洋河流域非线性产汇流实时预报模型研究

Research on Realtime Flood Forecast Model of Nonlinear Runoff and Concentration for Yanghe Basin

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,建立流域非线性产流、汇流模型以及流域洪水实时预报校正方法,该方法应用于洋河水库流域洪水预报,取得较为满意的效果。

The effects of basin nonlinear runoff and concentration are considered from the basin rainfall spacetime changes and the basin topography as well as the river channel characteristics.This paper presents the basin models of nonlinear runoff and concentration and the method of realtime flood forcast.Using them to forecast the floods of Yonghe reservoir, it shows that the models and method are effective in practice.
