Observed Behavior in a Nutshell

The pilot Sand Motor involved constructing a large peninsula of about 2 km alongshore, with the most seaward position protruding about 1 km into the sea. The main part is a hook-shaped peninsula with the outer tip curved towards the north. The crest of the peninsula rises to 5 m above mean sea level. This design and location best fulfilled the multidisciplinary and multi-stakeholder requirements of safety in combination with recreation, development of nature, and scientific innovation. The cross-shore slope of the peninsula is 1:50, so that the toe of the nourishment is at -8 m NAP and ~1500 m from the original coastline. The northern tip of the peninsula creates a sheltered area that nurtures different biotic species. A small lake of about 8 hectares was designed to prevent the freshwater lens in the dunes from migrating seaward, which would endanger groundwater extraction from the existing dune area.
