Splash detachment and transport of soil particles by raindrops are the initiating mechanisms of soil erosion by water. The size distribution of splashed particles is very important and effective in the rate of other erosion processes. However, this important issue has been less considered. Therefore, the present study investigated individual and interaction effects of slope, rainfall intensity and spatial variations along the plot and upward and downward splash cup. In addition, the variables were grouped by Tukey test in RStudio software. The tow-way ANOVA in upward splash cup showed that the rainfall intensities significantly affected all variables except particles of < 2 micron and skewness of sediment. A variable except D10, sorting and kurtosis of sediment in downward splash cup significantly differed in varying rainfall intensities and slopes and their interaction. Besides that, the Tukey test explained that the rainfall intensity of 90 mm h-1 significantly influenced study variables compared to those reported for rainfall intensities of 30 and 60 mm h-1.
