Flood Directive — zoning of the area with significant flood risk (TRI) Vienna and Clain valleys in the agglomeration of Châtellerault

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).本数据集为一套空间数据，由针对沙泰勒罗集聚城区内维也纳河谷与克兰河谷高洪水风险区域（TRI）的地理信息系统（Geographic Information System，GIS）洪水指令生成，且按照《欧洲洪水指令》的报告要求完成制图。 2007年10月23日发布的《欧盟议会与理事会2007/60/EC号指令》（见于《欧盟官方公报》L系列第288号，2007年11月6日，第27页）对欧洲的洪水防治策略产生了深远影响。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、文化遗产以及文化与经济活动造成的负面影响。 相关目标与实施要求已在2010年7月12日发布的《国家环境承诺法》（LENE）以及2011年3月2日的政令中予以明确。在此背景下，为高洪水风险区域（TRI）编制淹没区域与洪水风险图的核心目标，是通过统一并整合受洪水影响对象的相关认知，助力洪水风险管理计划（IFMPs）的编制工作。 本数据集用于制作洪水淹没图与洪水风险图，二者分别以适宜比例尺表征洪水危险性与受影响对象。其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。
