		<abstract>Monitoring of watersheds is one of the main ways of studying the wanted and unwanted changes that occur in water resources (RENNÓ, 2004), it is such that watersheds are under protection of Federal Law nº 9.433/97 as a basic unit for their management. So, the aim of this research is to limit automatically starting from an MDE the sub-basins of second and fourth-order rivers in the watershed of the Manso River in MT and compare the representativeness of the rates that characterize the dynamics of their hydrological functioning to each order. The extraction and organization of the drainage network, as well as the limitation of the sub-basins were carried out through the use of an SIG based on a TOPODATA digital elevation model (VALERIANO, 2008). The most relevant results show 44 sub-basins for second-order rivers and 11 for fourthorder ones and, on the whole, these sub-basins present low density of drainage and low frequency of rivers, rates that favor infiltration in normal conditions of precipitation. It possesses a tendency to extended form and it is little susceptible to floods in normal conditions of precipitation. Some of the basin hydrological functioning rates (such as T, Dd, kC, Kf) displayed results significantly distinct among the fourth and second-order sub-basins. Thus, the conclusion indicates that the level of fragmentation of the watershed area of Rio Manso influenced significantly their hydrological functioning.</abstract>
