Antoine de Chézy (September 1, 1718 – October 5, 1798), also called Antoine Chézy, was a French physicist and hydraulics engineer who contributed greatly to the study of fluid mechanics and designed a canal for the Paris water supply.[1] He is known for developing a similarity parameter for predicting the flow characteristics of one channel based on the measurements of another, known today as the Chézy formula.[1] 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] By the definition of open channel, the Chézy formula also applies to partially-full pipe flow.[3][4][5][6]
Chézy was born September 1, 1718, in
His son was orientalist Antoine-Léonard de Chézy (1773–1832).
