In this paper, the hydrodynamic survey data around Fenghuang Island in March 2018 and April 2022 were collected to analyze the impact of the demolition of Fenghuang 2 Island on the hydrodynamic of Sanya Bay. The results show that the tidal pattern of the Sanya Bay is irregular diurnal. The current velocity outside the mouth of the Sanya River is slightly lower than that in Hanoi. The mean current velocity near the shore gradually increases to the open sea, and the mean current velocity in Hanoi and the mouth is significantly lower than that in other sea areas. Before the demolition of Fenghuang II Island, due to the weakening of the shield effect of Fenghuang II Island on the southbound waves, the northwest coastal sand transport capacity was enhanced, resulting in the change of the sand content of the surrounding stations of Fenghuang II Island.
