Abstract
The objective of this study is to understand the process of splash erosion due to impacting of raindrop onto soil. This is investigated experimentally using a high speed CMOS camera. To understand the phenomena qualitatively, the soil model was developed. The model simulates the fine sand where the diameter of soil particle is 0.1mm. A dent was formed by the impact of droplet on the soil. The droplet deformed with the impacting, and formed the film-flow. The suspension of soil particle was caused with the shear force due to the film-flow. The suspended particle was not entrained into film-flow. The suspended particle was initially settled beside the film-flow. Thus, the suspended particle was not wet.
