Sand supplementation on the isle of Texel - The Netherlands

---------------------------------------------------------------------------------------

 

Since 1979 "Rijkswaterstaat" compensates the coast-exit of the 6 million cubic meters of sand yearly with the application of sand from deeper water, the so-called 'sand supplementation'.

 

Sand supplementation is a way to preserve the dunes and by expanding the beach also the dunes are better protected.

The sand is usually won a number of kilometers from the coast; every year between 10 and 14 million cubic meters of sand.

After a big storm it seems that all the raised sand disappeared again.

In other places it carries to the embankment of the beach and the formation of new dunes.

 

On the isle of Texel.

----------------------------

 

Since 1979 already 25 million cubic meters of sand is supplemented on the beaches.

Average a supplementation keeps 5 years, but on the north side of the island they had to sand even more often.

Therefore, in 1995 a 550 meter long breakwater was built which has moved the flow seaward.

Every year Texel loses one-third of the total quantity of sand which washes away from the Netherlands, making it the most expensive piece of coast.
