Caracterización del comportamiento hidráulico del Río Ambato en el tramo comprendido entre el sector Tilulún y el sector las Viñas desde el km 8+00 al km 12+00 mediante un modelo matemático

Abstract

In Tungurahua province, in Ambato canton, Ambato river is located, one of the main Tributaries to national level, its water is used for various activities such as: irrigation and industries, etc. This Tributary presents a volume variation in its waters depending on the time of year, with periods of drought and water floods. Also, there are civil works along the river, for these a study of the hydraulic behavior of the Ambato River was relevant. The study of this river was carried out in the section between the Tilulún sector and the Las Viñas sector from km 8+00 to km 12+00, considering a length of 4 km. In the development of this project, various activities were carried out to collect: topographic and hydrological data. The information was then processed in the softwares: ArcGIS, HECGeoRAS and HEC-RAS. In the last program, the simulation of the flow in the River was carried out based on a mathematical model, where the different scenarios were studied. This project showed some results, for example; the behavior of the flow in the River for different return periods (years); with this, the places with flood zones were analyzed, where the construction of water storage and control works is necessary. The main characteristics of the river, the speed, the numbers of Froude and shear forces etc. were also evaluated. In addition, problems were found in the surrounding structures such as: bridges and with these, security measures will be applied to maintain and preserve them.
