    The flow rate of the Tomebamba River is related to precipitation. When this phenomenon occurs in great magnitude, duration and frequency in the upper parts of the basin, crescents are generated that reach the city in the course of two to three hours (Basabe et al, 1996) producing a closure to the flow in the section where it is located a bridge and causing possible flooding. The lack of rigorous studies in its design stage demonstrates the need to verify whether the bridges over the river respond efficiently to the hydraulic capacity required to the passage of a rising. This paper proposes to analyze the hydraulic behavior of the bridges over the Tomebamba River included in the Balzain-Monay section. The methodology starts from the analysis of maximum flows for different return periods of 5,10,25,50 and 100 years. The characterization of the hydraulic parameters from a field survey and the hydraulic behavior of the section through comparison with an already calibrated HEC RAS one-dimensional model and the implementation of the IBER two-dimensional model. These data will be used to establish the capacity of hydraulic evacuation of each bridge to the passage of extreme events, define the importance class of the structure, obtain its required design flows and finally demonstrate the hydraulic deficiencies. In conclusion, this project constitutes a contribution to studies for the reduction of risks and disasters in the city of Cuenca that promotes the protection of its works and preserves its heritage value.
