Amenaza por inundación en zonas del municipio de Campoalegre, Huila y su relación con la geomorfología

Abstract

The present research project aims to relate the geomorphology with the phenomenon of flooding that may occur in the municipality of Campoalegre, Huila, where there is much history of such phenomena, which affected the population. Based on this background, a study was generated based on the collection of secondary information from official sources, to establish the areas under flooding threat throughout the municipality and their relationship with the geomorphology of the affected areas, all this has been developed with geographic information systems to obtain maps of the areas most prone to flooding, as well as to explain the different geological formations that enhance the phenomenon. In this way, the Neiva River basin is determined as the area most affected by floods because its geomorphological formation is an alluvial valley which intensifies the phenomenon in which the main urban area of the municipality is affected and is considered relevant to implement actions aimed at minimizing the effects in accordance with the area’s own geomorphological characteristics.
