    Caracterización geomorfológica a lo largo de la trayectoria de escorrentía para la estimación de la propagación de movimientos en masa
    (Universidad EAFIT, 2024) Martínez Osorio, Johan Steven; Ruiz Restrepo, Daniel Felipe
    Landslides generally propagate certain distances, threatening the lives of people and/or infrastructure not only at the origin site of the landslide but also along the propagation trajectory, therefore, it is necessary to estimate the maximum distance a mass could travel to assess the potential impact zone. There are empirical and numerical methods for estimating the potential propagation distance, with numerical methods being limited to specific landslides and potentially costly and time-consuming. Hence, empirical methods are useful for regional-scale studies, primarily relying on geometric correlations from the landslide origin point, but they do not consider geomorphological characteristics along the propagation trajectory. In this study, ten geomorphological characteristics (referred to as topographic barriers) were identified along the runout trajectory of landslides, significantly influencing the determination of the maximum reach distance of the mass. Since the influence percentage of these barriers depends on their location relative to the landslide's origin zone, a dominant weight with respect to the maximum propagation distance could not be established for most, but applicable relationships exist for curves, deviations, and opposing walls. Likewise, it is recommended to consider all geomorphological features for runoff analyses.
