ANÁLISE MORFOMÉTRICA DA BACIA HIDROGRÁFICA DO RIO DOS PATOS, GO

Abstract

THE HYDROGRAPHIC BASIN IS FORMED BY A DRAINAGE REGION OF A RIVER AND ITS TRIBUTARIES, ITS GEOMORPHOLOGICAL CHARACTERISTICS INFLUENCE THE HYDROLOGICAL AND ENVIRONMENTAL BEHAVIOR OF THE SITE THAT IS LOCATED, BEING ASSOCIATED WITH PHYSICAL PARAMETERS OBTAINED BY THE MORPHOMETRIC CHARACTERIZATION OF HYDROGRAPHIC BASINS. THE MORPHOMETRIC CHARACTERIZATION EXPRESSED TO THE SOIL-SURFACE RELATION OF A HYDROGRAPHIC REGION, TAKES INTO ACCOUNT THE RELIEF, DRAINAGE NETWORK AND ENVIRONMENTAL PROCESSES THAT ALLOW TO ANALYZE THE GEOMORPHOLOGICAL CHARACTERISTICS OF THE REGION. BASED ON THE ABOVE, THE OBJECTIVE OF THIS WORK WAS TO PERFORM THE MORPHOMETRIC CHARACTERIZATION OF THE RIO DOS PATOS BASIN, GOI�S, USING THE CARTOGRAPHIC BASE OF THE STATE OF GOI�S IN THE SCALE 1: 250000, BEING CALCULATED THE COEFFICIENT OF COMPACTNESS, SHAPE FACTOR, DENSITY DRAINAGE AREA, CIRCULARITY INDEX, MEAN SLOPE OF THE BASIN, AREA AND PERIMETER OF DRAINAGE, AND THE ORDER OF WATERCOURSES, USING THE GEOGRAPHIC INFORMATION SYSTEM (GIS) AS AN AID TO ARCGIS SOFTWARE. THE WATER CATCHMENT AREA OF �€‹�€‹THE RIO DOS PATOS IS ELONGATED AND NOT SUSCEPTIBLE TO FLOODING UNDER NORMAL RAINFALL CONDITIONS.
