Análisis de la dinámica fluvial en el sector del coliseo Jefferson Pérez mediante modelación bidimensional

Abstract

The section of the Tomebamba River near the Jefferson Pérez Coliseum, in Cuenca city, has been considered one of the areas of greatest vulnerability to flooding, both in studies carried out and based on events that occurred. Thanks to technological progress, numerical modeling has been considered as the fastest and cheapest alternative to carry out this type of project. Two-dimensional numerical modeling is the most widely used for flood simulation. This degree work aims to study the river dynamics of the aforementioned sector, based on a two-dimensional model, Iber. For this, it is divided into two stages, the first, with a hydrological approach to obtain the design flows of the return periods of 20, 50 and 100 years, using the HEC-HMS program, and the second, emphasizes in the hydraulic part where the simulation is performed with the internal resolution of the Saint Venant 2D equation in the Iber program, using the finite volume method. For which, input parameters such as boundary conditions, Manning roughness coefficients and topography are entered. Finally, the results of the simulation with these flood flows are presented in the numerical model, in which the values of the draft and speed variables are analyzed, in order to prevent the safety of the population.
