CADMAS-SURF is one of the accurate numerical models that can apply to a performance-based design of maritime structure. However, there were a few application examples to irregular waves, because of the increase of computation time. Thus, a systematic study of irregular waves by CADMAS-SURF has been conducted with a cooperation of research group. The numerical simulations are conducted for transformation of irregular waves propagating a flat flume with a constant depth. The calculated spectra and representative waves are compared with those set as the target and the results of theoretical study. The characteristics of irregular waves generated by CADMAS-SURF are consistent with the existing knowledge. The modification of given spectra to make irregular waves is recommended to agree the spectra, significant wave height or significant wave period with the target at some point. The adequate selection of option parameter is required to avoid the numerical damping.
