    Caracterización del comportamiento hidráulico del Río Ambato en el tramo comprendido entre el sector de Tilulún y el sector de las Viñas, km 16+00 al 20+00 mediante un modelo matemático”

    The present project is focused on determining possible flood zones near the Ambato River, by means of a mathematical modeling in the HEC-RAS program, considering some parameters such as the Manning coefficient, the slope of the land, among others. The study includes 5 sections from the sector of Tilulún to the sector of Las Viñas, with 20 kilometers in total. Specifically, this document will analyze the last section, that is to say from km 16+00 km to 20+00 km, where by means of orthophotos arranged by the Honorable Provincial Government of Tungurahua the topography of the place was obtained, which in turn allowed access to the current geometry of the River. The simulation in the HEC-RAS program was made with a base flow of 5 m3/s to calibrate the model, later with the calculation made by means of the hydrometric data the period of return of 122 years was entered to the software with the flow of 114.14 cubic meters per second, the last mentioned being used for the observation of zones of consideration for flooding. The importance of the project is to provide citizens, especially the relevant authorities and municipal or governmental entities, with flood maps, with which to take action to lighten or reduce the magnitude of the possible consequences, both for the habitants living on the banks of the river, the surrounding crops, as well as the nearby infrastructure.

    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

    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.
