Utilização do QSWAT+ para delimitação da sub-bacia Ibicuí e da microbacia Cambaí: um relato comparativo quanto ao processamento em suas respectivas escalas

Abstract

A watershed can be divided into several sub-basins and micro-basins, and the use of these for modeling simulation is beneficial when different areas of the watershed are dominated by land use and occupation or soils with different properties, enough to impact the hydrology. Therefore, the objective of this work is the delimitation of the Cambaí stream micro-basin and the Ibicuí sub-basin, where it sought to highlight positive points and points to be studied and improved, regarding the processing and qualities of the products generated by QSWAT+. To this end, a study, analysis and interpretation of data was performed using the QGIS software and the QSWAT+ complement, where the most appropriate digital elevation model was determined, in order to better optimize the processing time and still obtain reliable information, determining the landscape units and water response, in addition to the delineation of the main and secondary beds, generating cartographic products such as map of the structures of the studied watersheds, land use and land cover map and finally the pedological map, enabling a comparative analysis of the use of QSWAT+ for the delineation of two different scales of watersheds.
