Aquitaine: Pau Sorting — Water Height Zones, Flood Directive

Tables of areas where a hazard of a certain type under a certain scenario causes a rise of water with a height within a fixed range of values, 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 2007 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).

本数据集为满足《欧洲洪水指令》的报告编制需求而生成，涵盖特定场景下特定类型洪水灾害致使水位处于固定区间内上涨的区域表格。2007年10月23日发布的《欧洲议会与理事会关于洪水风险评估与管理的2007/60/EC号指令》（载于《欧盟官方公报》2007年第L288号，2007年11月6日，第27页），对欧洲地区的洪水防治战略具有指导性意义。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、生态环境、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要求，在2010年7月12日发布的《国家环境承诺法》（LENE）及2011年3月2日的政令中予以明确。在此框架下，洪水与洪水风险区划（IRRs）的核心目标，是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。本数据集可分别用于生成洪水淹没地图与洪水风险地图，以恰当的比例尺分别表征洪水灾害与暴露的风险要素。二者的核心目标是提供量化依据，以进一步评估区域在高、中、低三级洪水发生概率下的脆弱性。
