Flood Directive — The issue of the heritage of the territory at significant flood risk (TRI) Vienna and Clain Valleys in the agglomeration of Châtellerault (surface)

a series of spatial data produced by the GIS Flood Directive on the High Flood Risk Area (TRI) of the Vienna and Clain Valleys in the agglomeration of Châtellerault and mapped for reporting purposes for the European Flood Directive. European Directive 2007/60/EC of 23 October 2007 on the assessment and management of flood risks (OJ L 288, 06-11-2007, p. 27) influences the flood prevention strategy in Europe. It requires the production of flood risk management plans aimed at reducing the negative consequences of flooding on human health, the environment and heritage. cultural and economic activity. The objectives and implementation requirements are set out in the Law of 12 July 2010 on the National Commitment for the Environment (LENE) and the Decree of 2 March 2011. In this context, the primary objective of mapping floodable surfaces and flood risk for TRIs is to contribute, by homogenising and objecting to knowledge of the exposure of issues to floods, to the development of flood risk management plans (IFMPs). This data set is used to produce flood surface maps and flood risk maps that represent flood hazards and issues at an appropriate scale, respectively. Their objective is to provide quantitative evidence to further assess the vulnerability of a territory for the three levels of probability of flooding (high, medium, low).本数据集为基于地理信息系统（GIS）洪水导则生成的一系列空间数据，覆盖沙泰勒罗（Châtellerault）集聚区境内维也纳河谷与克兰河谷的高洪水风险区（TRI，High Flood Risk Area），并为《欧盟洪水指令》的报告编制工作完成制图。 2007年10月23日发布的《欧盟洪水风险评估与管理指令2007/60/EC》（官方公报L 288，2007年11月6日，第27页）对欧洲洪水防控战略具有指导意义。该指令要求编制洪水风险管理计划，以减轻洪水对人类健康、环境、文化遗产及经济活动造成的负面影响。 相关目标与实施要求在2010年7月12日发布的《国家环境承诺法》（LENE）及2011年3月2日发布的政令中予以明确。在此背景下，针对TRI编制洪水淹没范围与洪水风险图的核心目标，是通过统一并整合对洪水影响对象的认知，助力综合洪水管理计划（IFMPs，Integrated Flood Management Plans）的编制。 本数据集用于制作洪水淹没范围图与洪水风险图，二者分别以适宜比例尺表征洪水灾害与受影响对象。上述地图的目标是提供量化依据，以进一步评估某一区域在高、中、低三种洪水发生概率下的脆弱性。
