Dataset Direct Download Service (WFS): Reference profiles for the flooding of the centennial flood of the Épernay sector

During hydraulic modelling, the centennial flood hazard was determined on the area. In addition to the envelope of this hazard, the water levels over the entire sector could be determined. In order to visualise these water heights, a set of profile, known as “reference profiles”, was positioned with an altimeter deviation of about 25 cm. All of these ratings are linked to the General Level of France and are expressed in NGF meter. Genealogy: The reference profiles are represented on the graphic documents. They are represented by open polylines with a rating in NGF meter. These ratings will determine the regulatory ratings used in the interpretation of the future IPP Regulations. The profiles are located throughout the PPRi sector.
