Determinación de vulnerabilidad en centros urbanos zonas de inundación

Abstract

Abstract: Floods are one of the most devastating natural hazards causing death, economic loss and property destruction. Flood vulnerability maps are a fundamental tool for flood mitigation and prevention and planning and intervention in risk areas. This study will estimatethe zones of vulnerability in the basin of the city of Lojafor wich an Analytical Hierarchy Process (AHP) and Geographic Information Systems (GIS) were changed. The factors used to generate the flood vulnerability map were topography, texture/permeability, land use and cover, geological/lithological units, and precipitation. From the 5 generatedmaps, a map of areas vulnerable to flooding was calculated. The results show that of the total area of 269.53 km2, 18.83 km2correspond to a vulnerability level without any influence, 135.63 km2to a low level, 111.66 km2to a medium level and 3.40 km2are within a high vulnerability level. The methodology applied in this study can be used in other regions with limited information.
