Estudio y caracterización hidráulica del óvalo 17 al óvalo 20 del canal de riego Ambato – Huachi – Pelileo, cantón Cevallos, provincia de Tungurahua

Abstract

For the execution of this project, we have started with a documentary research, where we have found the necessary information, formulas and required and important coefficients in the hydraulic characterization for a correct correlation of results in situ and numerical simulation. The in situ study was carried out in the first place, which consists in the topographic survey, measurement of cross sections, identification of the sectors and digitalization by means of AUTO CAD CIVIL 3D of the section under study that begins in the limits of the Parroquia Montalvo and the Canton Cevallos and ends at the intersection of the canal and the Yanahurco - Cevallos road and as the second step in the field study is the recording of speed data with the use of a flow meter and fluid velocity DMM - 4000 / PFT with which proceeded to the horizontal and vertical measurement of velocities to determine the flow behavior of the entire cross section of the 6 analyzed points. Based on the recording of speed data in situ, the calculation of speeds and average flow rates in each section is carried out using two methods. From the results we choose the most critical scenario, that is, the highest value. Finally, the simulation is carried out using the HEC - RAS software where we analyze the similarities and the differences of results in field and numerical, and we also identify by means of the Manning coefficient if the physical characteristics modified with the passage of time influence the hydraulic behavior of the numerical model.
