Three Gorges Project dam - Trash sluice operation in 2004

View from the left bank of the high-velocity air-water jet coming out of the sluice system. The white waters highlight the strong self-aeration of the turbulent water jet issued form the bottom outlet system. Trash sluice operation at the 3 Gorges Project dam, Yichang (China). Total head: H = 70 m; Jet velocity: V = 35 m/s - Video taken on 20 October 2004.
The strong turbulence of the jet is clearly highlighted by the self-aeration and white waters of the flow.
