Abstract
The flow of an incompressible inviscid fluid with surface tension (Bond number is closed to 1/3) on the uneven bottom is studied. The effects of different cases of flow on the nonlinear surface waves were analyzed. The numerical simulation for the fifth-order equation was made by pseudo-spectral method, and the waterfall plot of the wave was draw with software. The results show that the fifth-order dispersive item did not change the developing tendency of the surface wave, only affected the number and position of the solitary wave, however, when the flow condition was changed, there appeared greatly variation on the surface wave due to fifth-order dispersive item.
