PROPOSAL FOR A METHOD FOR CHOOSING SAMPLE DRAINAGE AREAS AND THEIR RELATIONS WITH WATER VARIABLES IN THE SOUTHEAST REGION OF THE STATE OF SÃO PAULO - BRAZIL
Abstract
The objective of this work was to use statistical analysis to make the choice of watersheds to understand their respective hydrological regimes. The methods adopted in this work involved 6 steps, they being: delimitation of the sub-basins; calculation of morphometric indices; cluster analysis; choice of the sub-basins; collect of hydrological data; and relative analysis precipitation and flow rate. Based on the methods employed, four pairs of watersheds covering the Piracicaba River Basin (BHRP), located in the southeast of the state of São Paulo. The correlation analysis (precipitation and flow) by pairs of the watersheds allowed the obtaining of a preliminary diagnosis regarding the hydrological regimen of the areas, without the initial need to use other environmental attributes related to the physical environment.
