Everything else may go but that wall is here to stay. Beaches with hard structures can return, though it takes longer, and rocks and concrete in the wave zone also make for a dangerous combination. It shows how different combinations of coastal defences and wave and tide conditions affect overtopping and flood risk. And as I said in my first comment that is because of the road.
