New-Aquitaine: Sorting of Libourne (marine submersion) — Flooding areas, Flood directive

Table of flooding areas (area to be flooded in case of flooding of a certain type under a certain scenario), 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 aim is to provide quantitative evidence to better assess the vulnerability of a territory for the four levels of flood probability (high, medium, medium, low).

洪水淹没区域表（即特定场景下某类洪水暴发时将被淹没的区域），系为满足《欧洲洪水指令》的报告编制需求所生成。2007年10月23日发布的《欧盟2007/60/EC号关于洪水风险评估与管理的指令》（《欧盟官方公报》L 288，2007年11月6日，第27页）对欧洲的洪水防治战略具有重要指导意义。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。2010年7月12日《国家环境承诺法》（LENE）以及2011年3月2日的相关政令，明确了该指令的实施目标与具体要求。在此框架下，洪水与洪水风险制图（IRRs）的核心目标在于，通过统一并客观化洪水暴露风险的相关认知，助力洪水风险管理计划（PGRIs）的编制工作。本数据集分别用于制作洪水淹没范围图与洪水风险图，以适宜比例尺呈现洪水灾害与暴露风险要素。其核心目的在于提供量化依据，以便针对高、中、中、低四级洪水发生概率，更精准地评估对应区域的脆弱性。
