| Abstract: | The main factors affecting the ice-jam flood and the principle of reservoir operation for minimizing the ice-jam disaster by means of discharge regulation are described. Empirical formulae for calculating the flow under the stable or unstable ice cover are established. Based on the hydraulics for ice, the law of ice flows and the basic equations for ice-water two-phase flow, a mathematical model of reservoir dispatch for ice-jam flood control is proposed. The validity of the model is verified by case study of Yellow River. |
