Resumo

The fluvial forms represent the result of an extensive process of evolution of the drainage-basins under the action of the water. In this paper we calculated the values of some morphometric parameters and analyzed the relationships among these morphometric parameters as well as some hydrological parameters for seven river basins, located in São Paulo State (Brazil). All river basins presented dendritic drainage pattern. Area and perimeter were the parameters that showed the highest number of significant correlations with other morphometric and hydrological parameters. The morphometric data indicate that the river basins studied present a very permeable landscape, especially the AGUA, PEI, SJD and TUR river basins. Moreover, the geological basement (type of rocks) represents the key factor that differentiates the two main groups of river basins. Such differentiation could be shown through the morphometric and hydrological date.
