Clarification: I'm meant a route relation for the whole canal, not just
to define travel direction.

I would expect that the situation where the flow direction conflicts
with the traffic direction is likely to be quite short - under
bridges, around obstacles etc. In these cases we could always call on
our old friend "oneway=-1" or "oneway=reverse" to mean "traffic
direction is opposite to the flow direction". Having to create a route
relation is a bit of a sledgehammer to crack a nut.

I've seen it used on navigable canals to indicate traffic direction.
If there is a route relation I think it should be indicate with
forward/backward roles.
If not then for clarity, maybe something like traffic_flow=backwards?
Adding a route relation would be preferable though.

I've certainly used "oneway=yes" on inland waterways to document
signed traffic flow control, so a blanket removal would make no sense.
There may be places where a previous mapper has tried to use it in
error to indicate water flow direction, but you'd need to ask
whoever the previous mapper was in each case (or use a bit of common
sense).

*Subject: *[Tagging] Use of oneway=yes on waterways
Hi
According to the waterway=stream wiki page
(http://wiki.openstreetmap.org/wiki/Tag:waterway%3Dstream):
/If a flow exists, the direction of the way must be downstream
(i.e. the way direction follows the flow)/
As of today there is a very small percentage of streams (17593 ways
according to taginfo, 0.23%) with oneway=yes.
Is there any undocumented purpose? Is it ok and safe to delete
oneway=yes tags for streams?
The same question can apply to drains, ditches, canals...
Yours,
