Delimitation of watersheds and its morpho physiographic features are common practices used in hydrologic and environmental analysis. The aim of this paper was to analyze the Samambaia`s watershed and determine its morpho physiographic characteristics and track modifications made on land use throughout the years. Altimetry data was provided by SRTM radar program, compiled in a GIS created to store, process and analyze all the available data. A digital elevation model (DEM) was created from the SRTM image and used to delimitate the watershed. Final analysis of the morpho physiographic characteristics showed that Samambaia’s watershed has a low propitious for floods. The region also showed intensification of urban areas when considering the last 25 years (≈20%).
