The effect of rainfall intensities and slope gradients on the characteristics of infiltration,runoff and sediment yield was investigated by rainfall simulation experiment of red soil.The results show that,the runoff occurring times were shortening with the increasing of rainfall intensities and slope gradients.For the red soil with poor permeability,runoff intensity was lower as slopes were steeper,while it increased with increasing rainfall intensity,and it was slope accepting rainfall dependent.With the i...
