                         compreende o Estado de S{\~a}o Paulo. A partir do MDE 
                         (Topodata-SRTM) com resolu{\c{c}}{\~a}o espacial de 1 
                         arco-segundo foram delimitadas microbacias hidrogr{\'a}ficas

                         the regional distribution pattern of geomorphometric variables of 
                         small drainage basins aiming terrain characterization in a 
                         regional (broad) scale. For this purpose were realized (1) the 
                         implementation of the calculation of geomorphometric variables of 
                         drainage basins using digital elevation model (DEM); (2) 
                         multi-scale evaluation of geomorphometric variables of drainage 
                         basin; (3) definition of homogeneous classes or regions from the 
                         distribution of the geomorphometric variables; and (4) analysis of 
                         the relationship between the variables and different terrain 
                         types. The study area comprises S{\~a}o Paulo State in Brazil. 
                         From the processing of digital elevation model (Topodata-SRTM) 
                         with 1 arc second grid, drainage basins (n=530) from 3 to 6 
                         Strahler order were delimited and a set of geomorphometric 
                         variables (n = 74) was calculated to characterize several aspects 
                         of each sub-basin, such as shape, relief and drainage structure. 
                         The redundancy analysis and aspects related to scale-dependency 
                         and spatial distribution were important to evaluate the variables 
                         and for selection of a smaller number of variables (n = 12). 
                         Ordinary kriging was used to create continuous layers and the 
                         respective geostatistic analyses were also used for the study of 
                         spatial variability of each selected variable. The definition of 
                         geomorphometrically homogeneous regions was based on the 
                         application k-means clustering on each layer. Most of the 
                         geomorphometric variables selected allowed the definition and 
                         characterization of large geomorphometric compartments (regions) 
                         in the study area. These compartments, in general, presented size, 
                         location and values related to the characteristics of the 
                         geomorphological provinces and to the main soils types. Drainage 
                         density, hypsometric integral, ruggedness number and mean channels 
                         length were the geomorphometric variables from drainage with 
                         higher correlation to the distribution and characteristics of 
                         relief and soils in regional scale.",
