Caracterización del comportamiento hidráulico del Río Ambato en el tramo comprendido entre el sector de Tilulún y el sector de las Viñas desde el KM 0+00 al 4+00 mediante un modelo matemático

Abstract

This investigation is part of a macro project to know the hydraulic characteristics of 20 kilometers of the Ambato River. The first 4 kilometers from the Tilulun drinking water treatment plant were analyzed. Topographic data was obtained from the Honorable Provincial Government of Tungurahua to generate the geometry, cross sections and terrain characteristics in the ArcGIS program. The flows were provided by the Tilulun station over 17 years. In these data, the Chauvenet Criterion was applied to have the uniform sample, as well as the Gumbel Method obtaining the flow of 123,185 cubic meters per second and a return period of 261.20 years. The model was calibrated in the HecRAS Software with a base flow of 5 cubic meters per second, to delimit the natural riverbed. Manning's coefficients were entered to indicate the roughness. With all of this, we seek to know the velocities, cutting effort, and areas of flooding that will be reached when there is a rise in the flow and the damage that it will produce, and to propose places for the creation of structures that will diminish the damage that can be produced along the Ambato River.
