Nevers High Flood Risk Area (RIA)

This dataset corresponds to Nevers Significant Flood Risk Territory (RIT) - version 2 (2020 vintage). The data have been compiled in accordance with the Flood Directive v2 standard: it is mainly an update of the 2013 reporting data. The dataset shall consist of: \- management zoning; \- zoning of flood-prone areas; \- zoning of water heights; \- the various challenges facing the territory; etc. The standard explaining the structure of the data is available below: Standard COVADIS DI v2 https://files.georisques.fr/di_2020/COVADIS_standard_DI_v2.1.pdf The 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 a flood risk management plan that aims to reduce the negative consequences of floods on human health, the environment, cultural heritage and economic activity.The objectives and requirements for implementation are given by the Law of 12 July 2010 on the National Commitment for the Environment (LENE) and the Decree of 2 March 2011. In this context, the primary objective of mapping flood surfaces and flood risks for IRRs is to contribute, by homogenizing and objectifying knowledge of the exposure of issues to floods, to the development of flood risk management plans (FRMPs). This data set is used to produce flood area maps and the flood risk map that represent flood hazards and exposed issues, respectively, at an appropriate scale. Their objective is to provide quantitative elements to assess more accurately the vulnerability of a territory for the three levels of flood probability (strong, medium, low).本数据集对应讷韦尔重大洪水风险领土（RIT）2020年发布的第2版。本数据集依据《洪水指令第2版》标准编制，核心为2013年报告数据的更新版本。数据集包含以下内容： - 管理分区； - 易涝区分区； - 水位分区； - 辖区面临的各类挑战等。 说明本数据集结构的标准可通过以下链接获取：COVADIS DI第2版标准，链接为：https://files.georisques.fr/di_2020/COVADIS_standard_DI_v2.1.pdf 2007年10月23日发布的欧盟《关于洪水风险评估与管理的2007/60/EC号指令》（收录于《欧盟官方公报》L 288号，2007年11月6日，第27页）重塑了欧盟全境的洪水预防战略，要求编制洪水风险管理计划（FRMPs），以减轻洪水对人类健康、自然环境、文化遗产及经济活动带来的负面影响。 该指令的实施目标与具体要求，由2010年7月12日发布的《国家环境承诺法》（LENE）以及2011年3月2日发布的政令予以明确。 在此背景下，针对IRRs开展洪水淹没范围与洪水风险制图的核心目标，是通过统一化与客观化梳理各类风险要素的洪水暴露认知，助力洪水风险管理计划（FRMPs）的编制工作。 本数据集可用于生成适配特定比例尺的洪水淹没范围图与洪水风险图，二者分别对应洪水灾害风险与受影响的各类风险要素。此类地图的核心目标是提供量化支撑数据，以更精准地评估三种洪水概率等级（高、中、低）下的辖区脆弱性。
