		<abstract>Studies on the natural dynamics and the environmental vulnerability of a river basin make possible an analysis of the variation of the space and the elements of the hydrological regime. In this way, this study aims to analyze the physiographic characteristics of the Rio de Janeiro Basin from the use of geoprocessing and remote sensing techniques. To perform the physiographic aspects of the Rio de Janeiro Basin, a Shuttle Radar Topography Mission (SRTM) digital elevation model (MDE) was used to obtain the following physiographic characteristics: area, perimeter, total length of All channels, channel hierarchy, form factor, compactness coefficient, drainage density, altimetry and slope. The results show that the Rio de Janeiro Basin is not susceptible to flooding due to its elongated shape, it has many branches, because it is a 5th order basin, with several springs in low slope and high altimetry locations, characterized by rocks Of the Urucuia Group. The elevation and relief variation is significant in the eastern portion of the basin, where the highest slopes occurring by the mountain formation occur, which may cause a higher velocity and peak runoff. This analysis allowed to detail and individualize the physiographic characteristics of the Rio de Janeiro Basin at more detailed categorical levels and the generation of thematic maps, showing that the geoprocessing is an efficient tool for the analysis of the physiographic aspects of watersheds.</abstract>
