		<abstract>The study of the morphometric characterization is very important to understand the hydrological and environmental dynamics that occurs in the watershed. Thus, the present work aims at quantification for such morphometric characteristics (area, perimeter, length of all channels, drainage density, main course length, channel hierarchy, compactness coefficient, form factor, index of circularity, altimetry and slope) and from this, to carry out an analysis of the results presented with the purpose of determining the flood susceptibility, this data obtained were generated through the use of ArcGIS 10 software. In this way, to the geometric characteristics it was found 2,776.71 km² basin area, 392.79km perimeter, the coefficient of compactness was 2.36, the form factor was 0.17 and the index of circularity was 0.18. In relation to the characteristics of the drainage network it was found 542.66km extension of the water courses, 0.25 drainage density, 112.32km extension of the main river and the hierarchy of this watershed showed that the maximum classification of the channels was 4th order. In respect to the topographic characteristic, we identify that the hypsometric amplitude was 104 m and there is also predominance of flat surface. However, it was possible to verify that the watershed of the Caeté River has a low drainage density and according to the results of the topographic characteristic it was possible to determine that it has a low flow velocity and, in agreement with all the generated data, it was possible to classify the basin with low flood propensity.</abstract>
