             abstract = "The purpose of this study is to generate a susceptibility map of 
                         the pollutants transfer from intensive pig farming to aquatic 
                         systems in Palmitinho County, northwest of Rio Grande do Sul, 
                         using cartographical data in a Geographic Information System 
                         environment. Our proposal aims to support pig farmers and 
                         municipal managers to define the priority areas for environmental 
                         management. The cartographic data used for the generation of 
                         Digital Elevation Model (DEM) were extracted from the topographic 
                         map of Palmitinhos in a 1:50.000 scale. The pixel size was 20 
                         meters. From the DEM was determined the Topographic Wetness Index 
                         (TWI) and the Topographic Sediment Transport Capacity Index 
                         (TSTCI). The TWI and TSTCI were reclassified into five classes and 
                         proceeded to the cross tabulation. The 25 resulting combinations 
                         were grouped into four classes (Low, Medium, High and Very High) 
                         considering the susceptibility of the pollutants transfer into 
                         aquatic systems. Subsequently, were integrated into the map the 
                         buffer with the permanent preservation areas along the 
                         watercourses and the buffer of the pig farms. The generation of 
                         the susceptibility map allowed the identification of priority 
                         sites for the implementation of conservation management 
                         techniques, being them the farms located close to water courses 
                         (punctual sources of pollution) and agricultural areas (diffused 
                         sources of pollution) where the pig slurry is applied as 
                         fertilizer, located along the water courses in a permanent 
                         preservation area.",
