ON OPTIMUM BREAKWATER DESIGN

J. van de Kreeke, A. Paape

Abstract


A breakwater design is optimum when it results in a structure that meets the requirements at minimum total cost. The total cost consist of cost of construction, anticipated damage and economic loss due to failure of the structure. For any type of structure the design wave or load is governed by the condition of minimum total cost. This is worked out for some possible designs for Europoort Harbour, Rotterdam. The data needed are often insufficient, however, for reasonable assumptions important directives can be obtained especially with respect to ranking of structures of the same type.
