             abstract = "This study estimated the annual loss of soil distributed on a 
                         catchment, located in Cariri, Cear{\'a}, using GIS and USLE 
                         quantitative model in an integrated form. Delimited to the 
                         catchment area of S{\~a}o Jos{\'e} - BHSJ through the digital 
                         elevation model of the Shuttle Radar Topography Mission - SRTM 
                         using Arc Hydro® Tool Arc GIS® software. Soil losses were 
                         estimated by USLE. The maps generated for the parameters R, K, LS 
                         and C are obtained from data spatially. The factor P was admitted 
                         as 1.0 because there were no measures to control erosion. To 
                         evaluate the results of soil loss with susceptibility to erosion, 
                         the values obtained were classified according to levels of 
                         susceptibility to erosion. Most erosivity was calculated in EP3 
                         (1,804 MJ mm ha-1 yr-1), due to higher rainfall recorded this 
                         season. The use and occupation of land presents undergrowth next 
                         to the beds of rivers due to intense exploitation of these areas 
                         for agriculture. The area of conurbation between Crato and 
                         Juazeiro shows the transformation of this growing rural urban 
                         basin. The geoprocessing tools to perform a fast parameterization 
                         allowed the factors of USLE. The use of SRTM for obtaining the 
                         topographic factor proved to be a good alternative, since 
                         obtaining such factor is time consuming manual way. Unprotected 
                         areas of vegetation and hillside areas with high slope present 
                         themselves as the most susceptible to erosion.",
