Resumen:	The central objective of this research was to analyze the evolution of coastal erosion and sedimentation in the municipality of Dibulla, La Guajira (Colombia), over the period 2010–2024. The study aimed to characterize the most vulnerable zones and propose sound strategies for coastal environmental management, which can be utilized by municipal administration and other departmental and/or national entities. A quantitative method was employed, utilizing a non-experimental, longitudinal, and multitemporal design. The methodology relied rigorously on remote sensing and geospatial data analysis. Data collection involved processing multitemporal satellite imagery (Landsat and Sentinel), using techniques such as supervised classification and spectral index analysis (NDVI and NDWI) to delimit the coastline for the key years: 2010, 2015, 2020, and 2024. The multitemporal analysis evidenced a generalized retreat of the coastline in the municipality of Dibulla during the study period. The most significant erosion processes were specifically located in areas with high population density, such as urbanized and tourist zones. Notably, localized sedimentation processes were identified near river mouths, albeit to a lesser extent. The precision of the geospatial methodology allowed for the accurate characterization of these highly vulnerable zones.
