Groundwater pool in 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 2022-2027 (SDAGE) of the Seine Normandy Basin. It lists groundwater bodies

水框架指令（Water Framework Directive，WFD）阐明了可持续水政策的基本原则，其宗旨为构建覆盖内陆地表水、过渡水域、近岸海域及地下水的保护框架，旨在实现良好水环境状态。
水体是水生环境的基本地域划分单元，同时作为WFD的评估单元。塞纳-诺曼底流域内所有水域均已建立水体参考基准，可为制定WFD水环境管理计划以达成良好水环境状态提供支撑。
本次数据集涉及塞纳-诺曼底流域2022-2027年水资源管理总体规划（Master Plan for Water Management 2022-2027，SDAGE），该规划收录了流域内全部地下水体。
