Abstract

Dune systems are important multifunctional ecosystems for ecological balance and biodiversity. They are dynamic and fragile systems which require special protection, so it is essential to know how they have evolved over time. Most of the studies are based on making comparison between aerial photography due to the limited historical data available. In recent years, the use of data from LIDAR flights has made it possible to define the morphological units with greater precision and to determine the progress of the dune lines. Combining both sources of data using GIS techniques and DSAS software has already improved the results of the evolution of dune fields on other coasts of Spain. The study was carried out on the Salinas-El Espartal dune complex (Asturias). All available data from free sources have been downloaded, including aerial photography from 1957, orthophotography and LIDAR for the years 2014 and 2020. The results of this study show the degradation of the dune system, as 60% of the original natural area has been anthropized.
