Flood Directive — Iso zone height class — extreme scenario (4) — TRI de Saintes — Cognac — Angoulême, overflow of the Charente

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）区域地理信息系统（GIS）洪水指令所生成的系列空间数据，涵盖夏朗德河（Charente）泛滥情况，且为满足欧盟洪水指令的报告需求完成制图。 2007年10月23日发布的欧盟指令2007/60/EC（《关于洪水风险评估与管理指令》）（刊载于《欧盟官方公报》L 288号，2007年11月6日，第27页）对欧洲的洪水防控策略产生了深远影响。该指令要求编制洪水风险管理计划，旨在减轻洪水对人类健康、环境、文化遗产及经济活动的负面影响。 上述指令的目标与实施要求已在2010年7月12日《国家环境承诺法》（LENE）及2011年3月2日的政令中予以明确。在此背景下，为TRIs编制洪水淹没范围与洪水风险制图的首要目标，是通过统一认知并夯实对各类受影响事项的洪水暴露情况的相关知识，助力综合洪水管理计划（Integrated Flood Management Plans，IFMPs）的制定。本数据集用于生成洪水淹没范围图与洪水风险图，二者分别以适配比例尺展示洪水灾害与受影响对象。其目标在于提供量化依据，以针对高、中、低三级洪水发生概率下的区域脆弱性开展进一步评估。
