Most head and cross-regulators on the main or branch canals of the Egyptian irrigation network are of few vent number types which are considered as multi-vent regulators. Some gates from the multi-vent regulator could be closed during the maintenance period or low water supplies. This paper investigates downstream flow characteristics due to the submerged hydraulic jump (H.J) created by downstream (DS) multi-gate regulators for the various gate operating scenarios. The present study was carried out experimentally and theoretically by applying 1-D momentum and continuity equations in the longitudinal direction at control volume to estimate the relative depth of the submerged (H.J) that occurred DS of multi-gate regulators under probable multi-gate operation cases. Accurate equations are developed for forecasting the relative depth of submerged jumps. These equations could be applied in cases of symmetric and un-symmetric operations of regulators of multi-vents.
