This study analyzes individuals’ perceptions of areas exposed to coastal flooding at a local level using sketch mapping methodology. In this way, 318 individuals were surveyed in four coastal municipalities in France (Barneville-Carteret, Saintes-Maries-de-la-mer, Châtelaillon-Plage and Sainte-Anne). We assessed the disagreement between expert estimates and individuals’ perceptions of areas exposed to coastal flooding using sketch mapping indicators. We also determined the relationships between individuals’ living environments and the way they perceived the spatial extent of coastal flooding. Respondents were likely to under-assess the exposure of areas that are actually exposed according to expert hazard maps. Perceived distance to coastal flooding areas appeared to be a predominant factor in assessing individuals’ perceptions. Local preventive actions could take into account the individuals’ tendency to under-estimate the areas exposed to coastal flooding. Individual perception of the spatial extent of coastal flooding appeared to be more influenced by the perceived distance of the home to exposed areas than the objective distance. It is a result that raises the question about the individuals’ understanding of hazard maps and regulatory maps. This may necessitate the improvement of the appropriation of these documents by the inhabitants by involving them more closely in the application and decision process that directly concerns.

个人对法国四个沿海城市的沿海洪灾地区的认识：草图绘制的贡献

这项研究使用草图绘制方法，分析了个人对当地遭受沿海洪灾影响的地区的看法。这样，在法国的四个沿海城市（Barneville-Carteret，Saintes-Maries-de-la-mer，Châtelaillon-Plage和Sainte-Anne）对318人进行了调查。我们使用草图绘制指标评估了专家估计与个人对沿海洪灾地区的感知之间的分歧。我们还确定了个人生活环境与他们对沿海洪水的空间范围的认识之间的关系。根据专家的危害图，受访者可能未充分评估实际暴露区域的暴露程度。到沿海洪灾区的感知距离似乎是评估个人感知的主要因素。当地的预防措施可以考虑到个人低估了沿海洪灾地区的趋势。个人对沿海洪灾程度的感知似乎比目标距离更受房屋到裸露区域的感知距离的影响。结果引起了有关个人对危险图和法规图的理解的问题。这可能需要使居民更密切地参与直接涉及的申请和决策过程，以改善居民对这些文件的挪用。个人对沿海洪灾程度的感知似乎比目标距离更受房屋到裸露区域的感知距离的影响。结果引起了有关个人对危险图和法规图的理解的问题。这可能需要使居民更密切地参与直接涉及的申请和决策过程，以改善居民对这些文件的挪用。个人对沿海洪灾程度的感知似乎比目标距离更受房屋到裸露区域的感知距离的影响。结果引起了有关个人对危险图和法规图的理解的问题。这可能需要使居民更密切地参与直接涉及的申请和决策过程，以改善居民对这些文件的挪用。
