The development of the westernmost part of the Wadden Sea in historical time in Geomorphology of the Wadden Sea area, final report of the section Geomorphology of the Wadden Sea Working Group.
The history of this part may serve as an example for the development of other parts of the Wadden Sea. Historical information on this area dates back to Roman times, but until the 10-12th century the data are very scanty. In the 15th and 16th
