Flood Directive — High-class iso zone — medium scenario (2) — TRI Vallées de la Vienne and Clain in the agglomeration of Châtellerault

a series of spatial data produced by the GIS Flood Directive on the High Flood Risk Area (TRI) of the Vienna and Clain Valleys in the agglomeration of Châtellerault and mapped 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 and heritage. cultural and economic activity. The objectives and implementation requirements are set out in 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 floodable surfaces and flood risk for TRIs is to contribute, by homogenising and objecting to knowledge of the exposure of issues to floods, to the development of flood risk management plans (IFMPs). This data set is used to produce flood surface maps and flood risk maps that represent flood hazards and issues at an appropriate scale, respectively. 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).
