The Travelling Rubberducks

The Oosterschelde (Eastern Scheldt) is an estuary in Zeeland, Netherlands, between Schouwen-Duiveland and Tholen on the north and Noord-Beveland and Zuid-Beveland on the south.

After the North Sea flood of 1953, it was decided to close off the Oosterschelde by means of a dam and barrier. The Oosterscheldekering (Eastern Scheldt Storm Surge Barrier), between Schouwen-Duiveland and Noord-Beveland, is the largest of 13 ambitious Delta Works, designed to protect a large part of the Netherlands from flooding. A four kilometre long section has huge sluice-gate-type doors that are normally open, but can be closed under adverse weather conditions.
