Water flows uniformly with a flow rate of 10 m'/s in a long rectangular open channel of 3.0 m width, Manning's n = 0.015 and bed slope of 0.00075. A broad crested weir of 1.24 m high is constructed in this channel. Calculate the flow depth above the weir, at just upstream and at just downstream of the weir. Sketch the hydraulic flow profile.
