The mixed Eulerian-Lagrangian method was used to calculate the wave propagation problem. The velocity and the normal velocity of the boundary of the flow field were solved by the 0 1 mixed boundary element method. The wave process was estimated by integrating the time course of the boundary condition with nonlinear wave And damping layer numerical wave cancellation technology is applied to the far-end radiation boundary to eliminate the reflection of the far-end boundary on the wave.The numerical results give the form of the wave propagation and compare with the linear wave
