IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

The Water-Wings and its Weakening Methods Downstream of the Bottom Discharge Outlets of High Dams
Author : ZHU Yaqin, ZHANG Faxing, XU Weilin, LIU Shanjun and DENG Jun
The water-wings are the specific flowing phenomena which occurred frequently at the discharge structure in hydraulic and hydro-electric engineering project. Some types of water-wings will cause harmful effects on the hydraulic structures or its normal operation. The large scale hydraulic model tests and turbulence numerical simulation technique were employed to investigate the water-wings hydraulic characteristics downstream of the bottom (high-head) discharge outlets with sudden lateral enlargement in a high arc dam. The causes and influence factors of water-wings strength were analyzed. The water-wings weakening methods, such as modifying the layout of the deep discharge outlet, were carried out. A new deep discharge outlet type with upstream planar spread layout was proposed and it can weaken the water-wings strength effectively.
