Planteamiento de medidas prospectivas, correctivas y de adaptación ante la susceptibilidad y amenaza de inundación por desborde en el sector de la localidad de San Cristóbal en la Ciudad de Bogotá

Abstract

The main objective of the present research is to propose prospective, corrective and adaptation measures to the susceptibility and threat of flooding in the sector of the town of San Cristóbal in the city of Bogotá. The above developed through a GIS methodology and geoprocessing to generate the basic zoning of susceptibility and threat of flooding overflow in the locality. The obtained results were crossed with cadastral units at the level of neighborhoods, managing to represent up to 40.29 Ha with susceptibility "Very High" and 24.4 Ha with threat "Very High" by overflow in the town, where the neighborhoods with greater exposure to the risk of study are Chiguaza Rural, La Arboleda Rural, El Triángulo, Juan Rey Sur, San Blas II, Tibaque I and Tibaque Urbano. Their analysis led to the conclusion that intervention and adaptation actions in the locality should be improved taking into account the dynamics of the Fucha River in the face of precipitation as a trigger for the threat; strategies such as works that allow the incorporation of Nature Based Solutions (SBN) are of vital importance. Finally, the investigation allows us to conclude that the measures should be developed in more detail by the district entities depending on the scenario of flood risk in the town of San Cristóbal.
