Resumo
This work aimed to evaluate the process of urban occupation and its influence on the morphological behavior of the Barreiro Creek Basin, located in Goiânia - GO, analyzing its current arrangements for use in contrast with the characteristics of different periods of the physical environment. The methodology adopted evaluated the spacetime between changes in coverage and urban land use/land cover (LULC) between 2006, 2012, 2016 and 2019 and the behavior of the channel morphology, in view of the increase in waterproofing rates. The classes Waterproof, Non-permeable, Green Area, exposed were identified, while the class Non-permeable presented a drop and the class Green Area presented several answers. The increase of the Solo exposed class is related to the growth of the urban area in the study basin. A granulometric analysis of soil samples was also performed and the analyses showed a greater presence of sand followed by silt, configuring materials with light texture, which disintegrate easily and are loaded with flow. The results indicate how the impacts of urbanization interfere with the watershed.
