Acesso em:.https://bdm.ufpa.br/jspui/handle/prefix/6508Water erosion is one of the factors that most contributes to soil degradation, its occurrence is influenced by several factors, such as rain, which cause various socio-environmental impacts. Thus, the objective was to carry out a survey of the most exposed erosive features and determine the rain erosivity factor for the municipality of Cametá (PA). The survey was carried out in November, considered a dry month that makes it easier to collect images. The rainfall erosivity factor, a component of the USLE (Universal Soil Loss Equation) model, was calculated using the historical series from 1994 to 2022. The average monthly rainfall erosivity presented values from 307.55 to 2,719.20 MJ mm ha1 h-1 month-1. Annual erosivity ranged from 17,445.44 (in 1980) to 19,118.38 MJ mm ha-1 h-1 year-1 (in 2022). The Rain Erosivity Factor (R component of USLE) was 16,781.97 MJ mm ha-1 h-1 year-1. Results presented were superior to those found in other studies, close to the study area and in other regions, with Cametá being considered an area with high erosion potential. All information obtained in the study can be safely used in nearby locations with similar climatic characteristics, which extends the possibility of use in planning both agricultural and urban activities.Acesso AbertoErosãoUSLESedimentosErosionSedimentsCNPQ::ENGENHARIASCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOLOGIATrabalho de Curso - Graduação - Monografia
