Study of Conveniency of Using Stepped Spillway in Roller Compacted Concrete Dams (RCCD) [PDF]
Engineering and Technology Journal, 2009 A suggested design of Bastora stepped spillway has been taken as a prototype to build a physical wooden model with scale of 1:20 (Lm/Lp). Experiments have been carried out on the model with slope of upward inclined steps of 420, 280, 140 and 00.

Aeration characteristics for skimming flow along the pre-aerator stepped spillways
Shui kexue jinzhan, 2014 Pre-aerator stepped spillways,where the aerator is placed prior to the primary step in the stepped spillway,can form a cavity chamber at the bottom to produce enough aeration concentration to avoid the cavitation erosion.
