Stability of Multi-Layer Berm Breakwaters abstract

The front slope stability of the berm breakwater was studied with two dimensional model tests. The berm recession of a reshaping berm breakwater plays a very important role for the stability of this kind ofstructure. This paper deals with the investigations of the reshaping of a multi-layer cross section(Icelandic type). Tests have been carried out in two cases. The first case is the typical form of the multilayer berm breakwater and the second case is a new idea for this kind of structure by using one order smaller stone mass in front of the berm. A comparison is made between the berm recessions for the different cases. It can be concluded that in the second test case, the total costs of the project can be reduced without decreasing the stability.
