| Summary: | This article analyses the vulnerability of coastal communities facing coastal flooding hazard, in the region Pays de la Loire (France). This work is related to studies lead after storm Xynthia, 28 February 2010 (Mercier et Acerra, 2011; Przyluski et Hallegattes, 2012; CETE de l’Ouest, 2012a), which submerged many low reliefs(under the altitude of 4,50 m NGF). Xynthia caused considerable damages on habitations and the death of 41 people in Charente-Maritime and Vendée. This article aims to identify, among 120 municipalities in Loire-Atlantique and Vendée, the most vulnerable to coastal flooding hazard. The study intends to understand what make these municipalities potentially vulnerable using a statistical analysis: multiple correspondance analysis (MCA). A typology of municipalities is built according to criteria of vulnerability, such as topography, human and real estate stakes, coastal flooding archives, elements of natural hazards management. Cartographic results show that topographical and historical factors are key elements to determine vulnerable municipalities to coastal flooding hazard. |
