Manning’ s n values for flow open channel flow can be obtained sheet from standard textbooks such as Chowor Linsley et al. It usually occurs in the headwater of streams. Three Components of coefficient the Segmental Time of Concentration Method 1. A key assumption in the use of Manning' s equation is that uniform steady flow exists. This allows the Manning formula to correct for the effect of this roughness slowing down the water as it moves through the pipe sheet or conveyance. It is doubtful that high gradient forested sheet streams ever exhibit this condition.
