Based on consideration of the actual terrain and soil physical properties,we developed a numerical calculation model by using kinematic wave theory and the hypothetical channel network for simulating the process of "Rainfall-Runoff" of a distributed-type basin.

本研究以黄土高原北部的六道沟流域为流域模型,在确定试验流域地形和土壤物理性质的基础上,利用运动波理论和拟河道网开发分布型流域的"降雨-径流"过程的数值计算方法,对观测流量数值模拟结果的分析表明,该计算方法适用于北部黄土高原的实际,研究结论为该区域的地表水资源的推求提供了一种有效的数值计算方法。
