Map Viewing Service (WMS) of the dataset: Flooding areas established by hydrogeomorphological methods in Lorraine and on the administrative district of the Rhine-Meuse basin

The dataset contains flood areas established by hydrogeomorphological methods in Lorraine and on the Rhine-Meuse Basin Administrative District In Lorraine and on the administrative district of the Rhine-Meuse basin, when they were produced. ** Hydrogeomorphological flood: Maximum flooding area defined by the study of fluviatile hydrosystems. The demarcated area includes the minor bed, the major bed and the exceptional major bed of the watercourse. It corresponds to the flooding field of exceptional floods. VERBATIM: The flood zone atlas consists of three types of zoning: (the modelled centennial flood,the surface obtained by the hydrogeomorphological method, historical floods. The latter result from different methods and therefore have a different meaning. Any exploitation or representation of these data must be made knowingly with a distinction between the different zonings. Data produced on the Large Flood Risk Territories (HRT) under the Flood Directive have not been added to previously produced Flood Hazardous Area Atlas (AZI) data. They should be added to supplement the AZI. DATA QUALITY: The data are an aggregation of different data at various scales. The accuracy of the source data is indicated in the attributes.
