An efficient finite difference scheme for solving the extended Boussinesq equations as derived by Nwogu (1993) is proposed. The alternate direction iterative method combined with an efficient predictor-corrector scheme are adopted for the numerical solutions of the governing differential equations. The proposed numerical scheme is verified by three test cases where experimental data are available for comparison. The first case is wave focusing by bottom topography. The second case is wave diffraction around a single breakwater. The third case is wave diffraction over a shoal. Numerical results agree very well with the corresponding experimental data in the cases.
