A lined rectangular channel with Manning's n = 0.015 is 5 m wide and has a flow depth of 2m with the bed slope of 1 in 1600. Retaining the rectangular shape of channel section and the same total area of lining, to what maximum extent can the discharge be increased without changing the bed slope? Does the flow change from sub critical to super critical state by this increase in discharge.
