Administrative DCE Sub-Bassins

The administrative DCE sub-basin is an intermediate level of aggregation between the water body and the DCE basin. It was implemented at the end of 2008 at the request of the European Commission for reporting and visualisation objectives within WISE (Water Information System for Europe).

In France, the administrative DCE sub-basin is defined as the area of competence of the territorial commissions.

The only exceptions to the rule for dividing DCE basins into administrative DCE sub-basins are, in metropolitan France, the DCE basins: A, B1, B2, E and DOM-TOM. For them, the administrative DCE sub-basin is equal to the DCE basin.

The administrative DCE sub-basin is derived from the BDCarto® administrative theme.
Its cartographic representation is the aggregation of the polygons of the municipalities composing it.
The geographical coverage is National (Metropolitan France + DOM).
