When the North Sea waves strike the coast, they remove the sand causing coastal erosion. That is why the government is nourishing at Vejlby Beach. A ship pumps sand from the bottom of the sea and sprays it all over the beach through a pipe. In some places the beach will rise two to three meters from the starting point, and the amount of sand corresponds to the amount of sand in 85.000 trucks. In a few years the process must be repeated when the waves once again have pulled the sand back in to the ocean.
