Abstract: Physical models are not able to fully characterize changes in boundary conditions of sedimentation patterns in reservoirs across rivers with high sand content. To address this issue, a one-dimensional mathematical model of water flow and sediment transport in the Haibowan Reservoir was constructed based on the basic equations for turbid open-channel flows, the mass balance equation for suspended sediment transport, and the measured data of the Haibowan Reservoir on the Yellow River. Finally, the model was validated using the measured data of the Haibowan Reservoir in 2019. According to the long-term simulation of the flow rate, sand content and thalweg, high simulation accuracy was observed. This indicates that the model can provide a scientific basis and technical support for formulating sediment discharge plans and making management decisions for the Haibowan Reservoir in future.
