MIKE21 SW model was used to simulate the wave field in a large sea area, and CGWAVE model was used to calculate the wave field in the small area that near the planned dock, then the wave elements on the both sides of the sea area were extracted and analyzed. The results show that the wave heights in the direction of NW and NNW are much smaller than that of SE and SSE, because of the bay mouth sea waters in the north of planned dock is shallow and the cover effect of the north island chain. The combined application of MIKE21 SW model and CGWAVE model
