Abstract: Three-dimensional evolution of nonlinear long waves after interacting with a straight thin breakwater is investigated in this paper. The primary interest is to apply a weakly nonlinear and weakly dispersive theory with taking into account the effects of steady currents to predict the reflection, scattering and diffraction of solitary waves by a breakwater. For solving this strong interaction problem, the wave- current two-equation model is developed to calculate the velocity potential of the flow field and the free- surface elevation.
