http://onlinemanuals.txdot.gov/txdotmanuals/hyd/velocity_protection_and_control_devices.htm WebThe negative-step stilling basin is an efficient and safe energy dissipator for high-head, large-unit discharge high-dam projects. However, studies of the effects of the negative step on the hydraulic performance of a high-dam stilling basin have not been conclusive. In the present study, a 2D RANS-VOF numerical model was developed to simulate the flow field of a …

Tailwater depth can play a very influential role on where the jump will occur in the channel, and changes in this depth can shift the jump either upstream or downstream. WebThis flow often discharges at a high velocity and must be directed away from the toe of the dam. An energy dissipator is used to retard the fast moving water by creating turbulence and developing a loss through change in the water's momentum. ...
