| description |
This study was carried out in order to estimate the morphometric variables of the landslides found in Combeima river basin (Tolima, Colombia) and obtain possible statistical correlations. To obtain the morphometric characteristics of the landslides, we used a database with historical landslides, a RapidEye image from 2010 and an orthophotomosaic from 2009, where the landslides were visually identified. The morphometric characteristics were defined through a geographic information system and bivariate analyzes were ran between the morphometric variables to establish their correlations. The results allowed to identify 121 landslides, with an average area of 1,974.97 m2 and Birnbaum-Saunders type distribution. It was found that the slip area morphometric variable correlates with the total length (R2=0.9414), the length of the center line (R2=0.9368) and the width of the surface of rupture of this (R2=0.8915). These data could be used to infer the volume of the mass involved in the event and its potential effects . This result would allow the landslide area to be used as support in decision-making in the planning of the territory in the Combeima river basin. |

Para obtener las características morfométricas de los deslizamientos se empleó una base de datos con deslizamientos históricos, una imagen RapidEye del año 2010 y un ortofotomosaico del año 2009, en donde se identificaron visualmente los deslizamientos. Las características morfométricas fueron definidas a través de un sistema de información geográfico y se realizaron análisis bivariados entre las variables morfométricas para establecer sus correlaciones. Los resultados permitieron identificar 121 deslizamientos, con área promedio de 1,974.97 m2 y distribución tipo Birnbaum-Saunders. Se encontró que la variable morfométrica área de deslizamiento se correlaciona con la longitud total (R2=0.9414), la longitud de línea central (R2=0.9368) y el ancho de la superficie de ruptura (R2=0.8915) de este, y podría usarse para inferir el volumen de la masa involucrada en el evento y sus efectos potenciales.
