Análisis de la susceptibilidad a movimiento de tierra del tramo medio de la conducción Labrado Tuñi

Abstract

The bypass channel of the Labrado Embalse to the Tuñi reservoir, belongs to the “Complejo Hidroeléctrico de Machángara”, which is essential to generation of energy, watering and water treatment in the region. Along the bypass channel landslides take place that put the proper functioning of the channel at risk, for this reason the aim of this study is to make a landslide susceptibility mapping, covering the distance from the abscissa 3+000 to 4+500. In the study the information about the factors among the landslides were collected, verified and fixed to build the mapping, according to the Mora & Vahrson methodology and Analytic Hierarchy. After analyzing, it was determined the closer method to obtain mapping is Analytic Hierarchy, due its capacity to assign the differentiated weight to each susceptibility factor. Thus it is possible to establish the greatest influential factors to the landslide susceptibility are slope and precipitation. This study is expected to make a noticeable contribution to improve the control of the area and protect the infrastructure inside the “Complejo Hidroeléctrico de Machángara” bringing important benefits to the “Empresa Electro Generadora del Austro ELECAUSTRO S.A”
