The Manning formula or Manning's equation is an empirical formula ... but one quarter in the case of a full pipe. It is a function of the shape of the pipe, channel ...
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]

Robert Manning. Robert Manning (22 October 1816 – 9 December 1897) was an Irish hydraulic engineer best known for creation of the Manning formula. Manning was born in Normandy, France, the son of a soldier who had fought the previous year at the Battle of Waterloo. In 1826 he moved to Waterford, Ireland and in time worked as an accountant.
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.
In civil engineering practice, the Manning formula is more widely used than Stricker’s dimensionally homogeneous form of the equation. However, Strickler’s observations on the influence of surface roughness and the concept of relative roughness are common features of a variety of formulas used to estimate hydraulic roughness.

It quantifies the impact of surface irregularities and obstructions on the flow of water. One roughness coefficient is Manning's n-value. [2] Manning's n is used extensively around the world to predict the degree of roughness in channels. The coefficient is critical in hydraulic engineering, floodplain management, and sediment transport studies.
