Aquitaine: Bergerac Sorting — Flood Zones, 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 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).洪水区域表（即特定情境下特定类型洪水暴发时的受淹范围），为落实《欧洲洪水指令》(European Flood Directive)的报告工作编制而成。2007年10月23日发布的欧盟第2007/60/EC号指令《关于洪水风险评估与管理》（官方公报L 288，2007年11月6日，第27页）对欧洲洪水防治战略具有深远影响。该指令要求编制洪水风险管理计划，旨在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。本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》(Law of 12 July 2010 on a national commitment for the environment, LENE)及2011年3月2日的政令中予以明确。在此框架下，洪水与洪水风险制图（IRRs）的首要目标是通过统一化、客观化洪水暴露风险的认知基础，为洪水风险管理计划（PGRIs）的编制提供支撑。本数据集可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受暴露对象的分布情况。其核心目标是提供量化依据，以进一步评估某一区域在高、中、低三种洪水发生概率下的脆弱性水平。
