The Veerse Meer was separated from the North Sea by a series of what?
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.
Main ridge of the Taunus The main ridge of the Taunus (German: "Taunushauptkamm" ) refers to a 75-kilometre-long ridgeline in the High Taunus mountain in Germany, whose geological core consists of veins of hard Taunus quartzite and which separates the steeply descending Anterior Taunus to the south from the more gradually descending upland of the Hintertaunus or Farther Taunus in the north. The watershed between the Upper Rhine and River Main to the south and the Middle Rhine tributaries of the Wisper and Lahn to the north, runs for long sections along the main ridge. Several of the river flowing southwards have broken through the rock of the Taunus ridge unit in several places so that the watershed is diverted a few kilometres to the north.
