摘要

中文摘要: 基于栅格型DEM数据，提取数字水系和空间拓扑信息，构建由水文模块和泥沙模块两部分组成的黄土高原多沙粗沙区小流域分布式水沙耦合模型。以黄河无定河水系岔巴沟流域为例，应用所建立的模型对该流域1970年～1989年11场洪水进行流量沙量过程模拟。其中10场洪水模拟的确定性系数在0.7以上，11场洪水的含沙量模拟相对误差都在15％以下。结果表明，模型具有一定的计算精度，一定程度证实了所研发模型的结构、参数和计算方法的合理性。

Abstract

Abstract:The digital stream network and spatial information were extracted from raster based DEM data. The grid based hydrological and silty 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 for 11 floods from 1970 to 1989 in the Chabagou watershed of the Wuding River that is a tributary of the Yellow River. The “Nash%” of 10 floods were beyond 0.7 and all the relative errors of the simulated silt content were under 15%. The results show that the developed distributed model is suitable for the small watershed in the loess area.
