1. Using the specific energy principle, calculate the discharge (in m²s^-1) through a sluice gate in a wide rectangular channel, with upstream depth y₁ = 0.44 m, and y₂ = 0.12 m.

2. A hydraulic jump occurs in a rectangular channel with a design discharge of q = 1.2 m² s^-1. The energy loss is ΔE = 2.2 m. What are the initial and sequent depths?
