Wide Green Dike

Practical challenge

The Wide green dike (Brede Groene Dijk) is a pilot reinforcement project for the present dike along the Dutch Dollard coast. The pilot is an alternative to heightening and broadening the existing dike with fortified revetment of asphalt and stones to comply with the safety standards. Given the importance of the area for nature, landscape quality and recreation, the Wide dike proposes a thick layer of grass and locally extracted clay on the entire gently slope merging smoothly into the adjacent salt marshes without any drainage ditch. If you’re interested, we invite you to read more about this pilot on the website of the Regional Water Authority.
