**4. Conclusions**

Rainfall produced by dripper-type rainfall simulator has been charcterized using piezoelectric transducers. The rainfall drop size distribution and kinetic energy has been measured in 10 second time interval. The rainfall micro-structure has been eveluated by the changes in the drop size distribution at each rainfall intensity. The soil splash erosion has been evaluated using splash cup method under five rainfall intensities ranges between 10 to 30 mm h-1. The rainfall kinetic energy was found to increase with the increase in large drops content (drops with diameter > 2.5). The splash soil loss was correlated with the large drop percentage which emphasize that the splash erosion is highly affected by the rainfall microstructure.
