Influence of aeration induced by piers on the starting position of the flow aeration and extreme pressures in stepped spillways

ABSTRACT The operation of stepped spillways is limited by a range of discharges due to the risk of occurrence of the cavitation phenomenon and erosion on its steps. Since there is a demand for spillways with the possibility of overflow of greater discharges, the designs seek to increase the air conc...
