Abstract	Ice disasters occurred frequently in Ningxia—Inner Mongolia reach, and safety of the Yellow River, people’s lives and property security are seriously threatened. In this paper ice control condition in the Upper Yellow River is introduced for the first time to clarify the relationship between flow routing and ice control security. Based on the feature of flow routing during ice control period, the improved method for different reaches and periods is proposed in this paper. Three sections in the Ningxia—Inner Mongolia reach of the Upper Yellow River are selected as research objects. The 10-day flow data of sections over the past 20 years are used for parameter calibration, training and verification. To investigate the method performance, we applied a number of criteria factors (Relative Error, Root Mean Square Error, Mean Absolute Error, and Correlation Coefficient) and two methods, conventional method and improved one. The results demonstrate that the improved method which considers ice impact factors such as data on freeze-up and break-up, channel storage increment, temperature, has consistently superior performance in comparison with the conventional method. The accuracy and superiority of the improved method are verified by comparative methods.
