Méthode D’aide à la Décision Basée Sur un Raisonnement évidentiel Pour évaluer L’efficacité D’un Ouvrage Torrentiel de Stabilisation

This assessment relies on imperfect information (imprecise, incomplete, uncertain), provided by several sources, which relates as far to structures themselves than to natural phenomena scenarios.
