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:
“The mighty river flowing dark and deep,
With ebb and flood from the remote sea-tides
Vague-sounding through the City’s sleepless sleep,
Is named the River of the Suicides;”

“Only men of moral and mental force, of a patriotic regard for the relationship of the two races, can be of real service as ministers in the South. Less theology and more of human brotherhood, less declamation and more common sense and love for truth, must be the qualifications of the new ministry that shall yet save the race from the evils of false teaching.”
—Fannie Barrier Williams (1855–1944)
