Resumen

The major problem currently presented by the arrival of the El Niño Phenomenon is flooding due to changes in meteorological conditions, causing damage to civil works such as bridges, roads, dams and reservoirs, irrigation canals, population centers, etc. This study aims to analyze flood areas caused by hypothetical burst flows from the Los Ejidos dam to the Andrés Avelino Cáceres bridge and along the Piura River channel. Hydraulic modeling is carried out using Iber software (version 2.5.2) considering three dam break flow scenarios using the equations of. Finally, this study demonstrates that the breakage flow of the equation presents a greater range of overflow with maximum velocities of 1.521 m/s, peak flow of 6795.3 m3/s, affecting the population of the city of Piura, Urb. Miraflores, Urb. Miraflores Country Club and Open Plaza, in addition to generating a flooding area of 50.79 hectares on the left lateral bank and 42.63 hectares on the right lateral bank in the Piura River channel. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2026.
