Aqueduct - This article is about the structure aqueduct, for the racecourse see Aqueduct Racetrack.
An aqueduct is an artificial (man-made) channel that is constructed to convey water from one location to another. Many aqueducts are raised above the landscape, resembling bridges rather than rivers. Sufficiently large aqueducts may also be usable by ships. They are a kind of viaduct, carrying water instead of a road or railway. While a road bridge often carries the road at a more elevated level than the rest of the road, such a variation of height is not possible for an aqueduct. Uses of aqueducts Historically, many agricultural societies have constructed aqueducts to irrigate crops. Archimedes invented the water screw to raise water for use in irrigation of croplands. Another widespread use for aqueducts is to supply large cities with clean drinking water. Some of the famed Roman aqueducts still supply water to Rome today. In California, USA, a large aqueduct runs in the central valley that transports water from Northern California to the Los Angeles area. In more recent times, aqueducts were used for transportation purposes to allow canal barges to cross elevations. During the Industrial Revolution of the 18th century, many aqueducts were constructed as part of the general boom in canal-building. In modern civil engineering projects, detailed study and analysis of open channel flow is commonly required to support flood control, irrigation systems, and large water supply systems when an aqueduct rather than a pipeline is the preferred solution.
