The seven sandy islands of the Eastfrisian group would appear to be initially formed and now continually supplied with sand from the Westfrisian group and the mainland to the west. The inlets between these islands are in dynamic equilibrium with the strong tidal currents of the near 2,5 m range in the area. Hydrographic information dating back to 1650 permits the development of a hypothetical model which explains the historic changes and might predict future trends. The installation of coastal defense structures on the eroding western extremities of some islands in the mid 19th century has greatly influenced the bars by which sand is transported from island to island in an easterly direction.
