FP McCann have pulled together this little video for us to demonstrate what differing flow rates actually look like.

This doesn’t really change how we design SW systems, but is useful context for something that can be hard to visualise:

For reference they are also looking at including orifice site in their StormBrake spec info in Flow and they can also provide some information relating to how their baffle blocks slow down water flow – which we have previously been requested to evidence by the Canal & River Trust on outfalls.
