| The run-up and the evolution of solitary waves on steep beaches are investigated by using a two-dimensional boundary integral equation model. The model is first used to compute the run-up heights of solitary waves on a relatively mind slope. The model is verified by comparing the computed numerical solutions with available experimental data, other numerical solutions and approximated analytical solutions. The agreement between the present numerical solutions and the other data is found to be excellent. The model is then applied to the calculation of run-up heights on very steep slopes. As far as the maximum run-up of solitary waves is concerned, the boundary integral equation model provides reasonable and reliable solutions. Finally, the evolution on steep beaches is also examined and the obtained wave heights are compared with those calculated from the Green's law. |
