Resumo
The rapid population growth and the process of intense and disordered urbanization bring with them several environmental problems that may be related to conditions of susceptibility or the implementation of inadequate or non-functional infrastructure works. The main objective of this work is to identify areas subject to inundation as well as those susceptible to flooding in the Jaó sector, located in Goiânia, which has environmental aspects and infrastructures that enhance these processes. The methodological procedures selected to analyze the conditioning factors of possible floods and inundations involved the historical classification of urban land use and cover between 1965 and 2015; analysis of environmental variables, such as slope, orientation of surface runoff flow lines, field research of the conservation status of the microdrainage system. The results indicate that there is an increasing tendency of waterproofing in the sector and that the areas defined as subject to flooding were the low slope streets (0 - 6%) that present convergence of runoff flows associated with the absence or insufficiency of the functioning of the microdrainage
system. The area subject to flooding includes more than 50 occupied lots, 4 stretches of the sector's main avenue, among other areas along the water courses present in the sector
