MORPHOMETRIC CHARACTERIZATION AND LAND USE AS PLANNING AND MANAGEMENT INSTRUMENTS OF THE MAÚ RIVER RIVER RIVER SUB-BASIN IN THE NORTHEAST OF PARÁ

Abstract

The present work aims to carry out the morphometric characterization of the Maú river basin - located in the northeast of Pará - based on geoprocessing techniques, thus providing subsidies to its management. The results obtained demonstrate that the sub-basin has a low susceptibility to floods and its morphometric indices such as: shape factor, circularity index and the compactness coefficient indicate that the Maú river sub-basin has an elongated shape that contributes to not natural degradation. Analyzing the use and occupation in the sub-basin, the significant anthropic influence was evidenced since 48.61% of its area is occupied by agriculture, indicating a concern with the conservation of the sub-basin.
