Hydrographic areas of the BD CARTHAGE in Burgundy-Franche-Comté
Description
Extraction of the hydrographic areas of the BD Carthage France in the territory of the Burgundy-Franche-Comté region. This data is neither downloadable nor reapable on the IDEO BFC platform. Refer to the SANDRE metadata sheet: http://www.sandre.eaufrance.fr/atlas/srv/fre/catalog.search#/metadata/67e5bc6c-016d-4037-83b6-2043e7972772 Circular No. 91-50 of 12 February 1991 on the hydrographic coding and spatial identification of surface aquatic environments in metropolitan France defines the hydrographic zone as follows: The entire French territory is divided into elementary zones called hydrographic zones. Their boundaries are based on those of topographical watersheds (in whole or in part)”. A zone is a partition of a subsector that can have up to 10. It is entirely within a river basin boundary and serves, along with other elements, for the delimitation of various programming or regulatory areas such as Water Planning and Management Schemes, sensitive areas, water bodies mentioned in the European Framework Directive of 23 October 2000. A hydrographic area covers, in part or in whole, the territory of one or more municipalities. Conversely, the territory of a municipality is either fully included within a hydrographic zone or split between several zones. Different scenarios of the river basin area may exist: a — The main river of the river basin area originates within the area: it is an upstream area whose contour corresponds to that of the topographical catchment area of the main stream at the exit point of the zone. b — The hydrographic area is crossed by the main watercourse and the pk at the downstream point is not 1000: it is an intermediate watershed, c — The hydrographic area is crossed by the main stream whose downstream point corresponds to pk 1000: this is the downstream area of the watershed, d — The hydrographic area is bordering the coastline. Three scenarios: * or it is a main stream that has its source in the area: this is the case (a), * or this downstream area is the last intermediate basin before the mouth of the main river: this is case (c), * or the area includes a line of the coastline with the mouth of the coastal river and areas drained by “rus” throwing directly into the sea, e — The area does not have surface flow but nevertheless receives endoreic streams upstream. The list of river basin areas shows two specific cases: \- To avoid the creation of border river regions, five hydrographic areas located on the borderline with Italy or Spain (codes Y670 and Y680 corresponding to two upstream ends of the Po basin, S910, S911 and S912) have been attached to the coastal hydrographic regions (codes S and Y) of the basin districts on which they depend, \- Although the river logic would require that the zone U204 (Juzgnena sub-basin belonging to the Rhine basin) be attached to the Rhine-Meuse basin district, it is nevertheless attached to the Rhone-Méditerranée-Corse basin (Saône hydrographic region) given the small size of this area and its remoteness from the Rhine-Meuse basin, \- Although the hydrographic logic would require the areas of sector D0 (Sambre Basin in France) to be assigned to region B (Meuse basin) they are administratively attached to the district of Artois Picardie basin given the remoteness of the Meuse and Sambre basins in France and the confluence of these two rivers that operate abroad.
