Abstract: A river ice model for the reach of Yellow River from Sanhuhekou to Wanjiazhai is presented. This model mainly consists of three coupled parts. They are hydraulics model, thermal model, and ice model. The model was first validated with the measured data from Toudaoguai Hydrological station upstream of the Wanjiazhai Reservoir, since Toudaoguai is an important control section of the Yellow River for flood control, ice flood control, and water regulation. Using the validated model, the influence of Wanjiazhai Reservoir’s operation on the discharge capacity of Toudaoguai Section was investigated. Through the analysis of Wanjiazhai Reservoir in five different flow conditions, the critical water level value of Wanjiazhai Reservoir was proposed. If this critical water level is exceeded, the flow at the Toudaoguai would be affected. The mechanism of this influence was also analyzed.
