[Tagging] Drain vs ditch

[Eugene Podshivalov]

Canals and ditches are artificial channels carrying naturual water, so are
the channels of a straightened river or stream. imho there is not
difference between them.
If we had such sections tagged as artificial waterways it would be possible
to calculate statistics on man's impact on natural waterways and detect the
old natural channels.
Considering narrow river sections are tagged as waterway=stream, and wide
streams are tagged as waterway=river, it is only waterway relations which
let you actually understand what that waterway is.

Cheers,
Eugene
