The dataset contains the modelled historical flood envelope of the main rivers of Lorraine. In Lorraine when they were produced: Historical flood: Areas exposed to historical flooding observed in the past 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.
