When the erosion anticipated downstream of the outlet works is minimal and/or manageable, a plunge basin (pool) is commonly used as the energy dissipator. Plunge basins may be lined or unlined. The discharge into the basin may come from a free outlet or from a valve. The following pictures are examples of plunge basins:
-
Unlined plunge basin (view is looking downstream). This basin has been allowed to scour over time.
-
Concrete-lined plunge basin with baffle wall, grouted riprap side slopes, and discharge channel. Flow discharges into the plunge basin from two 36-inch diameter fixed-cone valve.
-
Plan view of a typical lined plunge basin design.
