New-Aquitaine: Basque Coast Sorting (overflow hazard) — Water Height Zones, Flood Directive

This dataset contains areas where a hazard of a certain type under a certain scenario causes a rise of water at 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).

本数据集涵盖特定情景下某类灾害引发水位处于固定数值区间上涨的区域，系为《欧洲洪水指令》（European Flood Directive）的报告编制需求而生成。2007年10月23日发布的《欧洲议会与欧盟理事会2007/60/EC号指令》（关于洪水风险评估与管理，OJ 2007 L 288, 2007年11月6日，第27页）对欧盟的防洪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、自然环境、文化遗产及经济活动造成的负面影响。其实施目标与要求在2010年7月12日颁布的《国家环境承诺法》（Law of 12 July 2010 on a national commitment for the environment，简称LENE）及2011年3月2日发布的政令中予以明确。在此框架下，针对IRRs开展的洪水与洪水风险图编制工作的核心目标，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，前者表征洪水灾害，后者展示特定尺度下的暴露风险要素。二者的目标在于提供量化依据，以进一步评估某一区域在高、中、低三级洪水发生概率下的易损性。
