| Abstract： | This paper introduced two typical flood prediction cases since the hydrological information and flood forecasting system was applied in Danjiangkou water conservancy project. Through the analysis on applicability of the model problem, optimization problem, parameter selection problem, timely human experience factors and comparison of prediction results and measured flood runoff process, this paper summarized the operation strategies, forecast precision and application effect of this system in flood forecast of Danjiangkou water conservancy project. Combined with other existing flood forecasting methods in Danjiangkou water conservancy, the correct and appropriate application of the water regime information and flood forecasting system can greatly improve the accuracy of flood forecasting and reduce uncertainty of data from artificial processing, which can be used as a reliable reference tool for flood forecasting of reservoir. |
