The evolution of the barrier-spit terminus of Skallingen was analyzed on navigational charts and aerial photographs. Between 1654 and 1905, the barrier spit Skallingen built up from a nonvegetated dry sandy ridge to exhibit extensive aeolian dune ridges. After 1910, the barrier-spit terminus slowly started to erode and, between 1945 and 2000, barrier-spit terminus eroded almost 2 km toward the northwest, in the opposite direction of the littoral drift. Cut-off of the sediment bypassing and dredging of the tidal channel is found to be the main reason for erosion of the barrier-spit terminus. Storms have affected the west coast of Skallingen and its barrier-spit terminus very differently, as most erosion at the terminus took place before 1981 and erosion on the west coast mostly took place after 1981. Contemporary with the erosion, a flood tidal delta appeared and it has migrated 1740 m since 1974. The front of the flood tidal delta has increased in height and is close to mean high water spring, and about 380,000 m³ of sediment was deposited within this flood tidal delta east of Skallingen between 1990 and 1999.
