MAPEAMENTO E CARACTERIZAÇÃO DE OUTORGAS DE USO DA ÁGUA DA BACIA HIDROGRÁFICA DO ALTO RIO DAS ALMAS

Abstract

Due to the water crises that Goiás State has been passing recently, it is necessary to improve the management of water resources through the planning and consequent water rational use, regulating the demands, grants, conflicts management and multiple uses. Therefore, it is fundamental that the public agency responsible for water allocation develops a platform with a georeferenced database, enabling the user of the subsidies and flows available for the various uses in a given river. In this way, the objective of this work was to map and characterize the water allocation by the Secretariat of the Environment, Water Resources, Cities and Metropolitan Affairs. Secretariat of the Environment, Water Resources, Cities and Metropolitan Affairs - SECIMA, delimited in the Upper Rio das Almas Hydrographic Basin. A database was created by QGIS 2.18 free software through the delimitation of the Upper Rio das Almas Hydrographic Basin (BH) appling a plug in called TauDEM for hydrological analyzes. Concession flows were georeferenced and reclassified into available, alert and critical, according to Q95, the grant analysis methodology used by SECIMA. he obtained results were the map of flows granted from BH of the Alto Rio das Almas, the map of the classified flows reached 70.42% of available flows with compromise. It is concluded that the hydrographic basin has water availability of the outflows and that this information can contribute to a better management
