Evaluación de la Amenaza por Inundación del Río Ariguaní en el Área Urbana del Municipio Algarrobo —Departamento del Magdalena—

Abstract

The objective of the research is to evaluate the natural threat of flooding of the Ariguaní River. It is focused on a sector of the urban area of the municipality of Algarrobo. It is considered to be an important input for the comprehensive risk management of the municipality. The Territorial Planning Scheme, which is currently outdated, must be considered in the basic risk studies. The study includes the application of two methodologies for determining the threat. The first methodology incorporates local knowledge through the use of participatory tools regarding flood levels and sites from the imagination and experience of the inhabitants. The second methodology addresses hydraulic analysis based on historical flow data using specialized software for mathematical and geostatistical modeling. Finally, the study provides a comparative analysis that validates the use of community information vs. analytical information.
