The objective of this study is to estimate extreme flood events in the Kallapuma sub-basin (Tacna) to design a bridge on the Kallapuma-Mamuta road, using HEC-HMS and HEC-RAS models. The region’s vulnerability to floods, exacerbated by climate change and the El Niño phenomenon, underscores the importance of adequate infrastructure. The theoretical framework includes hydrological modeling methodologies, such as the use of the Curve Number (CN) to calculate runoff, and highlights the impacts of extreme precipitation in southern Peru. In the project development, HEC-HMS is used to simulate the basin with maximum precipitation data and IDF curves, while HEC-RAS evaluates flow behavior and water surface profiles in the proposed bridge. The results indicate a maximum flow of 14.4 m³/s for a 140-year return period, with water depths ranging from 0.20 to 1.5 m and a scour depth of 0.88 m. Simulation accuracy is validated with indicators like Nash-Sutcliffe (0.84) and RRMSE (0.16), suggesting improvements in water management, including the installation of automated stations and sediment studies to strengthen the models used
