The main objective of this work is to evaluate the hydraulic behavior of the Quinual bridge located on the Quinualito creek in the department of La Libertad and thus preliminarily dimension the structural characteristics of the bridge in question. The problem arises because the existing bridge is in critical condition and is built with deteriorated tree trunk beams, causing partial interruption of transportation and a risk to the safety of the structure. It is important to carry out preliminary studies to help define the hydraulic design parameters such as maximum levels of extraordinary waters and scour levels for an adequate hydrological and hydraulic evaluation. For the present work, information such as topographic and cartographic surveys and hydrometeorological information (SENAMHI and ANA) was collected. With the information gathered, the geomorphological parameters of the microbasin were determined and the statistical analysis of the hydrometeorological information was carried out to determine the maximum 24-hour rainfall and the subsequent determination of the maximum design flow. Once the maximum design flow was obtained for a given return period and the hydraulic parameters and boundary conditions were identified, the HEC-RAS computational software was used in the current conditions (without structure) and considering the structure, to identify the behavior of the water profiles in the area where the new structure will be located. Finally, the scour was analyzed considering the analysis of general, contraction and local scour to determine the scour depth in the channel where the Quinual bridge will be built. The results obtained indicated that there is no overflow for the determined design flows and that the current location of the bridge is the safest for its implementation. Also, the scour determined indicated that there will be considerable erosion due to a central pillar that will be placed
