To improve the mooring condition of Phase Ⅳ & Ⅴterminals of Rizhao port ，we employ MIKE21 BW model to study the wave phenomena,in which four layout schemes and three structural wharves are considered.In the simulation，reflection coefficients of wharf structures are obtained from physical model test of the wave profile.The study shows that using pile gravity type complex wharf and moving PhaseⅤterminal further south which is allowed can improve the wave height distribution and the berthing condition.
