Abstract

Based on the Boussinesq type equations with the second order nonlinearity and dispersion,an improved Crank-Nicolson method is employed to simulate the evolved wave propagation passing over the submerged bar.Comparisons are made between the experiment data and the numerical results,which clearly demonstrate the fact that higher-order Boussinesq type equations perform well in accurate prediction of the evolved wave fields than classic Boussinesq equations and the extended Boussinesq equations~([4]) in the uneven bottom and strong nonlinearity and dispersion.At the same time,the higher-order Boussinesq equations used in this paper is validated by experimental results,which proves that the present equations can be used to solve the practical coastal engineering problems.
