It was determined in this work the morphometric characteristics of relief and drainage system of Rio Preto Watershed (RPW) to predict the area hydrological behavior. From delimitation of the watershed area, digitalization of the contour lines and from the drainage system, it was obtained the geometrical traits of the relief and RPW hydrography its six main sub-watersheds. It was concluded that the area presented elongated and narrow shape together with a high drainage density, evidencing lower risk of flood occurrence. On the other hand, it was observed floods justified by shallow soils caused by the intense process of deforestation and land use and by the rugged relief, with 73.1% of the area characterized from rugged relief to mountainous. Regarding the sub-watersheds, it was observed that less than 28% of the area was comprised by flat relief, facilitating water erosion.
