Aquitaine: Sorting of the Basque Coast (overflow hazard) — Geolocation data produced by the GIS Flood Directive of the Basque Coast at Risk of Flooding.

The IRR flood and flood risk maps were approved on 03 December 2014 by Prefectural Order No 2014337-0002. The geostandard Flood Directive describes the basis of geographical data produced on territories with significant flood risk (TRI) 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 by requiring the production of flood risk management plans for each river basin district. Article 1 of the Flood Directive specifies its objective of establishing a framework for the assessment and management of flood risks, which aims to reduce the negative consequences of flooding on human health, the environment, cultural heritage 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 flood and flood risk mapping for TRIs is to contribute, by homogenising and objectivating knowledge of flood exposure, to the drafting of flood risk management plans (WRMs), to the definition of the objectives of the plan and to the development of local strategies by TRI. Thus, the purpose of this geostandard is to: 1. homogenise the production of data used for flooding and flood risk maps, 2. facilitate the implementation of a GIS on each IRR. This Flood Directive GIS should become a living reference for knowledge of hazards and flood risks on these IRRs and will be used to establish flood risk management plans. IRR GIS will be integrated into a common national GIS.
