Abstract:: The relationship between flow velocity of sloping face and runoff characteristic was studied under the simulated rainfall in this paper.The results indicated that: when the slope of the fixed long plot ranged from 5°to 20°,the flow velocity was increased along with the slope.Meanwhile,the flow velocity was increased with time at the same slope.The trend of flow velocity can be divided into three phases: the initial stage of runoff from precipitation; the stage of minute form on the slope face; the stage of rills came basically into shape.While the slope gradient was 25°,the demarcation of three stages was unclear.The close relationship between flow velocity of sloping face and runoff characteristic can be illustrated by power function y＝ax^b (0
