMO site for its bigger size, greater diversity and more numerous data.

  2. Both population and economy benefit from them.
  3. Natural Assurance Scheme are to be defined.
