Reference for water bodies of rivers of the Seine-Normandie basin

The Water Framework Directive (WFD) sets out the basic principles for sustainable water policy. Its purpose is to establish a framework for the protection of inland surface waters, transitional waters, coastal waters and groundwater. The WFD aims to achieve good water status. The body of water is the elementary territorial division of aquatic environments intended to be the WFD assessment unit. A reference for water bodies is established for all waters in the Seine Normandy basin. It allows the development of the WFD management plan to achieve good water status. This data concerns the Master Plan for Water Management 2022-027 (SDAGE) of the Seine Normandy Basin. It lists the surface water bodies: river body, transitional water body, coastal water body, body of water body water body A river water body is a distinct and significant part of surface waters such as a river, river or canal, part of a river, river or canal. A transitional water body is a distinct and significant part of surface waters located near the mouths of rivers or rivers, which are partly salty because of their proximity to coastal waters but which remain fundamentally influenced by fresh water currents. A coastal water body is a distinct and significant part of the surface waters between the baseline used to measure the breadth of territorial waters and a distance of one nautical mile. A body of water body of water is a distinct and significant part of surface waters such as a lake, a reservoir.
