Simulación numérica bidimensional del flujo generado por la rotura de una presa y análisis de la zona de afectación utilizando el software Iber, caso en estudio: Presa Chiquicahua ubicada en el cantón Ambato, Provincia de Tungurahua.

Abstract

The purpose of this study is to identify the affected areas due to the failure of the Chiquicahua dam,highly relevant information that will serve to prepare emergent or contingency plans due to the probability of occurrence of an extraordinary event. The program used is Iber, a free-use software that allows numerical simulation of flow in rivers. For this, several points of interest are identified such as buildings with a greater flow of people and civil infrastructure of various services to determine the degree of affectation. Different scenarios are proposed to determine the areas that will be flooded and the danger that entails; the classification of the degree of danger will be governed by international standards as the Spanish code RD9/2008 and the American code FEMA, so it allows to differentiate the different classification modes of each code, as well as determine maximum velocities, maximum depths, Froude number and erosion and sedimentation processes in the study area.
