Reinauer, W. Hager] The wave diffractor is a pyramid-shaped element to reduce shocks originating from wall deflections. The novel element is tested in terms of optimum geometry, and effects of Froude number, among others, and a simple shape is introduced. The device is not susceptible to cavitation because a local aerator can be combined with the wall deflection, and abrasion is also not a concern. Shockwaves can be significantly reduced in height by the device which can also be added to existing chutes. The diffractor is interesting for all locations where the required freeboard due to the shocks becomes excessive and a local device is more economic than an overall increase of the chute side walls.
