Impact Basin Examples
From ASDSO Dam Safety Toolbox
Energy dissipation in an impact basin is accomplished through the turbulence created by the loss of momentum as flow entering the basin impacts a baffle, and the direction of the flow is changed. At high flow, further dissipation is produced as water builds up behind the baffle to form a highly turbulent backwater zone.
The type VI impact basin is a relatively small structure with highly efficient energy dissipation characteristics. This type of energy dissipation structure does not require tailwater control.
