Abstract: Plunge pool scour involves a significant risk with trajectory spillways because of structural undermining at a dam foot or destabilization of adjacent valley slopes. An experimental program towards the understanding of ...

Abstract: Bottom racks are a standard hydraulic structure used as intakes in mountainous regions, to divert water to turbines, and to retain sediment and other solid matter larger than rack spacing. These racks are also used for ...

Abstract: The upstream reach of stepped spillway flows may become prone to cavitation damage for large specific discharges because of the absence of air close to its bottom, until the point of bottom self-aeration is reached. This ...

Abstract: To protect hydraulic structures such as spillways, chutes, and bottom outlets against cavitation damage, air is normally added by means of aerators in regions where the cavitation number falls below a critical value. ...

Abstract: Ski jumps are a major element of each dam spillway because these are the only structures able to accomplish satisfactory energy dissipation for takeoff velocities in excess of some

Abstract: Scour downstream of ski jumps may be avoided by jet deflection to an area where the energy dissipation is accomplished. The main purpose of this experimental study was the analysis of the jet air entrainment downstream of ...

Abstract: The current discharge measurement methods in rivers are known to be accurate for low and mean discharges, but large debris and high velocities prevent the use of these conventional methods during flood season. Therefore, ...

Abstract: Ski jumps are a standard element of dam spillways for an efficient energy dissipation if takeoff velocities are large, and stilling basins cannot be applied. This laboratory study investigates the hydraulic performance of ...
