A 1m 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. At a particular section gradually varied flow GVF is observed and the flow depth is measured as 0.6m. The GVF profile at that section is classified as
