A uniform flow of \(110,000 \mathrm{ft}^{3} / \mathrm{s}\) is measured in a natural channel that is approximately rectangular in shape with a \(2650-\mathrm{ft}\) width and \(17.5-\mathrm{ft}\) depth. The water-surface elevation drops \(0.37 \mathrm{ft}\) per mile. Based on the computed Manning \(n\), characterize the type of natural channel observed. Also compute the Froude number and determine whether the flow is subcritical or supercritical.
