A New Formula for Critical Depth of the U-Shaped Channels
U-shaped section channel is widely used in water conservancy projects. But the critical depth computation equation for U-shaped section channel is a transcendental equation and no analytic solution. a formulae for calculation critical depth of U-shaped channels were derived by selecting proper variables and fitting curves. The existing graphic and trial methods were replaced. The engineering case shows that the proposed formulae are simple and accurate. The maximum relative error of the critical depth is less than 0.683%, It will be greatly convenient for the designers.
