Zonificación de susceptibilidad por amenazas a escala 1:2.000 por movimientos en masa e inundación a partir de las características geológicas, geomorfológicas y cobertura del suelo en el asentamiento Juan Pablo II del municipio de San José de Cúcuta, Norte de Santander para su proceso de regularización y legalización.

Abstract

of San José de Cúcuta in the department of Norte de Santander, began illegally in 2005 and has maintained that condition to date, excluding it from the territorial planning plans (POT). . This context motivates the need to contribute to its legalization and regularization process through a detailed study on a 1:2,000 scale, as established by Decree 1077 of 2015. The work was structured in four phases. First, a literature review was carried out to collect data on flooding and mass movements in the settlement, complemented by the search for historical aerial images between 1991 and 2023. Remote sensing interpretation was then used to characterize the geology and geomorphology, maintaining the scale of the study. Subsequently, visits were made to the study area to collect data every 20 meters. In the last phase, a deterministic analysis was executed using map algebra, generating reports and maps to identify and evaluate past threats from mass removal and flooding. The results revealed that, although the settlement lacks steep slopes, implying low mass removal activity due to the flat topography, it is still prone to flooding. These threats were outlined and detailed in the analysis, highlighting the importance of specifically addressing the risks associated with flooding in the area. This study provides a crucial foundation for the legalization process and highlights the importance of considering specific threats in the design of risk management strategies.
