Corrugated Metal Pipe

[FLBuff PE]

Has anyone found an in-line energy dissipator in CMP? I have a client that will be redirecting an irrigation ditch from a earthen ditch via a CMP culvert down a steep slope. The client is worried about the velocity of the piped ditch water entering a receiving ditch. I've checked Contech's website, and did not find anything there. Links to specs and drawings would be helpful. Thanks!

Yeah, I had found some flared end sections, but the outlet MIGHT be submerged, so I'm looking for more of an in-line dissipator. I found a patent for an energy dissipator ring, but can't seem to find a manufacturer of one.

Edit: I've also thought about rip rap, but that doesn't make much sense for a submerged outlet.

FL, we've used riprap for submerged outlets here with some sucess.

I also thought of an impact box like some of the western states use. That may only be applicable to low tailwater conditions.

plus riprap, if applied properly does not float arty-smiley-048:

A problem we have here with riprap at outlets is improper installation - not using a filter fabric or sand/gravel filter to keep fines from sucking up from under the rock.
