Abstract: 

The control of hydraulic jump through thin-crested sills in a trapezoidal channel was studied theoretically as well as experimentally. The experiments were conducted in a specially designed stilling basin for 1:1 side slope. The results show that for a given side slope, end sill increases the stability of the jump within the stilling basin. It also causes a 13-15 percent reduction in the length of jump and negligible changes of the sequent depth as compared with the jumps occurring in a trapezoidal section with no sill. Finally, a relationship has been proposed for the design of the height and for the location of the sill to control the jump for a wide range of conditions.
