Flood directive — Height iso zone — extreme scenario (4) — TRI Vallées de la Vienne and Clain in the agglomeration of Châtellerault

a series of geographical data produced by the GIS Flooding Directive for the territory at significant risk of flooding (TRI) of Vallées de la Vienne and du Clain in the agglomeration of Châtellerault and mapped for reporting purposes for the European Flood Directive. The European Directive 2007/60/EC of 23 October 2007 on the risk assessment and management of the risks of #x27; flooding (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 and heritage cultural and economic activity. The objectives and requirements for achievement 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 the mapping of flood surfaces and risks of #x27; flooding for IRRs is to contribute, by homogenising and objecting knowledge of ' exposure of issues to floods, to the development of flood risk management plans (IFMPs). This dataset is used to produce flood surface maps and flood risk maps that represent flood hazards and issues on an appropriate scale, respectively. Their objective is to provide quantitative elements to assess the vulnerability of a territory more accurately for the three levels of flood probability (high, medium, low). __Origin__ The digitised data is largely derived from the TOPO -IGN BD, The accuracy of the stakes is therefore that of the data source. __Partner organisations__ DREAL Nouvelle-Aquitaine __Links annexes__ * [basketDownloadFrontalParametrage](https://catalogue.sigena.fr/geosource/panierDownloadFrontalParametrage?LAYERIDTS=10964) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/817a8fbd6749cf728886b74cbed239b98c3febb5)
