( 2 ) the results of the rainfall - affected runoff scouring experiments in lab . when the rainfall intensity was less than l . omm / min , the soil erosion caused by the combination of rainfall and the upslope runoff was more than that caused by only the simulated rainfall . when the rainfall intensity was more than 2 . 0mm / min , the upslope runoff strengthened the effect of the runoff yielded in the local area on the dyke slope surface , and the effect increased with an increase of rainfall intensity
2 、室内模拟降雨+放水冲刷试验结果雨强小(如i 1 . 0mm min )时，上游注入水量对戗坡侵蚀作用比降雨在戗坡上所产生径流的侵蚀大；雨强大时( i 2 . 0mm min ) ，上游水量下泄与当地降雨径流一起增强对戗坡面的侵蚀作用，雨强越大，侵蚀作用也越大。
