Question: Derive an expression for the positive Surge / Celerity produced toward the upstream side by suddenly closer to the sluice gate in a barrage. A

Derive an expression for the positive Surge/ Celerity produced toward the upstream side by suddenly closer to the sluice gate in a barrage. A rectangular channel 4 m wide carries a discharge of 20 m3/sec at a depth of 3 m. Calculate the height and velocity of a surge produced when the flow is suddenly stopped completely by the full closure of the sluice gate. ASAP PLEASE
