A new approach to numerical simulation of nonlinear wave propagation and its experimental verification

  • Anumerical model is developed with a new type of Boussinesq equations employed as the governing equations.In the present numerical model,the seven-point finite difference scheme is used to discretize the spatial derivatives,the fifth-order Runge-Kutta-England scheme is employed to perform the time integration,and the appropriate out flow boundary condition is adopted.Systematic numerical modeling of wave propagation is performed with a uniform depth from shallow to deep water and from linear to nonlinear waves.The calculations show that the results of the present numerical model are basically agreement with those of analytical solutions.An experiment is carried out for wave propagation over a submerged bar with different incident wave parameters.The comparisons between the numerical resolutions and the experimental data are made.
