Q4.A 1 m wide rectangular channel has a bed slope of 0.0016 and the Manning’s roughness
coefficient is 0.04. Uniform flow takes place in the channel at a flow depth of 0.5 m. At a
particular section, gradually varied flow (GVF) is observed and the flow depth is measured as
0.6 m. The GVF profile at that section is classified as
