I was also thinking about the flood_prone=yes, and intermittent=yes of
Pierre is also a good option, but I don't understand why a ford ceases
to be a ford when the waterway/riverbank is dry. Does it mean that we
can have a ford only when a rivers current is perennial?
Maybe a possibility would be ford=intermittent? I don't know. But if the
waterway/riverbank are tagged as intermittent=yes, I guess we don't need
to say that the ford is intermittent.
Cheers,
Rafael.

I am quite satisfied with this import project and the wiki. It
confirms were the waterways are fTooding. And it is easy with josm to
realign if necessary.
And I dont buy the interpretation that these intermittent waterways
should not be traced because of climate change. We could argument that
climate change exacerbates succession dry periods and violent
floodings. And we did observe that everywhere in the recent years.
These waterways are an important characteristic to add to the map.
Populated places are often at proximity and these waterways are both
used for communications in dry periods and for their water ressource.
This is also an important information to anticipate where major
floodings will have an impact.

Hi Martin,
Thanks for your ideas. Meanwhile I was searching a bit and found the
tag*flood_prone=yes* in the highway-wiki for Africa
https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa.
@Rafael: that would be a could choice for an highway inside a
riverbed. What do you think?
Regards
Arne

Hi Martin,
Any suggestions how to map a highway inside a riverbed? It should
indicate somehow that the highway may be flooded by water occasionally.
Thanks for your remark.

Good.
the wiki states a ford is for crossing a waterway, and this is what
I would expect as well. A highway running inside a (dry or semi-dry)
riverbed rather than crossing it, is not a ford.
Cheers Martin
