VERA RODRIGUEZ, Jorge Mario  and  ALBARRACIN CALDERON, Adriana Paola. Methodology for analysis of vulnerability for flood hazards, mass movements and watershed torrent flow. Cienc. Ing. Neogranad. [online]. 2017, vol.27, n.2, pp.109-136. ISSN 0124-8170.  https://doi.org/10.18359/rcin.2309.

Risk management is a fundamental component of the distribution of watersheds and, in general, for the integral administration of the territory. However, risk management exercises have been hegemonized from the partial visions of the natural and applied sciences, so they have focused mainly on the analysis of threats, giving less importance to the components of vulnerability. This work outlines a methodological proposal for the analysis and spatialization of the vulnerability to flooding threat, mass removal and torrential flows, supported by a holistic theoretical framework and the use of geographic information systems. This methodology was applied to a micro basin of the Combeima River, located in the department of Tolima. The obtained results allow verifying its practical viability, being also susceptible of generalization.

Keywords : Vulnerability; risk management; watershed; flood threat; mass removal; torrential flows.
