Stepped Spillway Slope Effect on Air Entrainment and Inception Point Location
Water (Switzerland), 2021 Spillway is a crucial hydraulic structure used to discharge excess water from the dam reservoir. Air entrainment is essential to prevent cavitation damage on the spillway, however, without air entrainment the risk of cavitation over the spillway ...

Hydraulic performance of a pre-aerated stilling basin: Experimental study. [PDF]
PLoS OneSpillway chutes are critical in dam flood control, particularly in high dams where high water heads and large discharge in narrow canyons amplify the demand for safe discharging. For large unit discharges in spillways, aeration protection is essential to

Journal of Engineering Research and Technology, 2023 Stepped spillways disperse energy in floodwater by utilizing their stepping nature. Several researchers investigated the hydraulic and geometric relationships of the stepped spillway with a dam slope above 26.6o, which resulted in energy dissipation. But
