there are some very few occurences of previously mentioned

<br>
key incline <br>
The use of incline tag is presently for a fixed difference in height
over some distance. <br>
For tidal flows the incline is not fixed (varies with time, moon
position etc), so I would not use this tag. <br>
It goes against OSM present practice. <br>

The word "oneway" to me imply the direction is one way ONLY. <br>

Flow direction is the best of these (so far). It is descriptive of
what is to be tagged. <br>
It may also be used for other things (carrying anything) .. the tag
should not be restricted to just water ... while that is the common
application .. why restrict it? <br>
