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

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

The criteria for the realisation of river water bodies are:
— A body of water belongs to a single hydroecoregion
— The dominant fish population based on the fish context (Salmoniculture, Cypriniculture, Intermediate)
— Size class (strhler confluence row)

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