The idea behind BeachRock is that certain enhanced natural attributes are being used to defend vulnerable coastlines against the growing threat of climate change. The continuous movement of water and wind erodes coastlines around the world threatening people living close to the sea.

To defend these coastlines different methods can be used. One of these methods is the ‘Sand Motor’, a man-made stretch of beach with millions of cubic meters sand. The natural movement of waves helps eroding the Sand Motor and deposits sand further north on the Dutch coast where it is needed to prevent further coastal decline.
