【Abstract】 There are different forms of the beds on the natural sandy coast, on which the propagation process of the wave is a typical nonlinear one. Based on this, the nonlinear propagation process of the wave on the small_amplitude uneven sloping bed is analyzed by using the perturbation method.The results of the analytic expression are compared with the correlative experimental data, which shows that the practical situation can be reflected in the evolution of the estabilished model of the wave.更多还原
