MAPPING THE FLOOD RISK OF THE QUINTINO BASIN IN THE MUNICIPALITY OF BELÉM
Abstract
This research aimed to map flood-prone areas in the Quintino Basin, Belém do Pará, which faces adverse events such as floods, putting the population in vulnerable and risky situations. To generate the risk, the threat analysis was cross-referenced with vulnerability. The results revealed that the flood hazard area corresponds to 40.33% of the basin's total area, with 6.4% classified as high flood risk, 15.2% as moderate flood risk, and 18.7% as low flood risk. The neighborhoods of Jurunas (91.8%) and Condor (61.6%) were the most affected ones, with a larger extent of affected areas. Those neighborhoods also showed high socio-economic vulnerability, evidenced by indicators such as child population, illiteracy rate, and income. The risk analysis and mapping indicated that 40.33% of the basin's territory is affected by the risk zone, with Jurunas (91.8%) and Condor (61.6%) neighborhoods presenting the highest percentage of risk due to the previously mentioned high socio-economic vulnerability in those areas.
