Based on the Digital Elevation Model (DEM) of the TOPODATA project, there was data normalization, application of the HAND Model and subsequent classification of susceptibility. The mapping analysis was supported by satellite images, photointerpretation and systematic observations carried out in the field. The results indicate that 224.7 km² of the municipality of Jacobina is susceptible to flooding (10.2% of the municipal territory), with 41.8% high susceptibility, 41% medium susceptibility, and 17.2% low susceptibility. It is stated that the effective implementation of the Municipal Master Plan, with an emphasis on susceptibility and risk áreas, are pillars for sustainable environmental development.
