Climate change and rising sea level will certainly lead to significant changes in the management of low-lying coastal areas in the coming decades. While the most recent studies in the field of coastal storms-related flooding are increasingly integrated, simultaneously addressing hazards and vulnerability, as well as population risk perception, there is still little work to consider the preparedness of stakeholders to manage crises whose frequency and intensity are likely to increase in the next years. The aim of this paper is to expose the major results of the CRISSIS research program, which proposed a multi-disciplinary approach to the management of coastal flood risk in a town particularly exposed on the French Mediterranean coast. The originality of the project was to offer both an integrated approach to risk by analysing its 3 dimensions (hazard, impact and vulnerability, and representations and perceptions held by populations and stakeholders, or « risk culture ») and a very operational section focused on the evaluation of crisis management measures led by local stakeholders. To achieve this objective, two crisis exercises were organized, the first one to test the assimilation by the municipality staff of existing crisis management procedures and the second to allow local actors to integrate in their crisis management procedures the new risk knowledge data issued from research conducted under the program. The project has had three main features; (i) it accurately mapped the submersible areas that present a critical vulnerability, both material and human; (ii) it revelated the poor social representation of marine submersion risk, as well as the obvious lack of awareness of crisis management systems and tools and the behavior to adopt in the event of flooding; (iii) Finally, it highlighted the need, through the crisis exercises, for a better assimilation by the municipality staff of the crisis management procedures defined in the Municipal Rescue Plan. The CRISSIS project has demonstrated the usefulness of an integrated and operational approach of coastal flood risk, not only in terms of studying hazards, stakes and vulnerability, but also in terms of crisis management, in particular through the organisation of crisis simulation exercises.

沿海洪灾风险：改善运营响应能力，以法国朗格多克的吕卡特市为例

在未来几十年中，气候变化和海平面上升必将导致低洼沿海地区的管理发生重大变化。尽管与沿海风暴有关的洪水领域的最新研究日益融合，同时解决了灾害和脆弱性以及对人口风险的认识，但仍然没有什么工作可以考虑利益相关者为应对危机的频率和强度而做好的准备未来几年可能会增加。本文的目的是揭示CRISSIS研究计划的主要结果，该计划提出了一种多学科方法来管理特别是法国地中海沿岸的一个城镇的沿海洪灾风险。该项目的独创性是通过分析风险的三个维度（危害，影响和脆弱性以及人口和利益相关者持有的表示和看法，或称为“风险文化”）来提供一种综合的风险管理方法，以及一个专门针对风险的操作性部分。评估由当地利益相关者领导的危机管理措施。为了实现这一目标，组织了两次危机演习，第一个是测试市政人员对现有危机管理程序的同化作用，第二个是允许本地参与者将其研究中发布的新的风险知识数据整合到他们的危机管理程序中。根据该计划。该项目具有三个主要功能；（i）准确地绘制出存在重大脆弱性的潜入区域，无论是物质上还是人为上；（ii）揭示出社会对海洋淹没风险的代表不力，以及明显缺乏对危机管理系统和工具的认识以及在发生洪水时应采取的行为；（iii）最后，它强调需要通过危机演习，使市政工作人员更好地吸收《市政救援计划》中规定的危机管理程序。CRISSIS项目已经证明了沿海洪水风险的综合性和可操作性方法的有用性，不仅在研究危害，风险和脆弱性方面，而且在危机管理方面，特别是通过组织危机模拟演习，都是如此。显然缺乏对危机管理系统和工具的认识，以及在发生洪灾时应采取的行为；（iii）最后，它强调需要通过危机演习使市政工作人员更好地吸收《市政救援计划》中规定的危机管理程序。CRISSIS项目已经证明了沿海洪水风险的综合性和可操作性方法的有用性，不仅在研究危害，风险和脆弱性方面，而且在危机管理方面，特别是通过组织危机模拟演习，都是如此。显然缺乏对危机管理系统和工具的认识，以及在发生洪灾时应采取的行为；（iii）最后，它强调需要通过危机演习使市政工作人员更好地吸收《市政救援计划》中规定的危机管理程序。CRISSIS项目已经证明了沿海洪水风险的综合性和可操作性方法的有用性，不仅在研究危害，风险和脆弱性方面，而且在危机管理方面，特别是通过组织危机模拟演习，都是如此。
