Resumo
The: evaluation of the processes tried to make connections
with different pluvíophase (duration and intensity of the precipitations with the quantity of material arising from the slopes (soil and 1vater), as to the form, declivity and topology of the vegetal covering or use and handling of the soil. The outcome of the analysis carried out were obtained through directed sample areas in a period of a meteorological sucessions. Thus, after to set up the choice of the special indícating and temporal and observations station was implanted for the morphodynamics processes, represented by nine detached parts that composed three covering groups (wood, planting and pasturage) and different slopes. The field contral was achieved througt daily observations of pluvioerosive effects. After quantitative evaluation, of erosive loss, the material was analysed and showed (granulemetric-structural to the ground dragged and chernístry determinations for so1ubilized elements by the surface drainage).Through the velue attained, the relations: betweeen pluvíoerosives intensity and power of transportatíons of the uncerciful materia1 were also regarded according to the particle dimension and degree of solubilization , of rnacro-nutrientes. The outcome demonstrated the expressive meaning of the vegetal covering-use of the ground, slope and flot·1ing form, as t·1ell as the hydraul ic behaviour of surface (the field capacity) in the pluvioerosive differentiation.
