An aqueduct is an artificial (man-made) channel that is constructed to convey water from one location to another. The word derives from the Latin words aqua, "water", and ducere, "to lead". Many aqueducts are raised above the landscape, resembling bridges rather than rivers. Sufficiently large aqueducts may also be usable by ships. They are similar to viaducts, but carry water instead of a road or railway. While a road bridge often carries the roadway at a more elevated level than the rest of the road, such a variation of height is not possible for an aqueduct.
