Water — Warning zone for surface waters during droughts in Loir-et-Cher

This layer is used to feed a national layer. It is produced locally in each DDT and then assembled at regional level before transmission at the national level (Water and Biodiversity Directorate). As the management of drought orders is departmental, the alert zones will all stop at departmental boundaries. The interdepartmental areas will be “cut” and bear a name as close as possible. The superficial alert zones will not overlap under any circumstances. — name of fields: 1) Id: Identifier consisting of characters, in the form <[INSEE code of the region] >_<[NiNsee Dpt]>_<[Ndorder]> this identifier must be unique (A each field corresponds to one code and only one), and no duplication of the latter. 2) Dpt: No of department No. Insee of the department consisting of 2 digits for the departments of metropolis, with the exception of the departments of Corsica 2A and 2B. 3) Libel_ZA_ESU (or Libel_ZA_ESO) alerte:constitué characters, in the form “X basin”, “X table”, “X basin from A to B”, etc.
