After the storm, one has to cover the structure again with sand. However, in case of acute erosion, it is absolutely necessary to verify it there is only acute erosion. Often there is a combination of acute and chronic erosion. But this chronic erosion in the sea causes that the sea in the breakerzone becomes deeper. The beach slope becomes steeper, and the beach itself is no longer stable.
Erosion never starts without a reason.
In many cases the erosion always existed, but was never a problem. However after some buildings have been constructed near to the coast, the coastal erosion became a problem. In fact in this case one should have considered this problem before starting the development. In some cases some activities in the neighbourhood are initiating the erosion. For example sand mining, building structures upstream of the problem site, construction of revetments and beach walls, etc.
