Análisis geoespacial para identificar las zonas susceptibles a inundación. Caso de estudio cuenca media del rio Sinú.

Abstract

70% of the electrical energy produced by Colombia comes from hydroelectric plants. After the setbacks and possible disaster risks revealed by the construction of Hidroituango, a deterministic evaluation and analysis is proposed to identify the affected areas after a possible flood in the middle basin of the Sinú River located in the municipality of Córdoba. Therefore, the identification of risk areas in the middle basin of the URRA dam is proposed through the use of digital cartography, evaluating the level of threat under topographic variables. Using the ArcGIS Pro software with information compiled from various sources such as satellite images, contour lines and lithology of the area to be studied, a weight will be given to each variable to obtain the affected area and the level of risk to occur. The development of an in-depth study of the problem of ignorance of flood threat areas in Colombia is proposed, a case study in the middle basin of the Sinú River after the URRA reservoir, where, being a remote area, there are no risk management plans that use cartography as a tool to identify this threat, as is the case of the municipality of Tierralta (municipal development plan 2020-2023). The above makes evident the little preventive planning that the state has in the face of latent threats.
