The Manning formula or Manning's equation is an empirical formula estimating the average velocity of a liquid flowing in a conduit that does not completely enclose the liquid, i.e., open channel flow. However, this equation is also used for calculation of flow variables in case of flow in partially full conduits, as they also possess a free surface like that of open channel flow. All flow in so-called open channels is driven by gravity. Websectional area by the mean velocity of water flowing through it (see Equation 6.1). 6.2.2 The Manning formula The mean velocity of water flowing in a channel can be calculated using the Manning formula (Equation 6.2). The Manning formula applies to steady uniform flow. For design purposes it is assumed that flow is constant and uniform. Flow
