Currently we are designing a number of culverts that transverse down some steep banks and required special energy dissipators. An associate from another company put me onto the HEC14 documentation for the design of these.
In reviewing these documents I also found this very helpful series of training videos that refer to the HY-8 software that can be used to design culverts and outlet structures in accordance with HEC14.
1. Open-Channel flow concepts.
2. Grate Inlets
3. Culvert hydraulic concepts
4. Hydraulic effects of culvert liners
5. Aquatic organism passage design concepts
6. Energy dissipators for culverts

Also looking at designing some Hydraulic Dynamic Separators and follow some helpful information on this page.
