Chow et al mannings n

WebAs Manning’s n is usually assumed to be constant, this must mean that either velocity increases with slope or hydraulic radius decreases. The measurements showed virtually no increase in velocity and a minor increase in hydraulic radius with slope, as flow was more concentrated on steeper slopes. Webuniform flow acceptable in this case (Chow et al., 1988).
