Determinación, Análisis y Zonificación de Amenazas por Inundación en la Cuenca del Río Magdalena a la Altura del Municipio de Puerto Boyacá, Boyacá

Abstract

Puerto Boyacá is a Colombian municipality located in the Boyacá region, on the right side bank of the Magdalena river. Its terrain is dominated by flat slopes and its geomorphological characteristics are associated to alluvial ecosystems. These conditions, plus the inappropriate occupation of the territory, configure phenomena such as floods, which entail both social and environmental problems that jeopardise life and local economy. In this study, the threat of this phenomenon in Puerto Boyacá is determined, analysed and zoned, following the provisions of the Ministry of Environment and Sustainable Development with regard to the integration of risk management in Basin Management Plans – POMCAS. It was found that 39% of the municipality is at a medium level of susceptibility to flooding; that the threat of floods, classified as high, medium and low, predominates at this last level in 77% of the territory; and that in 10% of the urban area, in the neighbourhoods located on the banks of the Magdalena River, this threat is at a high level
