PhD position at ENIT (Tarbes) and IMFT (Toulouse): Impact model for the evaluation of the flooding risk.

Context and objectives:

The term “flash flood” refers to sudden floods having high peak discharges in a short response time. They result from a combination of meteorological and hydrological factors. Intense storm events delivering high amounts of rain water appear to be the first condition for flash flooding to be initiated. Watershed characteristics such as small catchments (under 500 km2 ) or steep slopes are associated with short and rapid flood timing. Flash floods are one of the most destructive hazards in the Mediterranean region and have caused casualties and billions of euros of damages in France over the last two decades. The recent case of June 2013 occurred in the Pyrenees killed 2 people and resulted in thousands of victims. The damages were estimated at about 134 million euros. The contrasted topography, the complexity of the continental surfaces in terms of geology and land use, the difficulty to characterize the initial moisture state of the catchments make these extreme events very difficult to assess and predict. The proposed PhD will aim at improving the understanding of the hydrological response by contemporary use of empirical and analytical (or rainfall-runoff) modelling. The ambition is to develop an operational methodology for the anticipation of the risk of inundation. The work will include an inter-comparison of models dedicated to flash flood prediction and allowing the characterization of the resulting risk. The proposed work will therefore contribute to the building of a relevant methodology of risk evaluation for a better protection of the population. The long-standing collaboration between the IMFT and the SCHAPI2 will facilitate the transfer of knowledge to the appropriate operational services. Leer más de esta entrada
