The Chézy Formula is a semi-empirical resistance equation [1] [2] which estimates mean flow velocity in open channel conduits. [3] The relationship was conceptualized and developed in 1768 by French physicist and engineer Antoine de Chézy (1718–1798) while designing Paris's water canal system.
The Chézy equation is a pioneering formula in the field of fluid mechanics, and was expanded and modified by Irish engineer Robert Manning in 1889 [1] as the Manning formula. The Chézy formula concerns the velocity of water flowing through conduits and is widely celebrated for its use in open channel flow calculations. [ 2 ]

He was born at Neuilly.His father, Antoine de Chézy (1718–1798), was an engineer who finally became director of the École des Ponts et Chaussées.The son was intended for his father's profession; but in 1799 he obtained a post in the oriental manuscripts department of the national library. [1]
