In order to clarify the influence of slope on different wave statistical characteristics,we simulate the wave propagation with different slopes by numerical model,analyze the nonlinear parameters and wave height distribution,and compare the propagation characteristics of waves under different slopes.The results show that under the same condition,wave height will increase with the wave propagation on the slope when the water depth becomes shallow gradually.Slope has a great influence on the wave height distribution.When the slope is steep,the wave height distribution is close to the Rayleigh distribution with the wave propagation to the shallow water.When the slope becomes gentle gradually,the probability of the same wave height decreases.However,the Ursell number does not change significantly with the change of slope.
