Abstract:
Simulations of rain kinetic impacts on a watershed are important for agronomic, environmental and regional planning. The goal of this work was to use rainfall data and properties such as rainfall density, rainfall direction and slope, topographic aspects such as slope and slope orientation, to simulate the rainfall kinetic energy on the slopes and the attenuating effect of the vegetation cover reduction of these kinetic impacts. Rainfall data measured at the UFG weather station, along with vector rainfall data collected during 2012 and 2013, were used to simulate the effects on the off season and crop, using the land use classes in the Ribeirão watershed. Paradise. The results showed that the 163 cm² PVC rain gauge is compatible with the standard INMET rain gauge, whose data were used for the present study. Analysis of the results showed that most rainfall comes from the southeast, followed by rainfall from the south. The slope and orientation of the slopes within the basin favored the simulation in order to highlight these impacts. The highest rainfall was in February 2012 (244.3 mm) and January 2013 (252.6 mm), the greatest mitigation of impacts occurred during April 2012 and January 2013, mainly on the opposite direction. predominant rainfall and with a slope that is close to the slope of the rains. It was also observed that the attenuating effect of soil cover showed marked results in relation to cover and growing season and this leads to the conclusion that the simulation adopted reached relevant results since it was possible to show where the largest reductions occur.
