Estudio geomorfológico de la parte noroeste del municipio de Distracción, la Guajira, Colombia, definiendo las subunidades geomorfológicas presentes en la zona a escala 1:25.000.

Abstract

This project aims to define the subunits present in the northwestern part of the municipality of Distraction, La Guajira, Colombia, at a scale of 1:25,000 based on morphological and morphometric features and morphodynamic processes. For which a methodology was implemented that allowed the identification, analysis and interpretation of each of the subunits present in the area determined to carry out this study (area granted by the Municipal Mayor's Office of Distracción). This methodology comprises four (4) phases for which, in the first phase, the limits of the area and the theme that would be studied were determined, a bibliographical compilation of other works carried out and related to the theme of this study was made where they were downloaded some of the inputs (DEM, satellite image and cartographic bases) for the realization of the geomorphological map. A second phase where the detailed analysis of the information collected was carried out and, in turn, a preliminary map of the chosen area was made with the downloaded inputs to begin to understand the behavior revealed by the geoforms present in this area. A third where a field interpretation of the subunits present in the area was carried out and a comparison was made with the subunits reflected in the preliminary map. Finally, the fourth phase consisted of organizing all the information from the previous phases to obtain the final report of this project as a result, obtaining the geomorphological map where the subunits present in this part of the municipality of Distracción are defined, at scale 1:25000. The study area is characterized by three (3) geomorphological environments (Denudational, Structural and fluvial) which have a total sum of twelve (12) geomorphological subunits where the environment with the greatest presence in the area is Denudational with 56%. And the environment with the least presence in the area is the river with 20%.
