Design rainfall is a critical parameter in the planning of drainage and flood control systems. Makassar City is prone to inundation due to high rainfall and rapid urban development, necessitating an accurate analysis of design rainfall. This study applies the Gumbel and Log Pearson III distributions to identify the most relevant predictive approach for estimating design rainfall, which serves as a crucial foundation for drainage system construction in Makassar's urban area. The research examines rainfall characteristics in Makassar City—specifically around the Stamar Paotere station—where rainfall significantly impacts public mobility and the agricultural sector. Historical rainfall data were obtained from the local BMKG station for a specific period. The study evaluates and compares the reliability of the Gumbel and Log Pearson III distributions to identify the most suitable mathematical model for the computational analysis of precipitation data in the study area. The analysis results indicate that the Gumbel model yields the highest design rainfall estimates, whereas the Log Pearson III model produces slightly lower projected values. Nevertheless, both methodologies are applicable for estimating design rainfall, with the Gumbel method identified as the most suitable approach for implementation.
