Impact Basin Examples
From ASDSO Dam Safety Toolbox
Message: Examples of a Impact Basins
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.
