摘要
坡面流的时空变化过程对坡地上土壤侵蚀机理的研究及水土保持工作都具有十分重要的意义.本文将运动波汇流理论应用于黄土区小流域的坡面流计算,着重阐述了坡面流的运动波方程基本原理和相应的数值计算方法;并用黄河水利委员会绥德水保站桥沟流域1号和2号小区天然降雨径流过程资料进行了模拟.模拟与实测径流过程吻合程度良好.
The time and space variation of runoff flooding on sloping land is of great importance for the study of the mechanism of soil erosion of sloping land and soil-water conservation.In this paper, the Horlton infiltration curve is used to calculate the flow process,the kinematic wave theory and finite-difference method are used to simulate runoff flooding on sloping land.The method has been tested using observation data of the Qiaogou watershed.The simulation results are satisfactory.
