Summary: 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%.
