Preliminary study on mechanics-based rainfall kinetic energy

摘要: A raindrop impact power observation system was employed to observe the real-time during a rainfall event and analyze corresponding characteristics. The experiments were conducted at different simulated intensities. As intensity increased, observed increased linearly indicating would be satisfactory for characterizing erosivity. Momentum is product of mass velocity (Momentum=MV), which related value. Since there no significant difference between momentum power, can represent relationship provides convenient way calculate kinetic energy. value energy based on higher than classic showed linear correlation, indicates that characterize article establishes preliminary by using momentum, providing foundation replacing traditional methods estimating rainstorms.
