The thematic report on Estuaries as part of the Quality Status Report 2017 (QSR 2017) provides an overview of the present status of the estuaries in the Wadden Sea area, based on the Trilateral Monitoring and Assessment Program (TMAP) and further data sources from trilateral partners. This status review includes aspects like ecological status, assessment, protection and policy and management.

From the QSR 2009, thematic report on estuaries:

Estuaries can be defined as tidally influenced transition zones between marine and riverine environments. However, especially in defining the down- and the upstream border several approaches exist. In the following we include the freshwater tidal reaches as upstream border and the so called “transitional waters” according to the Water Framework Directive (WFD) as downstream border.
