Incorporación de factores socioeconómicos al análisis de vulnerabilidad del riesgo por inundación en vías usando un modelo geoespacial.

Due to its geophysical characteristics and location in a tropical zone, Colombia is prone to flooding phenomena, which, in addition to the vulnerability of the road network and the permanent presence of the population residing close to the roads, increase the social and economic fragility of the road corridors. This situation is evident when traffic collapses due to flooding, as the country mobilizes most of its goods by land. The knowledge and systematization of the social and economic conditions of the national road layout, and the incorporation of these data into a replicable spatial model, could be an alternative for making decisions aimed at risk prevention. This paper presents the conceptual and methodological design of a proposal of the socioeconomic factors required in a road flood risk assessment using spatial analysis tools in the pilot section Route 6008 Chiquinquirá-Sáchica (36 km). A global index of socioeconomic aspects related to vulnerability is quantified at three levels: local, zonal and regional. The main result is that the road corridor presents a medium-high level of vulnerability, due to the aspects of exposure and fragility in housing and livelihood conditions. [ABSTRACT FROM AUTHOR]
