Análise da erodibilidade de saprolitos de gnaisse

Abstract: RESUMOAs voçorocas são freqüentes em áreas com rochas do embasamento cristalino. A evolução destas feições é sempre fortemente condicionada pelos processos de erosão hídrica subsuperficial, embora os processos superficiais também sejam importantes. Este trabalho objetivou investigar os processos erosivos subsuperficiais atuantes nas voçorocas e compreender que fatores mineralógicos e texturais poderiam influenciar a erodibilidade dos saprolitos. Para tanto, foram realizados ensaios de caracterização e de avali… Show more

“…The characteristic of high erodibility of the C horizon or gneiss-originated soil layer (Morais et al, 2004), together with the soil morphological and topographical characteristics (profile) observed in the studied areas indicate the probable causes for the occurrences of gullies with great area and volume in this region.…”

“…Voçorocas constituem o estágio mais avançado dos processos erosivos, ocasionando a perda de solo com consequente prejuízo financeiro, social e ambiental (Morais et al, 2004;Guglieri-Caporal et al, 2011;Tedesco et al, 2014). Nessa situação, a realização de práticas mecânicas torna-se evidente, aumentando os custos de controle.…”

“…The Mortes River basin is located in areas with a predominance of granitic and gneiss crystalline basement rocks, covered by a thick layer of regolith, which is very susceptible to gully erosion (Morais et al, 2004). A significant portion of the basin is compromised by inadequate agricultural management and by roads improperly constructed, from mining activities with the presence of gullies and rills, which present a greater potential for sediment production (Curi et al, 1994;Sampaio et al, 2015).…”
