The greatest challenge facing the Berkel is to restore structural variation with alternating deep and shallow water, natural river banks, and thereby variation in current. To achieve this target, in this vision we decided to make the Berkel shallower to reduce the cross-section of the profile. To accommodate the river better in the landscape, with vegetation inside the embankments, the embankments have to be moved. We tried to follow the natural elevations of the landscape as much as possible in moving the embankments, or if they are high enough, to use these elevations as a natural barrier. Since the embankments have to be moved, the side channels that are currently in the zone and provide drainage must be adapted too. This creates an opportunity to allow the side channels to follow a more natural course and at the same time to give the farmers more land beside the river.
