Lesson learned: adaptive management is needed with adaptive and removable constructions. For example, start with rather low groynes and heighten the groynes in case the sedimentation is not sufficient. Also, when building groynes the local morphology around the area has to be considered.

Crux of the matter
A positive lesson was that the planning of the project and the choice of the measure has been carried out in cooperation with all competent authorities therefore involving all available knowledge on a variety of aspects early on in the project. Hydromorphological models were used during the planning stage to analyse different configurations of groynes and the configuration with the least morphological impact was selected.Lesson learned: adaptive management is needed with adaptive and removable constructions. For example, start with rather low groynes and heighten the groynes in case the sedimentation is not sufficient. Also, when building groynes the local morphology around the area has to be considered.
