Abstract: The study of the physical characterization of watersheds is extremely relevant for the conservation and management of water resources. This present work aimed to study the physical characteristics of Rio Saltinho watershed, located in the cities of Cascavel and Santa Tereza do Oeste – PR. Using the AUTO CAD 2008 software, it was calculated the area to determinate the morphometric parameters, for the hydrological characterization of the watershed. It was indicated the order of the watershed watercourse and its hypsometric curve. The drainage area of the watershed is 42 Km² and the perimeter is 28,3 Km. The form factor of the watershed is 0,414, the index of compactness obtained was 1,22, indicating that the watershed shape resembles a rectangle; the index of conformation obtained was 0,3861. The watercourse slop was analyzed in three different ways: S1 0.0115, S2 0.00678 and S3 0.00610. The physical characteristics found on the watershed indicate that it is has low probability of flooding. Key-words: Watershed; Morphometric; Superficial runoff. Introduction Water consists in an essential element for life. Besides it direct consumption, it is necessary for food and resources production, both indispensible for life. The current rate of population growth has been forcing to increase exploited areas by the agricultural segment, one of the main responsible for the water consumption in the world,
