Regarding the impact of the construction of the Guotan Hub of the Tanghe Navigation Project on the flood control safety of the river channel, the design flood of Guotan Hub was calculated through measured flood data of hydrological stations and linear interpolation method. According to the measured cross sections and thalwegs over the years, the river channel scouring and silting evolution and evolution trend prediction were analyzed. The water surface profile of a river was calculated using the energy equation of a constant non-uniform gradient flow equation. The second-order RungeKutta method of a two-dimensional model was used to simulate the impact of construction projects on the flow field during river flood discharge. The results indicate that the Guotan Hub of the Tanghe Navigation Project has a relatively small impact on river flooding so that solved the technical problem of flood impact assessment for Guotan Shipping Hub, which provided reference for relevant departments.
