(2018) Falcão, Cassiano José Lages Marinho; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/5445952042358738
This paper aimed to estimate laminar erosion susceptibility in Machados County – PE, achieved using the adapted Universal Soil Loss Equation (USLE) and SIG for computing and analyzing data. The methodology used can be split in five steps: collection and integration of rainfall data on a thirty-year interval, local topography analysis using geoprocessing tools, laboratory analysis and posterior geolocation of local soils physical parameters and the final computation through the adapted USLE formulae. The achieved results allowed surmising that the County’s soil loss susceptibility is low, but significant, with a mean value reaching 368t/ha.year. The biggest influential factor was the topographic factor, averaging (…). Soil erodibility was considerably high, with a mean value of (…) and rain Erosivity, found to be (…) had the lowest impact on soil erosion. It is also possible to perceive a considerable spatial variation from the results, despite the reduced area of study, endorsing geotecnology use on its determination.
