A canal of rectangular cross-section and an n=0.030 is to be laid on a slope of 0.002 and is to carry a discharge of 30 m3/s. Calculate the cross-sectional area required for the channel to carry this flow based on the normal depth for the following values of the ratio B/y: 1.0, 1.5, 2.0, 2,5, 3.0, and 3.5. Here, B is the width of the channel and y is the flow depth. Then, plot these values of the waterway area against B/y. What do you think is the best ratio of B/y to use in your design of the canal?
