Design most efficient rectangular channel to safely carry a discharge of 15m³ /sec. The channel is to be constructed using concrete (Manning n= 0.013) and is to be laid at the natural slope of 300mm per km. Express your answers to the nearest mm. Sketch the cross section showing relevant dimensions. Is the flow sub-critical, critical or super-critical?
