In this paper, results of the three-dimensional morphometric characterization and the evolution of the sand dune systems (in the Salamanca Island National Natural Park), East shore of Magdalena River (department of Magdalena) in the Colombian Caribbean. The analyses carried out included an estimate of the superficial changes of the dunes (4.24 m/year of falling behind rate) that had taken place between the years 2005 and 2008 based on the digital field information (DTMs) obtained with the LiDAR sensor, as well as an evaluation of the falling behind rate of the coastline based on aerial photographs from 1961 and the ortho-photospectrum from 2008 (5.70 m/year). Finally, an estimate of the sand volume corresponding to the active dunes in a specific sector from 2005 and 2008, and the volumetric balance, was quantified through a DTMs difference.Downloads
