Effect of Using Weirs Downstream of Parallel Submerged Jets from Opened Multiple Sluice Gates

Ahmed M Nada


The design procedure of regulators recommends the installation of weirs to help in dissipating kinetic energy of water and controlling the hydraulic jump downstream. With the construction of new regulators, the weir downstream the old one is no longer needed and obstruct the water way.  These problems appeared downstream Rosetta and Damietta Barrages, for example. The objective of this paper is to study the behavior of weirs downstream of a hydraulic regulator with opened multiple sluice vertical gates.  The one Dimensional Simulation Model SOBEK will be used in this study. The regulator considered for this analysis is Tesaa Regulator which was built in 1832 and is located across Bahr Moues at km 36.0. The first scenario suggested changing the dimensions of the existing weir with the existing bed levels. The second one considered dredging the canal to the design levels and keeping the dimensions of the existing weir as is. The second scenario is considered to be more expensive than the first one. It was, however, recommended to adopt the second scenario as it preserves the old regulator which is considered an Islamic archeological structure.
