    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 de Tilulún y el sector de las Viñas desde el KM 0+00 al 4+00 mediante un modelo matemático

    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.
