Masses d'eau cours d'eau - whole France - Version Rapportage 2010

A body of river water is a distinct and significant part of surface waters such as a river, a river or a canal, a part of a river, a river or a canal, constituting the elementary division of aquatic environments intended to be the unit of assessment of the WFD.

River water bodies are derived from the BDCarthage® v3 hydrographic theme of the BDCarto®.

The criteria for constructing river water bodies are:
- A body of water belongs to a single hydroecoregion
- The dominant fish population based on the fish context (Salmoniculture, Cyprinicole, Intermédiaire)
- Size class (strahler confluence row)

The water body code is structured as follows:
Water body type code + Basin code (district as defined in dce) + Increment
