Energy Dissipator
Energy Dissipator
(OP)
Anybody have an example design of a baffled energy dissipator or point me in the right direction to the equation for one? A municipality is requiring that an energy dissipator be constructed at the end of a detention pond outlet. The outlet is a "V-Notch" outlet.

The book can now be downloaded in .pdf format from several sources. IIRC, I downloaded it from the USBR website about 10 years ago, but I can't find it on their site right now.
BTW, we call them "baffled outlets" because calling them "befuddled outlets" is considered politically incorrect.

As long as the velocity was fairly low I didn't do calculations, just added 3 to 5 staggered rows of blocks and spaced them so that they ended where the outlet slope leveled off.
