Description
In the case of low relative drop height (ratio of abrupt drop height to supercritical depth above the drop), a wave type flow is formed for a large downstream depth. The hydraulic condition for the formation of the wave type flow has been clarified in the Journal of Hydraulic Research, IAHR (Ohtsu and Yasuda 1991). The experiment was conducted in Environmental Hydraulic Laboratory of Nihon University (College of Science and Technology).
