VSCM模型在汤河西支流域河道洪水演算中的应用

Application of VSCM model in flood routing in the west branch watershed of Tang River

本文采用VSCM模型(变动态存储系数模型)进行汤河西支流域河道洪水演算,并结合实测水文数据,分析动态存储系数模型在汤河西支流域河道洪水演算的适用性。研究成果表明:VSCM模型可考虑河道地形对洪水演进的影响,洪水模拟精度符合水文预报规范精度要求,可用于研究流域洪水演算。研究成果对于汤河西支流域防洪具有参考价值。

This paper conducted the channel flood routing in the west branch watershed of Tang River based on VSCM model,and the applicability of the model was evaluated combining with the measured hydrological data. The results show that VSCM does consider the effect of river topography on flood routing, and its flood simulation accuracy meets the requirements of ＂Forecasting norm for hydrology intelligence＂ , so that VSCM can be used to study flood routing,which can also provide reference value for the flood control in the west branch watershed of Tang River.
