The Dutch Context

City of Egmond

• Shortage of natural sediment

• Consequence: Structural erosion

• Solution: Nourishments

• Sea level rise

• Traditional nourishments since 1970’s • Shoreface nourishments since 1990’s • Now experimenting with the Sand Engine!

Nourishment strategies for maintenance

• Scale (Time and Space)

• Shape: dynamic instead of equilibrium

• Multi-purpose solution (coastal safety+ )

• Multiple fathers and mothers

The Sand Motor: a unique solution

International opportunities?

International case studies

• Start point is local context (reference situation) • Match of scales? • Dynamic objectives? • Does sand fit the culture? • What is the alternative?

• Not for copy paste

• Take the approach: Building with Nature

• Plenty worldwide opportunities

• Joint responsibility to make it happen…

…. with critical role to engineering consultants
