Canal cross section formula
WebFigure 10.2 shows the canal sections of this type with two standard side slopes. When r = 3.6 m or less, side slopes may be taken 1: 1 ADVERTISEMENTS: When r = 3.6 m side slopes may be taken 1.25: 1 Velocity of Flow: Mean velocity of flow may be calculated using Manning’s formula.

WebP = Wetted perimeter [L]. P is the contact length (in the cross-section) between the water and the channel. Q = Discharge or flow rate [L 3 /T]. R = Hydraulic radius of the flow cross-section [L]. S = Slope of channel bottom or water surface [L/L]. Vertical distance divided by horizontal distance. V = Average velocity of the water [L/T]. http://ecoursesonline.iasri.res.in/mod/page/view.php?id=124820
