Soil erosion is caused by the translation of detached soil toward downslopes. In the case of weak rainfall or at the beginning of rainfall, this phenomenon takes place only by the soil splashes generated by the impact of raindrops striking soil surface. This paper describes the experimental results of radial and angular distribution of soil splashed by a waterdrop impact. As a result of statistical analysis of experimental data, it become clear that radial, angular distributive density function was expressed by the exponential type. Γ type respectively. Exponential type function contains one parameter λ which is expressed only by the diameter of sand particle and the Γ type contains two parameters α, λ. Parameter α is constant and λ is expressed only by the ratio of sand diameter and waterdrop diameter.
