ESTUDO PRELIMINAR DA VARIAÇÃO DE MICRO-FORMAS E DA COBERTURA VEGETAL NA GERAÇÃO DO RUNOFF E PERDA DE SOLO EM VERTENTE DO MUNiCÍPIO DE GOUVEIA/MG

AbstractThis study intents to analyze with the mechanical work of the rain runoff in the region of Gouveia - EspinhaçoMeridional, State of Minas Gerais, Brazil, under natural conditions and not induced rainfall. It showssignificant differences in the denudation processes taking place on the ground surface, due to the variationof micro-forms and the vegetation cover.The hydro-erosive date for the period between February and September/00 indicate a more acceleratedlowering of the ground surface on the lower slope. In the areas with lower vegetation cover, the runoff flowcuts down the soil surface, deepening the micro-ravines. In other places of the slope where the hydrologicalforces are week and vegetation cover thicker, a higher stability of the micro- topography and a more moderatedeposition of the sediments can be observed.
