摘要
VIC模型作为具有物理基础的大尺度水文模型得到了广泛应用,然而其现行汇流方案无法用于场次洪水的模拟。本文采用单位线法和Maskingum-Cunge法对模型的汇流方案进行了改进。以时段气象数据驱动VIC模型进行产流计算,以所改进的汇流方案进行汇流演算,对西江南宁以上流域的场次洪水过程进行了模拟,结果表明,改进的汇流方案可以较好的模拟出口断面的洪水过程,并对洪水的空间演进过程具有一定的描述能力。
As a macro-scale distributed hydrological model with physical basis, the variable infiltration capacity （VIC） model has been extensively applied. However, the current routing scheme doesn＇t have the ability to describe the sub-daily flood. In this pa- per, the unit hydrograph and Maskingum-Cunge algorithm were used to improve the routing scheme. As an example, the VIC model with improved routing scheme which was driven by 3-hour meteorology data has been used in Xijiang basin （above Nanning station）. The results show that the improved model can simulate the process of sub-daily flood well and describe the spatial move- ment process of the runoff to a certain extent.
