The coastal erosion sedimentary accretion and stability of the Caribbean Colombian coastline, has been evaluated. The study area is located between Barranquilla (Bocas de Ceniza) and Galerazamba Spit.
Using cartographic bases, air photographs and multispectral images of satellite SPOT and LANDSAT, it has been determined in a digital form, a general inventory based on the shifts of position and configuration of the coastline in the last 61 years. The information WdS processed with the Canadian program EASI/PACE (PCI) to determine in a qualitative way the variations of the coastline between 1935 and 1947 and to quantify in 'che last 10 years (1986-1996) the loss and gain of coastal lands and to compute the accretion and erosion.
Events of erosion and sedimentation have affected the low coasts causing morphologic changes in the configuration of the coastline, reflected in the migration of sandy bodies in direction to the south, causing the backward movement of the Ciénaga de Mallorquín bar, the disappearance of Isla Verde, the formation of Espiga de Puerto Colombia and the development oí the Flecha de Galerazamba throughout their length. The quickness (speed of 10m year) whereupon these morphologic changes took place allowed to catalogue therm like zones of sensitivity to the coastal processes. During the last 10 years throughout the coastal profile the erosive events have predominate on accretion ones.
