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 == hweir = 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.
