| Abstract: |
| Based on the forecasting theory of the optimization weighted array, an optimization weighted array model with a runoff response linear model and a time sequential model is developed to predict daily runoff, and the optimal weighting coefficients are derived by the least square method. The predicted results show that the optimization weighted array model improves the forecast accuracy. |
