根据在黄土塬坡上进行的野外大型人工降雨径流产沙试验的观测资料,分析并建立了坡面上雨滴击溅产沙模型。给出了实际降雨过程的雨滴动能计算的理论公式。给出了考虑击溅产沙能力受坡面漫流或其它覆盖物影响下的击溅产沙过程的模拟结果。通过对试验现象和结果的结合,描述了雨滴动能对坡面水流及坡面土壤的作用。
Based on the observation data of large-scale artificial runoff and sediment yield test conducted in the Loess Plateau, the model of raindrop splashing and sediment production on the slope was established and established. The theoretical formula for calculating the kinetic energy of raindrops is given. The simulation results of the spattering and sediment production process under the influence of the surface runoff or other coverings considering the ability of spattering and sediment production are given. Through the combination of test phenomena and results, the effect of kinetic energy of raindrops on water flow and slope soil is described.
