A trapezoidal channel having a cross-sectional area A,, wettedperimeter P,, Manning's coefficient n and laid to a slope S, carriesa certain discharge Q, at a depth of flow equal to d. To increasethe discharge the base width of the channel is widened by x,keeping all other parameters viz., S, d, side slope and n same.Prove that1+Q,1+where Q, is the new discharge in the cdhannel.
