This problem is recurrent and is exacerbated by factors such as irregular topography, climate change, and a lack of territorial planning, which generates high vulnerability during the winter season. To assess this situation, a heuristic methodology was applied, combining qualitative and quantitative techniques such as observation sheets and surveys. Critical variables such as construction materials, state of conservation, and the location of buildings relative to the river were identified and weighted. The analysis included hydraulic simulations using IBER software, generating flood scenarios for return periods of 25 and 50 years. These simulations revealed maximum depths of up to 2.36 m and flows that can exceed 46.45 m³/s. The information was integrated using a Geographic Information System (GIS), allowing for mapping of risk areas. The results determined the buildings' vulnerability to be moderate, due to the use of materials such as brick and zinc roofs, as well as their average state of repair. Structural measures such as river dredging, wall reinforcement, and gabion construction are proposed, under the responsibility of the Bolívar Prefecture and the MAATE (National Coordinating Body for the Conservation of Natural Resources). Non-structural measures, such as land use planning, should be managed by the Municipal GAD (Department of Autonomous Government of Bolívar), while community and emergency plans are the responsibility of the Risk Management Secretariat. |
