Ítem Acceso Abierto “Análisis hidráulico de los puentes sobre el río Burgay sector la Concordia”(Universidad Católica de Cuenca., 2023) Cabrera Guillén, Boris Fabricio; Vélez Vázquez, Vinicio Valentín; Vintimilla Ulloa, Cristian Arturo; 0302633615; 0350018388; ., .Over the years, bridges have suffered structural damage due to the events caused by climate change, such as major floods, so it is necessary to evaluate not only the structural factors but also the hydrological and hydraulic aspects. This research is focused on assessing the stability conditions of the bridges of “16 de Abril” Avenue, “La Concordia” sector, by modeling the hydraulic behavior of flow with an extreme event corresponding to a return period of 100 years and comparing it with recurrence times of both 25 and 50 years. To achieve successful modeling, field studies, flow gauging, bathymetry, and topographic surveys were conducted to establish the geometry of the area, together with the calibration of the one-dimensional hydraulic model HEC-RAS. This investigation showed the flow behavior with a flow variation for 47.9 m^3/s for 25 years, 59.5 m^3/s for 50 years, up to a maximum of 85.6 m^3/s corresponding to a return period of 100 years. Finally, as a result of the analysis, it was assumed that the bridges under study are hydraulically stable. However, to protect the foundations from the high velocities, options were recommended that can be implemented in future projects as long as they are verified with physical and mathematical models.
