Review Problem Owner Perspective
The paper deals with the design and maintenance of berm breakwaters and focusses on the longshore transport in a monsoon-hurricane wave climate. The main object is to determine the initial nourishment needed to survive the design life of 50 years. Three probabilistic approaches are applied to the problem. In the user’s perspective we do not necessarily focus on the correctness of the approach but on the appropriateness of the approach for the problem on hand. The user in this respect is the designer of a berm breakwater which has to guarantee a 50 year life and which has little means to get information during the life of the berm breakwater other than at its failure. This aspect is essential to understand the reasons behind the focus on the uncertainty in the long shore transport.
