Description :
A new approach is proposed to simulate splash erosion on local soil surfaces. Without the effect of wind and other raindrops, the impact of free-falling raindrops was considered as an independent event from the stochastic viewpoint. An empirical linear function combining the kinetic energy and soil shear strength was used to estimate the impacted amount of soil particles by a single raindrop. The total splash amount was seen as the sum of the impact amount by all raindrops in the rainfall event. The comparison of simulated data with measured data showed that this model could be applied to simulate the soil-splash process successfully.
