Territories at significant flood risk (TRI BASSE-TERRE) — Iso zone height class

An area for which a hazard of a certain type under a certain scenario causes a rise of water whose height is within a fixed range of values. A height class iso area is an area for which all water heights are within the same height range. A height class iso area is characterised by its spatial extension and the minimum and maximum terminals of the height range. Data sets produced by the GIS Flooding Directive at a significant risk of flooding (TRI) of Guadeloupe and mapping for reporting purposes for the European Flood Directive. 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 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 realignment 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 areas and flood risks for IRRs is to contribute, by homogehising and objecting knowledge of the exposure of issues to floods, to the development of flood risk management plans (FRPs). This series of data is used to produce the flood maps and the flood risk map that take the flood aleases and the stakes respectively expose to an appropriate scale. Their objective is to provide quantitative information to assess more finely the vulnerability of a territory for the three levels of probabilistic flooding (high, medium, low). The IRRs adopted in the context of the 1st cycle of the Flood Directive are defined as follows: Sort “Centre” Les Abymes — Baie-Mahault — Le Gosier — Le Moule — Morne-à-l’Eau — Pointe-à-Pitre — Sainte-Anne.
