Additional thesis - The largest structure of the Dutch Delta Works, that protect the Netherlands against high water levels at sea, is the Eastern Scheldt storm surge barrier. The Eastern Scheldt barrier is constructed as an
open structure that can separate the Eastern Scheldt estuary from the North Sea. In case that water
levels of +3.00 m NAP are expected, the steel gates of the barrier close and the hinterland is protected
against floods. Besides the protective function of the barrier, the location also shows potential for tidal
energy extraction.
