Abstract :
The convention method of testing breakwaters in flume by physical model was replaced by purely numerical model. A Bretschneider/Mitsuyasu spectrum wave was generated in numerical flume, and the design of breakwater is in accordance with Code of Hydrology for Sea Harbour, China ("the Code"). Modified Boussinesq type wave equations were solved including a wave reflection term. By purely simulation method, we have a reflection coefficient of 0.45, and in comparison with the Code, it is concluded numerical models can be used in the pre-design of a breakwater, and safety coefficient is used in the Code.
