Delta Works The Delta Works (Dutch: "Deltawerken" ) is a series of construction projects in the southwest of the Netherlands to protect a large area of land around the Rhine-Meuse-Scheldt delta from the sea. The works consist of dams, sluices, locks, dykes, levees, and storm surge barriers. The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised.
Fromveur Passage The Fromveur Passage (French: "Passage du Fromveur" ), sometimes called St. Vincent's Channel, is a strait that lies between the island of Ushant and Kéréon lighthouse on Men Tensel Rock, off the coast of the French province of Brittany. It forms part of the northern limit of the Iroise Sea.
