Yes. I think that is exactly the important point and a very good
description/criterion. flood_prone=yes for things that are_not_
designed to be flooded.
No! Flood prone means that they are expected to be flooded from time to
time. Nothing about the design. I'd hope that the flood_prone tag would
be applied to an area, and best if the frequency is noted e.g. once
every 100 years.
And waterway=*, ford=* … for things that_are_
designed/expected to be flooded.
Again no. A ford may be continuously under water. E.G. a road that goes
through a river .. where the river normally flows across the top of the
road. Some fords may only have water in floods, others seasonally, and
others continuously.
