“…TLS has functional sensitivity under adverse meteorological conditions [45] and a versatility that permits monitoring at any time. It has proven reliability on the coasts of the Cantabrian Sea in the study area, on confined beaches nearby, and in the ongoing observation of sand banks [42,43,46,47].…”

The dynamics and evolution of a coastal sandy system over the last 142 years were analyzed using geomatics techniques (historical cartography, photogrammetry, topography, and terrestrial laser scanning (TLS)). The continuous beach-dune system is a very active confining sand barrier closing an estuarine system where damage is suffered by coastal infrastructures and houses. The techniques used and documentary sources involved historical cartography, digitalizing the 5-m-level curve on the maps of 1875, 1908, 1920, 1950, and 1985; photogrammetric flights of 1985, 1988, and 2001 without calibration certificates, digitalizing only the upper part of the sandy front; photogrammetric flights of 2005, 2007, 2010, and 2014, using photogrammetric restitution of the 5-m-level curve; topo-bathymetric profiles made monthly between 1988 and 1993 using a total station; a terrestrial laser scanner (TLS) since 2011 by means of two annual measurements; and the meteorological data for the period of 1985-2017. The retreat of the sandy complex was caused by winter storms with large waves and swells higher than 6 m, coinciding with periods demonstrating a high tidal range of over 100 and periods with a large number of strong storms. The retreat was 8 m between December 2013 and March 2014. The overall change of the coastline between 1875 and 2017 was approximately 415 m of retreat at Somo Beach. The erosive processes on the foredune involved the outcrop of the rock cliff in 1999 and 2014, which became a continuous rocky cliff without sands. To know the recent coastal evolution and its consequences on the human environment, the combined geomatic techniques and future TLS data series may lead to the improvement in the knowledge of shoreline changes in the context of sea level and global changes.

“…However, if we observe the photogrammetric restitution of 2005, the large retreat of the coast in Las Quebrantas between 1988 and 2005 is seen. Since 2011, research was, therefore, centered on the area of Las Quebrantas, where TLS data were collected [42,43].…”

“…For example, the ongoing increase in mean annual temperature and the thinning of permafrost at high latitudes are promoting the expansion of shrubs across the Arctic and subarctic tundra (Tape et al 2006;Hallinger et al 2010;Myers-Smith et al 2011). Shrub expansion has also been observed in most mountain ranges and massifs across Europe at lower latitudes, where humans have used the subalpine and alpine grasslands for traditional activities such as extensive livestock herding (Roura-Pascual et al 2005;Anthelme et al 2007;Hallinger et al 2010;Targetti et al 2010;Ferré et al 2013) for many centuries or even millennia (Gassiot and Jiménez 2006;Pèlachs et al 2007;Gassiot et al 2016). The progressive abandonment of these practices in recent decades has favored the encroachment of shrubs into subalpine and alpine grasslands (MacDonald et al 2000;Dullinger et al 2003;Komac et al 2013;Ameztegui et al 2016).…”
