One of the process of soil erosion phenomena by natural rainfall is the soil-particle detachment by raindrops. It is well known that the detached soil particle is easily transported by the water flow, so that soil erosion is advanced. This study is the basic analysis of the relationship between rainfall energy as an impulse by falling raindrop and the amount of detached soil. In the first place, we made the simulation analysis based on the data of splashed soil by single raindrop and obtained the following distribution density function of splashed soil : f(X)=C・exp(-BX^A) Then, we determined parameters A and B and relate them with the rainfall energy by the experiment using rainfall simulator. Finally, (SP)_<unit> which is the amount of splashed soil from unit area was calculated using the obtained values of A and B. The resultant (SP)_<unit> was compared with the experimental value.
