Stepped Spillway Flows and Air Entrainment
Stepped spillways have become a popular method for handling flood releases. The steps increase significantly the rate of energy dissipation taking place on the spillway face and reduce the size of the required downstream energy dissipation basin. The compatibility of stepped spillways with roller compacted concrete (RCC) and gabion construction techniques results in low additional cost for the ...

متن کاملModel Investigations of Stepped Spillway
Stepped block protection has considerable potential as a low-cost method for the construction of chute spillways and the protection of embankments from erosion by overtopping flow. Stepped spillways are structurally stable, resistant to water loads and significantly increase the rate of energy dissipation on the spillway face thus eliminating or greatly reducing the need for a large energy diss...
متن کاملsurvey the effect of downstream crest chute slope on the natural air entrainment point in skimming flow in stepped spillway
abstract stepped spillways are of most important hydraulic constructions to dissipation energy of water flow. these constructions are used in opening channel to transfer water from upper level to lower level. because of considerable effect of steps on flow dissipation energy and also the resulted developments in construction of roller competed concrete rcc, the mentioned constructions have draw...
