Meet the Sand Motor in the Netherlands, construction, operation and research (Sand Engine)
Just a few notes.
In 2011. night and day for 4 months 21.5 cubic meters of sand was dredged and deposited along the Dutch coast covering an area of 300 acres. Picture 256 football fields. At one point 2km wide and protruding 1km into the North Sea.
Building with nature.
Influences of wind, waves and currents all being tracked. Coastal currents have been changed. Over 20 years it is estimated 35 hectares (80 acres) will be added by nature itself, reinforcing the coastline for the the period.
The Netherlands (Holland) province of South Holland will gain a lovely recreation and wildlife area.
A fine Dutch effort working with nature, no doubt.

21 Feb 2013: Report
To Control Floods, The Dutch Turn to Nature for Inspiration
The Netherlands’ system of dikes and sea gates has long been the best in the world. But as the country confronts the challenges of climate change, it is increasingly relying on techniques that mimic natural systems and harness nature’s power to hold back the sea.
by cheryl katz
On a freezing winter day along the south-central coast of Holland, two beachcombers, hunched against the wind, stroll along a crescent of sand extending more than half a mile into the North Sea. Nearby, a snowkiter skims over the 28 million-cubic-yard heap of dredged sediment spreading along the shore. If all goes as planned, the mound will eventually disappear, rearranged by ocean currents into a 12-mile-long buffer protecting the coastline for the next two decades.
[...]
The new Dutch technology has promise, and flood management agencies in the U.S. are keeping an eye on it, said Jason Needham, a consequence specialist with the U.S. Army Corps of Engineers’ Risk-management Center in Davis, Calif., who recently spent a year in the Netherlands on a staff-exchange program. But sophisticated devices like Smart Dikes are expensive, and haven’t yet proven their worth, he said. As for natural defenses, Needham said the concepts are good, and “everyone agrees our wetlands need to be restored.”
The two countries have different approaches to flood control, Needham acknowledged, with the Dutch focusing mainly on prevention, while Americans emphasize emergency preparedness and recovery. In the face of an uncertain future climate, however, the objectives are now converging. The goal, as Needham puts it, is “how to get people safer without putting a big wall up there.”

Taming the floods, Dutch-style
What Britain can learn from the Netherlands about defending against floods and adapting to climate change

The sea remains as major flood threat to the Netherlands and on the windy coast, not far from the major cities of Rotterdam and the Hague, a €75m government-backed experiment is taking place. A new crescent-shaped peninsula, 4 miles long, has been created just in front of the sandy beach. The idea is that rather than having to replenish the beach every year to protect the coast, the waves and currents will wash the 20m cubic metres of sand used to create the peninsula into place: the project is called the “sand motor”.

peninsula. It extended 1km into the sea and was 2km wide where it joined the shore. Photograph: Courtesy Joop van Houdt/Rijkswaterstaat
