This paper optimizes the operation mode of the combined drainage channel box sluice in H river basin of a city in south China to solve the problem of frequent sluice opening.Based on the InfoWorks ICM software, the hydraulic model of drainage system of the river basin was established, the measured rainfall and liquid level were screened, the model parameters were determined by using the rainfall data of medium and heavy rain, and the model was verified by using the rainfall data of heavy rain. The optimal liquid level is obtained by analyzing and comparing the simulation results. The simulation results are basically consistent with the actual precipitation.After optimization, the optimal liquid level of the combined drainage channel box sluice gate increased by 0.8m compared with the manually operated maximum liquid level. After the operation mode of sluice is optimized, the annual sluice opening times are reduced by 78%. After the experience, the InfoWorks ICM hydraulic model has high reliability, and the optimal sluice opening liquid level can be obtained through simulation analysis, which can more effectively prevent waterlogging and reduce river pollution.
