Question

Consider a farm irrigation ditch in a loam soil having the following dimensions:

Bottom width, 0.5 meters.
Total depth, 0.60 meters.
Side slopes of 1 horizontal to 1 vertical.
Depth of water, 0.40 meters.
Cross-sectional area of the stream, 0.36 m²
Wetted perimeter, 1.631 m
Hydraulic radius of the stream, 0.22 m

QUESTION:

If the bottom of the ditch described in the previous problem (Problem 1) has a uniform slope of 1 meter per kilometer, and if the bottom and sides are kept smooth and free from weeds, what will be the mean velocity of flow and the discharge? Use n = 0.02.
