Abstract: In recent years, society has experienced increasingly intense and recurring hydrological events of heavy precipitation. The study area has a history and ongoing occurrence of various flood events. The pluviometric event that took place on October 12, 2022, recorded a precipitation height of 120mm, triggering a flooding scenario that caused significant concern among the residents. The Lagoa do Sapo is in a topographical depression, making its terrain susceptible to such flooding, as all surface runoff is directed towards the lagoon. This study aims to explore the extent of flooding in the city through five precipitation scenarios, providing decision-makers with relevant information to address the issue in the city. The Storm Water Management Model (SWMM) software was utilized, and the model calibration was based on a simplified methodology employing two approaches. The first approach involved comparing the simulated flood extent with photographic records of the event, while the second approach utilized a program parameter, the continuity error, due to the lack of collected data during the flood event. With the calibrated model, it was possible to estimate the number of affected residences and the flood extents for different scenarios.
