The Characteristics of Disturbance and the Measures of Decrease on Rapid Flow Shoke Wave in Sloping Channel

A series of strong shock waves will be produced when water current passes those special sections,such as constringent section,proliferation section and curved section in discharge structures.And the wave makes the water current asymmetric in transverse distributing of momentum,causes the flow pattern worse,and brings engineering disadvantageous influence.Based on the analysis on the characteristic of disturbance of rapid flow shock wave in sloping channel and some methods of avoiding the shock wave influence and improving flow pattern are introduced,these measures have gotten good results in actual engineering.
