Abstract:There are many tributaries in the middle Yangtze River,and the water system is complex.As the result of water storage of the Three Gorges,water and sand conditions under the dam have changed violently.These factors cause the difficult of water level prediction.Based on the measured data of the middle Yangtze River,we consider the tributary remittance and new water and sand conditions,and put forward the correlational analysis method and multiple regression method to forecast the river water lever of upper and lower Jingjiang reach,Chenlingji-Hankou,Hankou-Hukou reach.The method is examined by the measured data,and the absolute error is less than 0.4 m.The method can improve the water lever prediction accuracy of the middle Yangtze River.
