I'd like to add to this that on a semantic / natural language level,
waterway=riverbank (deliberately ignoring long standing, widespread use and
acceptance) would seem to indicate a riverbank, i.e. the bank of a river,
or in other words, the area along a river, which will occassionally but not
always be flooded.

I am at this point not proposing to remap all of these (unless there would
be compelling agreement by many mappers), as this is a longstanding, very
widespread tag (293.000 occurences, 31.700 of them relations) with
supposedly uniform usage, but it should be noted that there are issues with
it on a logical level.

Cheers,
Martin
