Geography and Environmental Studies

The issues that include shortages and management of water resources, this article aims to generate an imaging model of river basin Manatee, northeastern Pará, as well as the extraction of drainage network and order rivers.For this, we used techniques of GIS and Digital Elevation Model data (MDE) from Shuttle Radar Topography Mission (SRTM) obtained in TOPODATA database of the National Institute for Space Research (INPE) and morphometric characterization.The analysis and definition of the catchment and drainage system were obtained by software tools ArcGIS 10.1, (Hidrology module).With the results obtained it was found that the basin drain presented 1,034 square kilometers and 219.15 km perimeter, is characterized as a large bowl.Presented an elongated shape and which together with the evaluation of topography and hydrography rates, proved unfavorable to flooding, being ranked 4th order.The basin has a low drainage density, high permeability soil and small river density, with little winding canals and small slope and fork, and when it comes to river hierarchy.Thus, it is expected that this study on the dynamics of hidrogeomorfológicos processes can contribute to the rational management of land use in the catchment area of the river Manatee, aiming to provide subsidies to the basic guidelines of sustainable environmental actions.
