Start coastal maintenance Daman

Rijkswaterstaat start 16 March, coastal maintenance in Daman. Between Huisduinen and Dark dunes is a deep trench surface partially filled up with sand for the coast. This reinforces the coast of Den Helder and the head of North Holland in the coming years well protected from the sea.

By the sea currents occur naturally deep trenches in the seabed. For the coast of Den Helder is such a deep trench, moving slowly toward land. This can weaken the coast. To avoid weakening, Rijkswaterstaat fills the trench with 3,5 million cubic meters of sand from the North Sea. The sandy shore is strengthened and continues the shoreline in place.

Activities
Sun 10 kilometers offshore dredger sucks itself full of sand from the seabed. By means of a suction head and pipe comes to the sand, mixed with seawater, in the hold of the ship. The vessel then fills the trench to collapse the coast through sand. The activities last until late April.

Maintenance Dutch coast
The sand near shore, on the beach and in the dunes protect our country against the sea. By flow, wind and waves and rising sea levels we hit the sand, and thus land, However constantly lost to the sea. If nothing happens, Slowly slide the coastline inland by. Rijkswaterstaat is working with the water authorities continue to maintain the Dutch coast. To keep the coast in top condition, Rijkswaterstaat used average 12 million cubic meters of sand per year.

continued need
More than half of the Netherlands lies below sea level and is therefore vulnerable to flooding. live in these areas and work of millions of Dutch. Work to protect against flooding and storm surges is therefore a continuing need in Netherlands.
