In this study, simulated rainfall was conducted above a series of
soil trays with nine different slopes. The specially designed runoff and
sediment collection system was used to partition total splash into four
directional components and interrill sediment transport into wash
and splash components. The results of this study demonstrated that
slope had a significant effect on these components. Specifically, the
downslope splash loss, total splash loss and net downslope splash loss
all increased with slope gradient and then decreased after amaximum
value was reached. Furthermore, the upslope splash loss and lateral
splash loss decreased as the slope steepness increased. A high error in
calculating the net downslope splash loss and total splash loss may
