Simulación numérica bidimensional con el programa Iber del flujo de lahares primarios del río Santa Clara en la población de Sangolquí correspondiente al drenaje norte del volcán Cotopaxi

Abstract

The current work, has as objective to establish the goodness of the numerical model Iber, for lahar simulations in flood plains. It is justified the Iber use in lahar modelation because due to lahars that are going to be modelling, have rheological characteristics with hyper concentrated and granular flows, that can be modeling as a dilating fluid, whose results are very approximated, when they are modelling as a Newtonian fluid, it seems that lahar can be modelling as well as water, by manipulating the Manning n coefficient. For this case, are going to be two dimensional modelling the flow of primary lahars of Cotopaxi´s Volcano North flank in the Santa Clara´s river, specifically in the consolidated zone of Sangolqui, to that, entry conditions are going to be defined by the one-dimensional simulation of the upstream reaches with the Software Hec Ras, it is possible because these reaches have canoyed channels, which is ideal to the one-dimensional simulation. It should be considered that the simulation to be performed, is going to be under the consideration that the volume is constant along the reach and, it will be modeled to the Cotopaxi´s more probably stage.
