| 摘 要： | 考虑到流域降雨时、空变化和流域地形、河道特征对流域产汇流的非线性影响，通过改进时变增益水文模型（TVGM），建立了流域非线性产流、汇流模型以及流域洪水实时预报校正方法，将研制的模型以及流域洪水实时预报校正方法，将研制的模型应用于洋河水库流域洪水预报，取得较为满意的效果。

| Abstract: | The effects of basin nonlinear runoff and flow concentration are considered from the basin rainfall space_time changes and the basin topography as well as the river channel characteristics. The basin models of nonlinear runoff and flow concentration, and the method of real_time flood forcast are presented by means of improving time_variant gain model.Using them to forecast the floods of Yanghe River reservoir ,it is shown that the models and method are effective in practice. |

| Keywords: | nonlinear system runoff flow concentration real_time forecast |
