measurement of the beach width, documentation of its specific features, descrip-
tion of coastal sediment composition, sediment sampling for grain-size analyses,
and estimation of foredune condition. These field observations were analyzed and
calibrated with remote sensing data (aerial photos of 1959-1990, resolution 0.5 m;
Quick Bird space pictures of 2005, resolution 0.64 m) and with nautical and topo-
graphic charts in the scale 1:100,000-1:50,000 published in the nineteenth and
twentieth centuries. Retrospective analysis of old charts and remote sensing data
allowed defining shoreline recession areas, stable coastal zones, and accumulating
coastal segments. Therewith, it was possible to calculate average erosion/accretion
rates.
