Major Junction Structure Verified by Modeling

Two hydraulic models of alternative configurations of a junction structure involving two large water supply conduits were tested for efficiencies in mixing of the respective supply waters and for other hydraulic characteristics under a broad range of operational conditions. Both an open tower configuration having two concentric, vertical tanks and an enclosed piping cross configuration were model tested. The tower configuration was found to be more efficient in mixing and acceptable in hydraulic characteristics, provided certain baffling was provided. The engineering evaluation also favored the tower configuration, which was subsequently constructed and found to operate generally as predicted by the modeling.
