The river Cricaré part of the river basin Matthew, one of the most important agricultural regions of the state of Espirito Santo. In this basin are the cities with the largest Brazilian production conilon coffee, pepper, papaya, macadamia nuts, eucalyptus, as well as livestock. However, its hydrological dynamics has been affected by human activities, causing many damages such as erosion, siltation and flooding. Thus, it is necessary studies and research that can assist in the analysis of the use and land cover dynamics, especially the geotechnology. Given the above, this study aimed to the morphometric characterization and mapping of land use in the Basin Cricaré River using GIS and remote sensing techniques in Geographic Information Systems (GIS). For that was generated initially the Digital Elevation Model hydrologically consistent (MDEHC) from TOPODATA project, available at INPE website in resolution 30 x 30m, and vectored hydrography. Subsequently they were obtained for the main physiographic study of the hydrological behavior of the basin. The relief is predominantly wavy and the average altitude is 348.73 m. The drainage area of 4538.02 square kilometers was found and the perimeter 615.58 kilometers. 3021 springs and 6268.67 km of water courses were identified. The Permanent Preservation Areas (PPAs) were defined from the viewpoint of environmental legislation, which represent 9.64% of the basin. The main form of land use in the basin is cattle ranching, with 55.92%. The preserved area with native Atlantic Forest is 19.02%.
