[talk-au] 2377 occurrences of fixme="unknown type of water crossing"

[Warin]

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.
