What is Manning’s Formula? - Definition from Trenchlesspedia

While Manning''s Equation is similar to other formulas for determining the rate of flow (the "Q") within a channel, Manning’s Roughness Coefficient is a wild card. It represents the "friction factor" that occurs when friction exists (as it always does) between the sides and bottom of a channel, and the water flowing through the channel.
