Abstract

This article aimed to analyze the impacts of climate change effects, associated with rainfall patterns and intensity, on the urban drainage system projects of Joinville/SC. The research evaluated climate projections for global warming scenarios of 1.5°C, 2°C, and 4°C, applied statistical methods to identify trends in historical precipitation data, and compared current design rainfall intensities with newly projected scenarios. Through historical data and future projections, a comparative analysis of hydrological parameters for hydraulic network sizing was also developed. The results indicate a significant increase in rainfall intensity, showing that the city's current drainage system is undersized for both present and future climate conditions. The study underscores the need for sustainable urban planning and public policies to enhance the resilience of urban infrastructure to climate change.
