Estimación de pérdidas de caudal y coeficiente de rugosidad del tramo comprendido entre el óvalo 01 al 11 del canal de riego Ambato - Huachi - Pelileo, cantón Ambato, provincia de Tungurahua

Abstract

The purpose of this project is to estimate the losses of the Flow and Coefficient of Roughness of the section between Oval 01 to 11 of the Ambato - Huachi - Pelileo Irrigation Canal, Cantón Ambato, Tungurahua Province. This experimental work began with the obtaining of the topography of the place of study, the determination of specific velocities and the flow that circulates through the channel under study, the realization of mathematical calculations to obtain the volumetric losses and the coefficient of roughness in the channel, finally the numerical modeling with the help of the HEC-RAS software. Topographic data were collected with the help of the Trimble M3 model total station. The specific speeds were determined with the help of the DMM-4000 model windlass, these were determined every 250 meters ensuring that said point is not located in any curvature of the channel, then with the help of several mathematical processes we determine the flow losses existing in the channel and the roughness coefficient raised in this. In addition, a numerical modeling was performed in the HeCRAS software to estimate its hydraulic behavior under different operating scenarios. The results obtained a volumetric loss value of 0.045 m3s higher than the minimum value referenced in the Uginchos method and an average value of 0.017 for the roughness coefficient equivalent to a concrete coating, according to Robert Manning.
