Stepped Spillway Prototype Operation and Air Entrainment: Toward a Better Understanding of the Mechanisms Leading to Air Entrainment in Skimming Flows | Journal of Hydraulic Engineering | Vol 148, No 11

AbstractA spillway is a conveyance structure designed to pass flood waters. The construction of steps down the steep chute may contribute to some energy dissipation, in turn reducing the size of the downstream energy dissipator. A unique opportunity for field observations was provided at the Hinze Dam Stage 3 (Gold Coast, Australia) between 2013 and 2021. Detailed observations were conducted for six overflow discharges within 20.9  m3/s
