Zonificación de la susceptibilidad por movimientos en masa del barrio Nueva Ilusión de la ciudad de Cúcuta, Norte de Santander.

Abstract

In this degree work in the modality of professional practices, a zoning of the susceptibility to mass movements is presented in an area of 1350 m2 in which the Nueva ilusión neighborhood of the city of San José de Cúcuta, department of Norte de Santander is located. . To carry out the methodology, the study was divided into the following stages; compilation of bibliographic information, interpretation of information taken from remote sensors, visual inspection of the study area, information gathering in the field, elaboration of thematic maps, final analysis and results. For the elaboration of the inputs, thanks to the topographic map of the area, which was provided by the Secretary of Disaster Risk Management of the city, a digital elevation model (DEM), slope map, shadow map was made, TIN surface and drainage network, which allowed the geomorphological interpretation, following the methodology of Carvajal (2012). In the same way, four Geomorphological Environments were determined; Anthropogenic, Denudational, Fluvial and Structural. In the field visits, five Superficial Geological Units were identified, where rocks from the Guayabo Group (Miocene) and Quaternary deposits predominate. Finally, the information was grouped and each variable was classified with a numerical value, where the higher the value, the greater the susceptibility, a percentage was assigned to each variable according to its level of influence in determining the susceptibility of mass movements, all of the above according to what was proposed by the Colombian Geological Service (SGC). Finally, the zoning of susceptibility due to mass movements of the total area was obtained as a result, where 29.7% corresponds to high susceptibility, and the remaining area to medium and low susceptibility.
