Local Scour Process in Conduit Aerated Water Jets
This study investigates the effects of natural aeration through pressurized pipes on jet-induced scouring downstream of hydraulic structures. Laboratory experiments with varying gate openings, flow rates, and water levels compared aerated and non-aerated jets. Increased aeration significantly reduced maximum scour depth and length, shifting the jet's impact point upstream. Scour depth and slope were highest in non-aerated jets, while aerated conditions produced shallower, flatter profiles. An empirical relationship for maximum scour depth showed high correlation (R² = 0.93), demonstrating channel aeration as an effective, safe, and economical method for scour reduction in spillways and similar hydraulic systems.
