Application of rainfall-runoff forecast method in Liangjiang hydropower station

Through analysis of runoff mode of Liangjiang hydropower station, the analysis result shows that the river basin is located in the humid and semi-humid area with the abundant rainfall, the total rainfall runoff amount is mainly depend on the antecedent soil moisture and the rainfall amount, the runoff mode of the area is belong to the runoff yields under saturated storage, therefore, the rainfall-runoff forecast method is suitable in the area. And then the paper elaborates the calculation method of the rainfall-runoff factors and the determination of the rainfall-runoff correlation diagram, and introduces the specific steps of rainfall-runoff forecast
