Flood Barrier

A flood barrier, surge barrier of storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls, levees (also known as dykes), and other constructions and natural geographical features.

Surge barriers allow water to pass under normal circumstances but, when a (storm) surge is expected the barrier, can be closed. The means of closing can consist of various forms of gates.

Famous quotes containing the words flood and/or barrier:

    Men hold themselves cheap and vile; and yet a man is a fagot of thunderbolts. All the elements pour through his system: he is the flood of the flood, and fire of the fire; he feels the antipodes and the pole, as drops of his blood: they are the extension of his personality.
    Ralph Waldo Emerson (1803–1882)

    Clearly, some time ago makers and consumers of American junk food passed jointly through some kind of sensibility barrier in the endless quest for new taste sensations. Now they are a little like those desperate junkies who have tried every known drug and are finally reduced to mainlining toilet bowl cleanser in an effort to get still higher.
    Bill Bryson (b. 1951)
