Planning and design
The basic idea of the Workumerbuitenwaard project was that the sand bar would gradually erode and move shoreward, which in turn would lead to onshore sand transport and protection of the coast and the shellfish reefs. Sedimentation should further create new room for wetland and reed vegetation and a new habitat for a variety of species.
Project Solution
The sand nourishment consisted of a sand bar 450 m offshore. The top of the sand bar was meant to remain submerged soon after placement and the bar had no artificial protection.
