| Abstract: | Based on the four random variables in physics,namely ,the inital projecting speed,angle,deviation and water drop diameter,a mathematic model of water drops random spattering is set up;and by using Runge-Kutta and Monte-Carlo Methods, the rainfall intensity on earth in deflecting flood release and atomization is calculated. This model has been rerified and applied to a certain hydropower station to predict the distribution of rainfall intensity in the deflecting flood release and atomization. |
