The rear wall 3 is higher than the front wall and may be provided at its upper portion with a curved section 6 turned towards the open sea and adapted to serve as a deflector. In the embodiments described the principle is applied to a vertical causeway, a sloping causeway, a stone facing for protecting a bank, a breakwater supported on piling and a floating breakwater.</p> |
