Abstract: Abstract:SWAN, a wind wave model, has been modified to take into account wave refraction-diffraction effects from the extended mild-slope equation when wind waves pass through a extremely uneven sea bottom in the presence of current. In our modified model, the diffraction correction parameter introducedby Holthuijsen et al. [10] has been adjusted to better predict the combined effect of the higher-order bottom effect, wave-bottom interaction and wave-current interaction. After a preliminary analysis, the influence of the correction parameter is discussed, and a comparison is made between the original and the new phase-decoupled versions of SWAN through some typical examples of wave fields around semiinfinite breakwaters, breakwaters with gap, and detached breakwaters on different bathymetries. The results show that the new phase-decoupled model exhibits improvements in both numerical convergence and Prediction results for the case of a steep varying an extremely uneven sea bottom than the original one.
