Abstract
A new version of the Stimulating Wave Nearshore (SWAN) model (version 40.51) was used to stimulate the evolution of directional irregular wave near a single breakwater and the Wen spectrum was adopted as an input spectrum. The wave diffraction effect of irregular wave, which is the main improvement compared with the previous SWAN versions, was tested with the experimental data of single breakwater collected in the State Key Laboratory of Coastal and Offshore Engineering (SLCOE) at Dalian University of Technology (DUT) and the stimulated results of Wu Yan and JONSWAP spectrum as input data, respectively. By comparing the results in four cases, it is seen that the results stimulated by the SWAN model with the JONSWAP or Wen spectra are better than those with Wu’s spectrum, and the results simulated with the Wen spectrum is little larger than those with the JONSWAP spectrum and more closely approximated to the measured data compared to the results with the JONSWAP spectrum. It is then concluded that the new SWAN model with the Wen spectrum can be well used to stimulate wave diffraction around a single breakwater.
