Example 2.16 A 2.5 m wide rectangular channel carries 6.0 m³/s of flow at a depth of 0.50 m. Calculate the minimum height of a streamlined, flat topped bump required to be placed at a section to cause critical flow over the hump. The energy loss over the hump can be taken as 10% of the upstream velocity head. Solution: Discharge intensity q = 6.0/2.5 = 2.40 m³/s/m Refer to Figure 2.22. Energy Line D V²/2, E₁ Yc2 Hump ΔΖ E₂ = Ecz 2
