An annual runoff forecasting method is presented based on unit root test, cointegration test and error correction model of the upper and lower reaches of the Second Songhua River. The method of cointegration analysis is applied to the annual runoff data of the Baishan and Fengman hydrology Stations; then the error correction model is set up, which can predict the annual runoff of Fengman hydrology...
