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.

Ski jump jet in the ski-jump-step energy dissipater
Considering problems like energy dissipation, cavitation and atomization caused by high-speed flows, ski-jump-step
energy dissipater is proposed to provide sufficient aerated flow for the stepped chute downstream through pre-aeration in
the ski jump and aeration basin with large unit discharges, therefore extends the applicability of traditional stepped
chutes in terms of discharge limitations. In order to optimize the flow pattern in the ski jump of the ski-jump-step energy
dissipater for structure design and safety consideration, 3 cases with different geometries were designed and the
classification of flow regime as well as the hydraulic characteristics in this section was experimentally investigated. It is
concluded that the flow pattern in the ski jump can be significantly improved by the arrangement of ventilation shaft as
well as the lengthening of flat bottom tunnel.
