| Abstract: | The GM（1,N） model was developed by the grey relation analysis on the impact factors of measured annual runoff series.Then the BP neural network was applied to fitting the residuals and modifying the predictive values in order to build the grey BP neural network prediction model which was based on the GM（1,N） model.The results of the application example showed that the model could improve the simulation precision of annual runoff. |
