Sažetak
Either due to reason of spatial restriction or economical optimization a weir in combined sewer often can't be carried out through classic form with one relatively long said weir. One of geometrically alternative solution is performing "U" shaped weir which enables augmentation of its relative length. Insufficiency of globally documented data related to hydraulic characteristics of such shaped weir, set demand for hydraulic model investigation on whole diversion plant with "U" shaped weir that is originally set for implementation to Zagreb City waste water discharge channel. Tests on physical model were focused on measuring speed and water levels at significant points in incoming and outgoing channels and diversion plant, with and without downstream inlet influence, and dependently on characteristic discharges of inlet channel at dry discharge to extreme discharge. Dynamic pressures were measured at weir wall and at stilling basin of overflow construction. Based on measurements, discharge coefficients and energy losses coefficients were calculated. The comparison between the velocities measured on physical model and one calculated on numerical model is also appended as like as comparison of discharge coefficients obtained on "U" shaped weir and classic side weir with similar dimensions. Certain modifications resulted with optimization of overflow functionality. Further more, analyses of the scam board removal efficiency of floating materials was carried out as same as their influence to upstream water surface elevation and decrease of discharge coefficient.
