Abstract: Suggested values for Manning's n are found tabulated in Chow (1959), Henderson (1966), and Streeter (1971). Roughness characteristics of natural channels are given by Barnes (1967). During uniform flow in open channels the resistance to the flow is dependant on a number of flow and channel parameters. The usual practice in one dimensional analysis is to select a value of n depending on the channel surface roughness and take it as uniform for the entire surface for all depths of flow. The influences of all the parameters are assumed to be lumped into a single value of n. Patra (1999), Patra and Kar (2000), and Pang (1998) have shown that Manning’s coefficient n not only denotes the roughness characteristics of a channel but also the energy loss in the flow. The larger the value of n, the higher is the loss of energy within the flow. Although much research has been done on Manning's n, for straight channels, very little has been done concerning the roughness values for simple meander...
