New-Aquitaine: Bordeaux Sorting (overflow hazard) — 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呈现，包含为满足《欧洲洪水指令》报告编制需求所生成的、用于描述洪水风险区域通行权限与实用特性的各项数据对象。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的指令》，刊载于《欧盟官方公报》L系列第288号，2007年11月6日，第27页），对欧盟全域的洪水防控战略产生了深远影响。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、自然环境、文化遗产及经济活动造成的负面影响。该指令的实施目标与相关要求，在《2010年7月12日国家环境承诺法》（LENE）及2011年3月2日颁布的政令中作出了明确规定。在此背景下，针对IRRs开展洪水与洪水风险制图工作的核心目标，是通过统一并客观化洪水暴露相关认知，助力洪水风险管理计划（PGRIs）的编制。本数据集可分别用于生成洪水淹没范围图与洪水风险图，前者表征洪水灾害风险，后者以适宜比例尺展示各类暴露风险对象。二者的核心目标是提供量化依据，以针对高、中、低三个概率等级的洪水场景，进一步评估区域的洪水脆弱性。
