A trapezoidal channel is designed to carry 25

/s on a slope of 0.0015 m/m. The channel is unlined, and in order to prevent erosion, the maximum allowable velocity is 1.5 m/s. The side slope must be no steeper than 2H on 1 V and the Manning n value is 0.03. In order to meet these requirements, what flow depth and bottom width should be used?
