WebDetermine the distance upstream where the depth is 2.5 m.The Manning coefficient is 0.025. Step-by-Step. Report Solution. Verified Answer. From Example 10.13, for a wide rectangular channel we found that N=3.33 and M=3. Therefore, one can calculate J to be. J=\frac{N}{N-M+1}=\frac{3.33}{3.33-3+1}=2.5. WebIn many cases, these calculation need adequate selection of channel roughness coefficient [4]. The Manning formula has been widely used to determine the roughness coefficient, n for open channels. The n value is a measure for surface roughness that affect the flow resistance. Small errors of this value can also give effect to the calculations.
