• Abstract:

  Floods represent a real threat to populations, especially in peripheral areas, since deficiencies in issues related to basic sanitation aspects are still quite present, for example, basic sanitation. The problems related to floods occur mainly due to rapid and heavy rains, intense long-term rains, melting in the mountains and other climatic events, being intensified by environmental changes and urban interventions of anthropic origin. The present work had as objective to identify and map the areas of risks susceptible to floods in the urban zone of the municipality of Laranjal do Jari-AP. For this, IBGE shapefile and raster site files were downloaded, then the files were treated and maps were generated in the Qgis program version 3.4.15. According to the results obtained, four main areas with flood risk in the municipality were identified, being the neighborhoods: Malvinas, Samaúma, Santarém and Três Irmãos. These areas have the characteristic of being considered peripheral neighborhoods, being located on the banks of the river and in topographically lower areas, with the Malvina neighborhood being the most affected with floods that cause great damage to communities. Thus, the mapping of risk areas becomes relevant because they can support the construction of preventive and strategic action plans that aim to minimize the impacts resulting from floods.
