             abstract = "The Universal Soil Loss Equation (USLE) mathematically describes 
                         the contribution of the most important factors in the soil loss 
                         process, and is the largest reference for estimating soil loss in 
                         Brazil. The objective of this article is to analyze the 
                         superficial erosion in the area under the influence of Dona 
                         Francisca hydroelectric power plant using a GIS-based model 
                         integrating USLE. According to the model results, the study area 
                         experienced a average soil loss of 935 kg/ha/year, which is 
                         considered low, when compared to other results. About 83% of the 
                         study area presented soil loss values between 0 and 1t/ha/year, 
                         and only 2% of the area showed loss soil values higher than 
                         4t/ha/year. The areas covered by agriculture and/or livestock, 
                         were the ones that contributed most to the formation of sediments 
                         (laminar erosion), due to the agricultural practices developed in 
                         areas of high slopes, as is the case of the cultivation of tobacco 
                         in hillsides. Regarding the cumulative effects of the variables 
                         composing the model, it is worth mentioning that the lack of 
                         vegetation cover associated with high slopes and intense 
                         precipitation are the conditions leading to higher soil loss 
                         values, which is worsen when combined to inadequate management 
                         related to non-conservationist practices.",
