【 摘 要 】

A nonlinear model of wave transformation due to a submerged breakwater is developed on the basis of the nonlinear mild-slope equations. Numerical computation shows that significant amount of wave energy can be transferred from the fundamental component to higher harmonics by adjusting configuration of the submerged breakwater. In case of oblique incidence, wave direction as well as wave period changes due to the breakwater. These results implies the possibility to control wave period and direction as well as wave height.
