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)

    ... social evils are dangerously contagious. The fixed policy of persecution and injustice against a class of women who are weak and defenseless will be necessarily hurtful to the cause of all women.
    —Fannie Barrier Williams (1855–1944)
