Análisis de las zonas urbanas con mayor amenaza por inundación de la microcuenca del Río Frío en el municipio de Floridablanca sector Santa Coloma y barrios aledaños por medio del uso de un SIG

Abstract

This research is based on analyzing the urban areas most threatened by flooding in the Río Frío micro-basin, starting from the collection of data such as rainfall, cartography and demography of the study sector extracted from the databases of the entities. responsible for this information and then by using the tools of the Geographic Information Systems GIS such as Quantum Gis and HEC-RAS for the generation of maps and dynamic models of the flood events that have occurred and those that could occur, which allow to categorize the threat and also classify the probability of said flood. The results obtained from the dynamic models and flood maps allow not only the comparison of the events with each other, but also with the studies carried out by the government entities in charge of flood risk prevention, giving rise to a more in-depth analysis of the behavior of these flood events allowing to identify the affected areas of the sector if an event of the magnitudes studied in the investigation were to take place.
