             abstract = "Over the last decade, the free software for automatic delimitation 
                         of hydrographic basins has been showing significant improvements 
                         in results. This study had as objective the automatic delimitation 
                         of the Itapemirim River Basin (BHRI) using different free 
                         software. The acquisition of the data used in the processing was 
                         possible thanks to the Topodata project, which provided data on 
                         Digital Elevation Modeling (DEMs) and its derivations provided by 
                         Instituto Nacional de Pesquisa Espacias (INPE, 2011) at a scale of 
                         1: 250,000 for all national territory, these data were integrated 
                         and processed in a Geographic Information Systems (SIG) 
                         environment. The software used in the preprocessing was the QGIS, 
                         and for the processing were used the software Mapwindow and 
                         Terrahidro. The procedures performed consisted on the following 
                         steps: 1) flow direction, 2) flow acumulation, 3) drainage 
                         extraction, 4) Segments and vector segments, 5) watersehd 
                         delineation. It was possible to prove that the results obtained 
                         when automatically delimitating hydrographic basins in free 
                         software can be considered satisfactory for the areas in which a 
                         high slope index is presented, but in flat areas, only the Taudem 
                         processing returned excellent results, thanks to its better 
                         execution in the process of extraction of drainage in flat 
                         {\'a}reas.",
