To be clear, "oneway=yes" means _traffic_ direction in the direction of 
the way, not _flow_ direction.  In the case of waterways, these can be 
different.

For waterways the _flow_ direction is assumed to be in the direction of 
the way (and yes, this causes issues with some canals and drains).

However as written the wiki page currently says 
"flow_direction=forward/backward/both" - it makes sense to me to avoid 
the word "oneway" to avoid confusion.

Cheers,

Andy
