The geomorphometric characterization and the land use of a watershed is important to understand the dynamics of the processes involving the hydrologic balance and sediment transport. In this context, the aim of this study was to characterize the morphometric attributes of the Upper Meia Ponte river watershed, trying to associate them with the predominant soil types and land use, and analyze the geometric similarity among the sub-basins that comprise it. At all stages of the study GIS programs was used, the IBGE topographic maps and Landsat TM5 satellite images and field surveys. The results showed that the sub-basin Sb2, predominantly Ultisols and Inceptisol, has a more branched drainage pattern and due to its shape and position in the landscape, is more prone to spikes in full in response to large rainfall intensities and is, therefore, more vulnerable to erosion and sediment transport.
