Abstract: The morphometric parameters of relief surface are essential for characterizing and understanding the landscape formation, especially in areas that have been undergone erosion and tectonic processes, as the case of the Sao Joao River Basin in southwest of Minas Gerais state. In order to recognize tectonic features that could interpose the development of the channel and ultimately affect the erosion cycles, were performed a series of geomorphological analysis, such as: isobase, factor transverse topographic symmetry and asymmetry of the drainage basin, and the curve and hypsometric integral. These results were produced through rates obtained by the TecDEM, software used to compile the entire procedure and routine, just using spatial information of the digital elevation model (SRTM). These analyzes satisfactorily gave the understanding of the structures and relief in the basin context, and thus, showing the topography and boundary areas, the erosive dynamic displacement of channels belonging to fourth and fifth basins orders, and finally the moment of transition relief.
