Abstract

Human intervention in soils through agriculture and livestock farming can result in the exacerbation of erosion processes. This article discusses the influence of reforestation and pasture on a gully system, analyzing how land use patterns affect the gully sidewall. The study area is in Analândia (SP) and is a tributary of the Santa Terezinha Stream (Corumbataí River Basin). The gully system was imaged over four trimesters by an unmanned aerial vehicle (UAV). Land-use patterns were classified using the Support Vector Machine (SVM) algorithm (QGIS 3.16). Detailed land cover classification revealed the complex dynamics of the gully, with discernible variations influenced by seasonality, vegetation changes, and precipitation patterns. It was concluded that gully evolution is not strictly linked to precipitation but is significantly influenced by the surrounding vegetation cover.
