    Estudio hidrológico – hidráulico del puente sobre el río Jadán, parroquia Jadán, cantón Gualaceo, provincia del Azuay
    (2013) Carvallo Corral, Pablo Andrés; Delgado Tapia, Jessica Carolina; Pacheco Tobar, Esteban Alonso
    This study provides an analysis of the meteorological, hydrological and hydraulic information to establish parameters and criteria that allowed the validation of the procedures of calculation and design for the bridge over the Jadán River located in Jadán, in the province of Azuay. The analysis incorporates a characterization of the morphological and hydrological drainage area of the project and a study of the hydraulic processes related to flow and scour. It has been determined a maximum precipitation in 24 hours of 72.3mm, with an intensity of 3.01 mm/h. In this concern it has been obtained as design flow the value of 215m3/s which corresponds to a return period of 100 years by the method of the SCS. For the study of flow it has been used the software HEC RAS through which have been given the maximum drafts, speed, and type of flow, applying as conditions of edge: the coefficient of roughness of the riverbed and the margins and the data of flow, obtained in the construction of the total hydrograph using the SCS method. It has been obtained heights of flow of 3.2m above the riverbed with a speed of 4.72 m/s. Finally for the characterization of scour it has used the method of Lischtvan - Levedliev which had been achieved an expected depth of 1.6 m. Through the study has concluded that the conditions of design established for the bridge that is already built, are consistent with the results obtained in this study
