Flakket is a cuspate marine foreland on the north coast of Anholt in the Kattegat sea. It is composed of a number of gravel-rich beach ridges typically covered by aeolian sand and intervening swales and wetlands including a relatively large lagoon. The most recent evolution of the coastline of this marine foreland between May 2006 and September 2010 is documented in this paper. Flakket is under erosion on its northwestern side, which has retreated up to 40 m during the observation period. The shoreline of the northeastern side of the beach-ridge plain moved up to 70 m in a seaward direction during the same period.
