Cambios en las coberturas de la tierra en el periodo 1984 – 2017 y análisis de la amenaza ante inundaciones en el municipio de Campo de la Cruz, Atlántico- Colombia

The present study had the purpose of evaluating the changes produced in the land cover and land use generated by therainy season floods of the Campo de la Cruz municipality, located south east of the department of Atlantico, Colombia.Therefore, a supervised classification of the territory was carried out, through the use of geographic information systems (GIS),to identify the coverage areas of the municipality between the periods 1984 - 2017; using the CORINE Land Cover method toinvestigate these phenomena. The results highlight that during the period 1987 - 2007 the natural vegetation increasedsignificantly by 993.6 ha; on the other hand, during the period 2007 - 2012 there was greater affectation after the flood thatoccurred in 2010, reducing by 2685.6 ha. Additionally, it is important to highlight the identification of a significant crop increaseof 22.13%, in the study period, in contrast to the loss of pasture land; and in a complementary way, 31 extreme events ofmaximum flows associated with the occurrence of the La Nina phenomenon were found. Consequently, based on the analyzescarried out, it was possible to conclude that the high threat increases progressively in the most susceptible covers such as baresoil, crops and the populated area.
