The discharge formula, Q = A V, can be used to rewrite Gauckler–Manning's equation by substitution for V. Solving for Q then allows an estimate of the volumetric flow rate (discharge) without knowing the limiting or actual flow velocity. The formula can be obtained by use of dimensional analysis.
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.

The momentum equation for open-channel flow may be found by starting from the incompressible Navier-Stokes equations : ⏟ + ⏟ ⏞ = ⏟ + ⏟ ⏟ + ⏟ where is the pressure, is the kinematic viscosity, is the Laplace operator, and = is the gravitational potential.
