Perimeter of the Flood Risk Territories (TRI) — Cycle 2 (2020) of the Rhine-Meuse Basin

The identification of areas with significant flood risk (TRI) is based on the results of the Preliminary Flood Risk Assessment (EPRI), carried out at the level of each river basin district. It is also based on the national criteria for characterising the importance of the flood risk, as defined in the Ministerial Order of 27 April 2012, and takes into account, where appropriate, local particularities, such as the dangerous nature of the flood and any other local factors likely to aggravate the potential negative consequences associated with floods for human health, the environment, property including cultural heritage and economic activity. The list of IRRs drawn up by the competent authority at this scale, the Basin Coordinating Prefect. With a high urban population density, IRRs receive special attention from public authorities to reduce the cost of flood damage. To this end, the 12 IRRs identified in 2012 (cycle 1 of the Flood Directive) in the Rhine-Meuse Basin are subject to: — a mapping of the risks to flood phenomena characterising the territory; — local flood risk management strategies at the level of the watersheds concerned A “DISTRICT” field has been added to the GIS layer so that the different river basin districts including IRRs can be discerned.
