Abstract

The morphometric characterization in watersheds allows evaluating the behavior of these areas, providing important data for planning and preservation of natural resources. This study aimed to characterize the morphometry of the Stream Patos watershed, Bofete - SP, located between the coordinates 48º 07 '03 "to 48 16' 53" of longitude WGr. and 23o 00' 16" to 23o 03' 39" S latitude, with an area of 3810,87ha. The results showed a watershed 4rd order branching channels and low drainage density (1.3km/km2). The conformation index (0.35), form factor (0.40) and the coefficient of compactness (1.37), indicate elongated shape. The sinuosity index of 1.35 indicates a tendency to rectilinear channels with a extent of surface runoff route of 384.61m. The average slope is 16.48%, ranking as undulating relief. Dimensional parameters along with the standard drainage network morphometric indices of shape, relief, composition and allowed to infer that the area has low susceptibility to flooding and erosion risks.
