文摘
- •
With the use of a disdrometer, the kinetic energy of the rainfall was measured.
- •
An estimation of energy based on rainfall intensity is proposed for Southern Brazil.
- •
The rainfall magnitude and season has small effect in the kinetic energy estimation.
- •
The kinetic energy contributes to explain the hydrological variables in the catchment.
