Current challenges in coastal management in the Netherlands: examples of pilot projects

A need for upscaling of sand nourishments to guarantee sustainable conditions for safety against flooding and preservation of coastal functions, combined with the need to enhance an integrated coastal zone management in the Netherlands, has initiated a number of pilot experiments. The management background and the approach leading to the pilots are illustrated. Central to the approach is a connection between large scale requirements and small scale needs, applying a concept of Building-with-Nature. The three pilots illustrate different applications; two for mega-scale nourishments and one for sand mining. Monitoring of the pilots must reveal the effectiveness of the designs; evaluation of the approach to connect large- and small scales, must indicate its wider applicability
