Erosive processes occur naturally and are essential for soil formation. However, they have been accelerated by anthropogenic actions, contributing to social, environmental, and economic damages. The aim of this study was to develop a methodology for the identification and quantification of soil loss using digital elevation models obtained through imagery from unmanned aerial vehicles (UAVs). In the three selected study areas in Te & oacute;filo Otoni - MG, the generated models were compared before and after precipitation events. The annual erosivity factor can be classified as very low, indicating regional characteristics of low erosive potential. This work proposed different equations for the use of Digital Elevation Models as a data source for the identification and quantification of soil loss through water erosion. The results obtained indicate that flights conducted up to 70 meters contribute to mapping quality and highlight the need for further studies to calibrate the methodology for quantifying soil loss and making it replicable in different situations.
