Avertical lifting sluice gate is installed in a river channel to enable water removal for flood relief. The channel slope is mild. Channel is assumed to be rectangular with width of 19 m. The gate opening is 2.1 m, and the coefficient of velocity at the gate is 0.98 while the coefficient of contraction is 0.6. The depth immediately upstream of gate is 6.2 m. The stage discharge relationship for channel downstream of gate: Depth (m) 1.0 2.0 3.0 4.0 Discharge (m³/s) 45 99 156 233 340 5.0 Calculate the discharge through the gate, the significant depths, the total head loss caused by the structure, and the force on the gate. 2.1 m 23 4
