WebFeb 7, 2015 · Manning coefficient n is a coefficient that represents the roughness or friction applied to the flow in the channel (Bilgin & Altun, 2008). In hydraulic engineering, Manning roughness coefficient is an important parameter in designing hydraulic structures (Azamathulla et al., 2013; Samandar, 2011; Bilgin & Altun, 2008). WebThe Manning formula factors are similar to those in Kutter formula and are expressed in the same units. Values for the coefficient of roughness, , were at first thought to be the same as those used in the Kutter formula but this assumption has been proven to be wrong.
