民堤-
( 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 、室內模擬降雨+放水沖刷試驗結果雨強小（如i 1 . 0mm min ）時，上游注入水量對戧坡侵蝕作用比降雨在戧坡上所產生徑流的侵蝕大；雨強大時（ i 2 . 0mm min ） ，上游水量下泄與當地降雨徑流一起增強對戧坡面的侵蝕作用，雨強越大，侵蝕作用也越大。
