The Province of Zeeland has implemented a number of restoration projects in the Westerschelde with measures outside the dikes. These measures are mainly aimed at expanding and improving the quality of low-dynamic nature by constructing groins or adapting channels. This type of nature restoration is being implemented in five areas. Monitoring is important to evaluate the ecological effects of measures taken outside the dikes. The overarching research objective of this project is to answer the question: Do the flow velocities and sedimentation processes in the project areas develop in such a way that valuable low-dynamic nature is created within the project areas?
