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:

    Twilight and evening bell.
    And after that the dark!
    And may there be no sadness of farewell,
    When I embark;

    For though from out our bourne of Time and Place
    The flood may bear me far,
    I hope to see my Pilot face to face
    When I have crossed the bar.
    Alfred Tennyson (1809–1892)

    ... 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)
