Profile of Distinguished Civil Engineer - Robert Manning

 Robert Manning (1816-1897) was an Irish engineer.

Though Manning did not receive any formal education or training in fluid mechanics or engineering yet he is known for creation of the famous Manning formula for open channel flow.

V = C R2/3 S1/2

Initially it was  in the form

V = 32 [RS (1 + R1/3 )]1/2

and developed as the best-fit solution for the data for velocity, slope and hydraulic radius obtained by seven best known formulae at that time.
