As we have discussed before on this blog, the importance of conditioning and properly transitioning flows into a flume can’t be understated as it can have a dramatic effect on a site’s ability to provide accurate flow data.
Openchannelflow offers a number solutions to properly condition flow – both for new and retrofit construction, including end adapters, wing walls, approach sections, and staged connections.
- Pipe Transitions
- Flat vs. Radius Wing Walls
- Wing Wall Field Report
- Wing Walls for Channels
- Staged Connections
- Flume End Adapter
- Parshall Flume End Adapters

One solution that hasn’t been highlighted is Openchannelflow’s Shaped Transitions for open channels.
Shaped Transitions differ from wing walls in that they typically include a floor as well as vertical transitions.
Additionally, unlike wing walls that are of a single fixed radius / design, Shaped Transitions can either be of a standard design similar to Openchannelflow’s end adapters, or they can be custom to a particular site’s layout. Think of them as end adapters or wing walls on streroids!
