Based on the analyses on the characteristics of rainfall and forces acting on raindrop,the physically-based expression of bulk ratio of raindrop group for rain flow is deduced.The physically-based model of mean terminal velocity and the model of rainfall flow kinetic energy are developed according to the relationship between the bulk ratio of raindrop group and rainfall intensity.The parameters of the models are obtained from the simulated rainfall experiments.
