Dataset Direct Download Service (WFS): Aquitaine: Sorting of Tonneins-Marmande — Objects describing the right-of-way and the useful characteristics of the flood-risk territory, Flood Directive

Table containing an object describing the right-of-way and useful characteristics of the flood risk territory produced 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, cultural heritage and economic activity.The objectives and requirements for implementation are set out in the Law of 12 July 2010 on a national commitment for the environment (LENE) and the decree of 2 March 2011. In this context, the primary objective of flood and flood risk mapping for IRRs is to contribute, by homogenising and objectivating knowledge of flood exposure, to the development of flood risk management plans (PGRIs).This dataset is used to produce flood surface maps and flood risk maps, respectively, representing flood hazards and issues exposed on an appropriate scale. 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).

本数据集以表格形式收录了为满足欧洲洪水指令（European Flood Directive）报告编制需求而生成的洪水风险区域通行权及实用特征描述对象。2007年10月23日发布的《欧洲议会与理事会2007/60/EC号指令：洪水风险评估与管理》（官方公报L 288，2007年11月6日，第27页）对欧盟防洪战略具有深远影响。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、自然环境、文化遗产及经济活动造成的负面影响。相关实施目标与要求已在2010年7月12日发布的《国家环境承诺法》（LENE）及2011年3月2日的政令中作出明确规定。在此框架下，洪水风险区域（IRRs）的洪水与洪水风险制图工作的核心目标，是通过统一化与客观化洪水暴露相关认知，助力洪水风险管理计划（PGRIs）的制定。本数据集分别用于制作洪水淹没范围图与洪水风险图，二者分别对应特定比例尺下的洪水危险性与暴露风险要素。二者的目标是提供量化依据，以进一步评估某区域在三级洪水发生概率（高、中、低）下的脆弱性。
