Water flows down a spillway at a rate (per meter of width) of q = 5 m²/s and reaches thestreambed elevation horizontally. A hydraulic jump forms due to a mild slope conditionat the tail water, i.e., subcritical flow downstream. The flow velocity after the jumpobserved is v2 = 2.0 (m/s). Determine the water depth y₁ and velocity v₁ before thehydraulic jump and the loss of energy head (h) due to the jump?
