A wide channel carrying a specific discharge of 32

/s/ft is laid at a slope of 12 X
. The channel has a Manning roughness coefficient of 0.01 8. The channel terminates into a free overfall at which the depth of flow is equal to 1.1 Yr Determine the depth of flow 400 ft upstream of the fall using the numerical integration method.
