The construction of Cao'e River sluice has a significant impact on the drainage of Shaoxing river network. Different gate opening times have different degrees of impact on the decline of water level and elevation and the change rate of flow velocity in a certain period of time. In order to find out the optimal opening time to ensure that the Changshui River network has the least impact on the lives of local residents when the flood comes, this paper establishes a two-dimensional hydrodynamic model of the river network and analyzes the overall change of Changshui River during the opening of the sluice. Through simulation calculation, the relevant data of the river 72 hours after the opening of the gate are obtained and analyzed. According to the given water level increase rate and time change, when the rainstorm is coming, the Cao'e River gate needs to be opened 9 hours ago, and the drainage function of Changshui River can be optimized.
