Effect of Surface Density on Amount of Splash Erosion

Raindrop splash is one of the main dynamic of hills lope water erosion,and the amount of splash erosion is controlled by surface soil condition.In this paper,the effect of raindrop diameter and soil density on the amount of splash erosion is studied.The results show that the amount of splash erosion is negatively correlated with soil density and positively correlated with raindrop diameter.The amount of splash erosion decreases with the increase of the distance from splash cup,and follows exponential distribution.The amount of splash erosion is affected by raindrop diameter and soil density,the relationship of which can be described by the function Ms=0.029 d3.764·ρ5.128.
