ANALYSIS OF RECTANGULAR SIDE SLUICE GATE

A side sluice gate is a flow-regulation device widely used in irrigation works for diverting the flow from a main channel to a secondary channel. The discharge of a side sluice gate may be obtained through the concept of an elementary discharge coefficient for an elementary strip along the gate length. Similar to the case of a normal sluice gate, the elementary discharge coefficient for a side sluice gate has been found to be a function of channel flow depth to the gate opening ratio for free-flow conditions. It depends on an additional parameter, namely, the ratio of the crest width to the gate opening for submerged-flow conditions, For a broad-crested side sluice gate, the discharge coefficient involves still one more parameter: the ratio of the crest width to the gate opening.
