Evaluación de riesgos rfente a amenazas naturales en zona crítica del municipio de Mocoa

Abstract

The purpose of this project was to assess risks against natural hazards in the area of the municipality of Mocoa, for the development of these objectives 3 phases are identified, the first cataloged as knowledge of the risk that includes the identification of the threats that may affect the study area, the knowledge of the regional conditions, as well as the characteristics reported on important historical events and the prioritization of these scenarios, once this is done, phase 2 continues: evaluation of the susceptibility that for the purposes of this project is determined that a more detailed characterization of the threats due to floods and mass movements will be made and phase 3: risk or threat assessment The susceptibility to mass movements of the study area is the result of a combination of thematic variables of Geomorphology, Geology, Hydrology, use and land cover that resulted in the map of Susceptibility to mass movements at a scale of 1: 5000 that covers high, medium and low threat ratings The flood component takes into account the hydrological and hydraulic analysis for modeling in the IBER software, for subsequent zoning of the flood hazard zones for different return times, taking as a criterion the Methodological guide for the Elaboration of Flood Maps of the IDEAM and some geomorphological aspects.
