摘要
基于栅格型DEM数据,提取数字水系和空间拓扑信息,在考虑流域水保措施的情况下,建立了水文学水力学相耦合的适用于黄土干旱区小流域的分布式水文模型。以黄河无定河水系岔巴沟流域为例,应用分布式水文模型对该流域1970年~1989年11场洪水进行了流量过程模拟。结果表明：计算结果与实测值基本吻合,一定程度证实了所研制水文模型结构、参数和计算方法的合理性。
The digital stream network and spatial information were extracted from raster-based DEM data. The gridbased hydrological and hydraulic model was developed on the basis of excess infiltration mechanism, considering the impact of structural measures for soil conservation on runoff routing. The model was implemented in the Chabagou watershed of the Wuding River that is a tributary of the Yellow River. The computational results, using hydrological data from 1970 to 1989, show that the developed distributed model is suitable for the small watershed in the loess area.
