WebSea Walls Sea walls aim to protect the coast by by shielding it with concrete, steel and stone. Some sea walls are recurved, like the one shown in the video of Scarborough sea defences below. The aim of the lip is to deflect the energy of the wave. They are effective in protecting cliffs from erosion and also act as a barrier to prevent flooding.
