Flood Directive — The issue of the heritage of Saintes — Cognac — Angoulême, overflow of the Charente (one-off)

A series of spatial data produced by the GIS Flood Directive of Saintes — Cognac — Angoulême, overflow of the Charente 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).本数据集为桑特（Saintes）—干邑（Cognac）—昂古莱姆（Angoulême）区域夏朗德河（Charente）漫溢场景下，由地理信息系统洪水指令（GIS Flood Directive）生成的一系列空间数据，且为满足欧洲洪水指令（European Flood Directive）的报告需求完成制图。 2007年10月23日发布的《欧盟2007/60/EC号指令：洪水风险评估与管理》（欧盟官方公报L 288，2007年11月6日，第27页）对欧洲洪水预防战略产生了重要影响。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》（Loi sur l'Engagement National pour l'Environnement，简称LENE）以及2011年3月2日发布的政令中予以明确。 在此框架下，为受影响对象（TRIs）绘制洪水淹没范围与洪水风险图的首要目标，是通过统一并规范洪水影响相关认知，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。其核心目标是提供量化依据，以针对高、中、低三级洪水发生概率，进一步评估某一区域的洪水脆弱性。
