The relationships between VIC model parameters and climate and soil factors as well as the regional distribution pattern are analyzed. The multi-regression analysis approach is used to establish formulas that can calculate model parameters of ungauged basins. Application results show that the VIC model performs well in the Ankang, Baohe and Lanhe ungauged basins, the model efficiency reaches 91.41%, 90.01% and 86.55% respectively, which are similar to the results estimated by the calibrated parameters. It is shown that the proposed method can be used to modeling runoff in ungauged basins.
