摘要
本文通过室内实验与数值分析探讨了坡面降雨漫流过程中有效糙率的影响，并提出通过优选确定其量值的途径，为野外定量地模拟和预测这一参数打下了基础．
Effective roughness is a sensitive parameter in rainfall-overland flow modeling.It differs from roughness in river flow. Based on experiments in laboratory and numerical analysis,the influence of effective roughness in rainfall-overland flow processes is studied.The method for determining the value of this parameter by optimization is presented in this paper,which may be used in field modeling and forecasting.
