Problem 7
Water is flowing in a channel with a rectangular cross-section. The
channel has a uniform width of b 10 m, and it is equipped with a broad-crested weir.
The height of flow in a channel far upstream of the weir is h₁ 2 m, while the weir is

=
0.8 m above the bed of the channel.

1. Assuming the flow over the weir is critical, calculate the flow rate in the channel by
iteratively solving for the critical depth he. Perform at least 3 iterations. Did the flow
rate converge?
2. Given the water depth immediately downstream of the weir is 90% of the critical
depth hc, what is the water depth after the flow experiences a hydraulic jump further
downstream?
3. How much energy is dissipated by the hydraulic jump?
