New-Aquitaine: Basque Coast Sorting (overflow hazard) — Table listing flood maps produced on a given IRR, Flood Directive.

This data set contains flood maps produced on the IRR, 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).

本数据集包含针对IRR编制的洪水图件，其编制目的是为满足《欧洲洪水指令》的报告需求。2007年10月23日发布的《关于洪水风险评估与管理的2007/60/EC号指令》（刊载于《欧盟官方公报》L 288期，2007年11月6日，第27页）对欧盟的防洪战略具有指导意义。该指令要求制定洪水风险管理计划，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。
欧盟层面的实施目标与要求，在2010年7月12日出台的《国家环境承诺法》（LENE）以及2011年3月2日发布的政令中予以明确。在此框架下，针对IRR开展洪水与洪水风险制图的核心目标，是通过实现洪水暴露相关认知的标准化与客观化，为洪水风险管理计划（PGRIs）的制定提供支撑。
本数据集可分别用于编制洪水淹没范围图与洪水风险图，二者分别表征特定比例尺下的洪水危险性与暴露风险。其目标是提供量化依据，以进一步评估某一区域在高、中、低三种洪水概率等级下的脆弱性。
