Abstract

Lanhe River is a main branch of Hanjiang River,Lanhe River basin is a heavy rain center of Hanjiang River,and the rainfall is uneven.The flood forecast model is designed in accordance with the character of Lanhe River basin.Through the analysis of historical rainfall data,the accuracy of model is calculated and calibrated,and the model is applied in the flood forecast system of hydropower dispatching automation system at Linhekou Hydropower Station.The forecast model adopts three-water-source Xin'anjiang model to realize the function of fixed time forecast,supplementary forecast,estimation forecast and graphic display.The rule of Lanhe River flood is cleared basically through flood forecast system.
