High Parts of the Netherlands Higher Sand and Hilly Landscapes

Even in the higher parts of the Netherlands climate buffers are applicable. For example by closing the ditches of the brooks in the spring area and regeneration of the natural vegetation, the sponge function increases. This way, the peak discharges in the brooks can be lowered. Downstream, the natural flooding dynamic of the brooks can be restored if the land use at the edges of the brooks is made flood-proof. Beside that the brooks can be re-meandered in order to revitalise the natural erosion and sedimentation processes.

The Weerter forest is an example, where these principles are applied (Fig. 5.28). The drainage ditches are filled up and the discharge of water is hindered as much as possible. This will result in the storage of water upstream the brooks and a high quality peat and marshland nature will emerge. On top of that, much water is buffered in the area in case of extreme precipitation, which leads to less water annoyance in Den Bosch and Eindhoven downstream.
