Short crested seas in harbour modelling

In the near future it is planned to construct a short crested wave-maker for use in physical models of harbours. This report is concerned with three aspects of that development. Firstly, it highlights the differences in harbour and vessel response that are expected as a result of generating short crested waves instead of the long crested waves used at present. The second aspect concerns basic design requirements. Finally, it is shown that set-down compensation at the short crested wave-maker is necessary to limit the generation of spurious long waves.
