Abstract

Abstract

Jinsha Bay is one of the most important tourist attractions in the Guangdong-Hong Kong-Macao Greater Bay Area and is favored by tourists from all over the world. The XBeach model is used to simulate the nearshore circulation of the Jinsha Bay, and the occurrence of rip current under different simulated wave conditions is studied. The results show that the rip current in the Jinsha Bay is largely affected by wave height and topography. Under the condition of annual mean significant wave height, there is no rip current along the Jinsha Bay. When the incident wave height exceeds a certain threshold, the risk of rip current increases. The intensity and offshore distance of the rip current are positively correlated with the incident wave height. When the wave direction is perpendicular to the coast, it is the best for the generation of rip current. The beach manager of the Jinsha Bay should improve the early warning of the wave condition in order to reduce the harm caused by the rip current. In addition, due to the characteristics of the long headland, the feeder current of the deflection rips generated by the Jinsha Bay comes from the alongshore currents of the headland and the beach. This can be verified by subsequent field observations. The work of this paper also provides some references for the domestic simulation research of rip current using XBeach model.
