On the evening of october 3, 2015, the southern coast of the Alpes Maritimes region was hit by a particularly intense and rapid flash flood episode. The municipalities of Biot, Antibes, Cannes, Mandelieu (non-exhaustive list) were extensively flooded and suffered significant damage. The death toll form these floods reached 20, with substantial material and economic losses (approximately 600 million euros in insured damages according to FFSA). The three main rivers that caused these floods were the Brague (70 km²), the Grande Fraère (22 km²) and the Riou de l'Argentière (48 km²). Among these rivers, only the Brague had a hydrometric station, which was damaged during the flood and did not provide a complete record. This flood event was studied using hydrological approaches or 2D hydraulic modeling tools. Here, we propose to model and simulate this event in the downstream area of the Brague river, using a 1D-2D approach enabled by the HEC-RAS modeling software.
