Take your pick. It would depend on where;
some places have long stretches of road that are 'flood prone', tagged
on the road only?
some places have a short section - a ford. So this would need 2 sections
of stream - one through the culvert (some around me have more than one
pipe so micro mapping would have 3 culverts!) and another section of
stream that intersects the road with ford tagging.
One I just walk past today has a culvert .. that part of the road is
dry, but the road dips down after that and is flooded right now .. depth
~ 0.6 metres length 30? metres. Did not pay much attention to the length.

Would you mind elaborating?
With the stream under a road (way) as tunnel and the default culvert;
The road over the top has either a node or way ford
Or
is the road/way flood_prone yes
Or
is the stream culvert section additionally ford yes
Tnx

Where these are in NSW the DCS Base Map shows where bridges are present.
Some culverts become fords in flood situations, and floods are quite
possible with intermittent waterways so tagging as both a culvert and
food way may be best where this occurs.
Personally I'd leave them alone, other than the obvious bridges they
may not be resolved by imagery alone. I can see them being important
on main roads .. so possibly those should be done.

Hi,
A lot of you may have seen and fixed a node on a road adjacent to
a stream with a single key of fixme="unknown type of water
crossing", what I didn't realise until I ran an overpass query

that there were 2377 of these fixme remaining in Australia and they
were all added by a single organisation.
A lot of these are clearly fords on dry/intermittent creeks and I
can't see the reason for not mapping these as fords instead of
adding the fixme note to limit the amount of editing now required to
fix these imported fixme notes, most from 2018 and 2019.

As the node is adjacent to the stream, I can't see how to easily
edit these where it is clear it is a bridge or predominantly a ford
in an easy process. e,g, https://www.openstreetmap.org/node/6839769585
Any thoughts?
