Better use an own tag like flow_direction=forward/backward/both/none or
similar. This way we will cover all three cases mentioned below.
Where is the difference between "flow_direction=forward/backward" and
"oneway=yes" ? or "flow_direction=both" and "oneway=no" ? About
"flow_direction=none", then you water stream/canal/pipe is not a water
stream/pipe/canal (change the primary tag).
The oneway=yes tag is an access restriction, ie which direction you are
legally allowed to travel along that way. Whereas the flow is what
direction the water is physically moving. So it makes sense to use
separate tags for these.
A river may be flowing downstream, but it is usually legal to travel by
boat in the opposite direction. Or a canal has no flow, but boats can
travel in either direction.
