Computation of discharge through sluices

While water flows though a sluice or gate following three conditions are possible

• Free flow condition
• Submerged flow condition
• Partially submerged flow condition

When discharge from the gate at its outlet (downstream side) falls free into atmosphere it is called free flow condition. It is said to be submerged if out let of the gate discharges under the water.
