A numerical method to solve the second-order interaction between a multi-component random wave and a submerged obstacle is presented by using Stokes' wave expansion and Green's second identity. The wave is unidirectional random wave, but nonlinear interaction up to the second-order is strictly considered. Laboratory experiments with several multicomponent random waves for several different wave powers are conducted. The transmitted wave spectra obtained both in the experiment and in the numerical calculation are compared. The effects of wave breaking on the obstacle to the transmitted wave spectra are also investigated.
