Assessment of the environmental degradation susceptibility of the Macaé River Hydrographic Basin with support of geoprocessing

Abstract

This article presents a thematic exploration of the environmental degradation in the Macaé River Hydrographic Basin. The objective was to provide a cartographic base on relevant issues regarding the Basin, by doing environmental assessment with support of geoprocessing. This aims at providing assistance for public actions in environmental decisions, and suggest applications of data in local and/or regional plannings that may support the development of the Basin Plan. The AHP method – Hierarchic Analytical Process – was used. The resulting map shows the areas of potential environmental degradation, in which those with greater susceptibility are located at the top and middle sections of the river, and the less likely are found on its lower course.
