The objectives of present paper are to develop the powerful numerical method for solving diffraction problem of nonlinear water waves in time-domain and to clarify the interaction of solitary wave and the offshore structures. The improved Orlanski boundary condition, which includes the term of spatial gradient of phase velocity, is proposed and the development of flow is obtained by a time stepping procedure with velocity potential feild at any one instant obtained by a boundary element method. The numerical results obtained by the present method were compared with the experimental data and numerical results by another method, so that the accuracy of the present method was confirmed. The diffraction problems of solitary waves by the bottom-seated structures and the fully submerged circular cylinders were computed, and the characteristics of the wave forces and the scattered waves were discussed.
