In this paper, the influences of slope surface conditions, such as slope length, slope gradient, vegetation cov-erage, micro-topography, are analyzed in the estimation of resistance. The resistance is described by Darcy-Weisbach coefficient and divided into three parts: grain resistance, form resistance and wave resistance. Combing one-dimensional kinematic wave theory with revised Green-Ampt infiltration model, a model of runoff generation has been established. The effectiveness of the model is validated by Lima's experimental data. From the results of numerical simulation, the functions of micro-topography and vegetation coverage are further discussed, and some other valuable conclusions are also obtained. |
