The Chézy formula describes mean flow velocity in turbulent open channel flow and is used broadly in fields related to fluid mechanics and fluid dynamics. Open channels refer to any open conduit, such as rivers, ditches, canals, or partially full pipes. The Chézy formula is defined for uniform equilibrium and non-uniform, gradually varied flows.
For example, for a rectangular cross section, with constant channel width B and channel bed elevation z b, the cross sectional area is: A = B (ζ − z b) = B h. The instantaneous water depth is h(x,t) = ζ(x,t) − z b (x), with z b (x) the bed level (i.e. elevation of the lowest point in the bed above datum, see the cross-section figure).
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 ]
d = equivalent depth, a function of L, (Di-Dd), and r; r = drain radius (m) Steady (equilibrium) state condition In steady state, the level of the water table remains constant and the discharge rate (Q) equals the rate of groundwater recharge (R), i.e. the amount of water entering the groundwater through the watertable per unit of
