The hydrographic basins demonstrate variables and attributes that make them unique. Themorphometric method that permits the utilization of techniques to obtain the indexes of existingnumber relations among the attributes of a drainage basin makes the knowledge of the variouslinear, area and hypsometric variables possible, which, added to the variable qualitatives,multiplies the possibilities for space analysis. The results obtained by this method serve as acomplement an aid to better explain the interaction that takes place among all the landscapeelements. This being the case, in this study, some basic morphometric surveys are sought in orderto obtain better knowledge of the hydrographic basin of the Uberabinha river, which will make itpossible to subsidize its planning. To reach this objective, cartographic maps from IBGE and theimage from the satellite TM/Landsat 5 from INPE to the scale of 1:100000 were used and computerprograms AutoCAD Map R13 and SPRING 4.2 were used to make the calculations. From theresults obtained, it was verified that the principal source of the Uberabinha river is, in realityfrom the Beija-Flor (Humming-bird) creek and not from the Jacaré (Alligator) stream. The greatdifference in the density of the rivers between the upper and lower thirds of the basin was alsoconfirmed. Another important geomorphological conclusion is the fact of its being a young basin.
