Depolder

Depoldering means giving land back to the river. First, we construct a new levee inland. Then we make openings in the old levee, creating additional room between the old and the new levee where the river can (over)flow. This reduces the power of the water and the water level of the river while limiting the risk of flooding in the region. The tides are given free rein again, which results in the resurgence of valuable tidal nature.
