Abstract
Many studies have been conducted on the characteristics of hydraulic jump over gradually expanding cross sections, but comparatively few have been carried out on basins with convergent wall. In the present research, the hydraulic jump characteristic of the stilling basin with convergent wall has been investigated. The main objective of this research is evaluation of conjugate depths ratio, jump length and evaluation of hydraulic jump energy loss. According to the charts and results of this study, which are based on measured data, conjugate depth ratio decreases 56 % compared with the vertical case. Also, convergence of the walls along is decreased by 51% of the jump length compared with the classic jump.
