Shoreline sand wave movement is one of the hot issues in coastal dynamics research. The nonlinear nearshore waves constitute the core driving force for shoreline sediment transport, significantly enhancing the lateral sediment transport intensity and exerting an important influence on shoreline sand wave movement. By using the XBeach model, the evolution process of the profile of a typical sandy beach in Haizhou Bay under the action of nonlinear waves was simulated, and the comprehensive influence of wave nonlinearity on the lateral sediment transport and sand wave movement of the beach was analyzed. The results show that the nonlinearity of waves has a relatively significant impact on the sediment transport along the shoreline of Haizhou Bay. The sediment transport in the breakwave zone 500 meters offshore is frequent. The peak line of the sand wave moves towards the shore year by year, and the peak elevation increases year by year. Within the calculation range of the model, the net sediment transport to the sea shows a slightly eroded feature in the intertidal zone of the nearshore tidal flat of Haizhou Bay. The research results have important reference significance for grasping the erosion and topographic evolution laws of the nearshore beaches of Haizhou Bay.
