Cartographie des chutes de neiges extrêmes dans les Alpes Françaises en utilisant les processus Max-Stables
Résumé
Avalanche release depth: input parameter of avalanche propagation models (Naaim & al. 2003; Lachamp & al., 2002) ; traditional engennering assumption: correspond to fresh snow depth (1 or 3 days). Objective: long term management: obtain fresh snow depths maps for different return periods and accumulation periods ; improve the setting up of territorial planification tools such as hazard maps or risk prevention plans (PPR) ; improve the conception of protection tools in terms of functional characteristics (height, orientation...).
