SUMMARY:

Inadequate management of stormwater causes various issues, such as flooding and inundation. The inefficiency of drainage systems, uncontrolled urbanization, and climate change contribute to the water management problem, resulting in economic, environmental, and social losses. In this context, this study analyzes surface runoff generation in part of the drainage sub-catchment XVI.5, located in the city of Natal/RN, near the Pitimbu River. Historical data and future projections from the regionalized MIROC6 model were used, considering future scenarios SSP2-4.5 and SSP5-8.5. The future scenarios indicated an increase in extreme precipitation compared to the current scenario, with an increase in average rainfall. Simulations in the PCSWMM software for light, moderate, and extreme rainfall events showed, through the outlet hydrograph, an increase of up to 11.9% in peak discharge for more intense events. Furthermore, analyzing two representative sub-catchments, it was found that the sub-catchment with approximately 92% impermeabilization presented the highest specific discharge values, highlighting the impact of urbanization. However, the sub-catchment with 95% vegetation cover resulted in lower specific discharge values, reflecting the influence of environmental preservation. These results highlight the need for adaptations in urban drainage infrastructure and the adoption of nature-based solutions (NBS) to mitigate the impacts of climate change in the catchment, while also reinforcing the vulnerability of urban areas to flooding events.
