FLOW THROUGH SIDE SQUARE ORIFICES IN OPEN CHANNELS
A side orifice is a flow diversion structure which is widely used in irrigation works for diverting the flow from any main channel to its secondary channel. Analytical and experimental studies for flow through side square orifices in open channels are presented in this paper. Existing discharge equations for the side orifices are checked for their accuracy using the experimental data collected in the present study. The computed diverted discharges by the existing discharge equations were found to be inconsistent with the corresponding observed ones. Therefore, a new discharge equation is proposed in this study. The coefficient of discharge for the side orifice is dependent on the Froude number of the approach flow in the main channel and the ratio of width of the orifice to the width of the main channel. The computed discharges using the proposed equation were within ±5% of the observed ones.
