The Ministry of Public Security (MSP) supports the development of knowledge of flood risks. Flood markers make it possible to illustrate the water level reached during a very major flood and thus to raise public awareness of the risks associated with it while maintaining this awareness of risk in the collective memory. What is a flood marker? __ A flood mark is a physical mark (15 cm in diameter for the standard) testifying to the maximum level reached by a watercourse during a very significant flood on a given date. The flood marker is usually located at a permanent location and is easily visible to everyone, for example on the wall of a building or on a dedicated pole. __Point data set “Flood references” __ The point data set “Flood markers” contains, for each coordinate system, the location, the date of the reference flood and the maximum water level reached. The list of all attributes is provided in the dataset description sheet (Additional Information section). Despite the quality of the work carried out, the Ministry of Public Security cannot guarantee the absence of errors in the data. __Related datasets The “Flood Water Levels” dataset produced by the Ministry of Public Security also contains maximum water levels reached during a flood. The link to this dataset is provided in the Documentation section.This third party metadata element was translated using an automated translation tool (Amazon Translate).
