The ‘dry swamp’ has no apparent way to tag it. These will not be found
in Europe, just as you don’t find deserts there.

They have occasional water, not seasonal, not yearly but, say, between 5
to 20 years they have water. As such they do not satisfy the OSM swamp
definitions at all.

I see few options. If it happens more regularly, map as:

- If it happens more regularly, map as: natural=wetland + intermittent=yes
   there even exist few cases of "wetland=dry", so you may add that (or 
something similar) too.
   
   Yes, I know that "natural=wetland" tag talks about "seasonal", but note the "intermittent=yes" changes the meaning of

   the main tag significantly. There are even things which are normally 
(without intermittent tag) ALWAYS full of water
   (like rivers and lakes), but intermittent=yes changes what they are:
   
   https://wiki.openstreetmap.org/wiki/Key:intermittent
   
- if they very rarely (if ever) become waterlogged, mark them whatever they are currently (or most of the time).


   After all, you wouldn't mark say Fukushima as wetland, because due to its 
location and climate it is prone
   to tsunami and flood disasters.
   
   So, if there are trees, mark as natural=forest. If grass, landcover=grass. If no vegetation then natural=desert. etc.

   Add human readable description=* mentioning the rare floods when it becomes 
swamp.



Some deserts have vegetation. And they are still deserts even with 
vegetation. Some deserts are not sand, and they are still deserts. It is 
not the land cover that make a desert.


Dry/arid/ephemeral swamps are still dry/arid/ephemeral swamps even when 
they are dry. It is not the vegetation alone that makes a 
dry/arid/ephemeral swamp.


   
- see what other similar features in the region use, and copy/paste that.



In one part I have previously tagged one of them, thinking it was a rare 
thing I used a square peg in a round hole... but 4,000 of them in one 
state of Australia, with more of them in other parts of Australia and 
yet more in other parts of the world I think that means there should be 
suitable tags for them not some stop gap tagging.

landuse=meadow should delete the vegetation in the description
leaving the use ... "Used to tag an area of land used for hay
(meadow) or for grazing animals (pasture)." That would make it
clear and possibly reduce its misuse. If you can only see grass
then you don't know if it is a meadow, so don't map that .. but
map the grass!

note that barn storing hay is not landuse=meadow and according to
"land used for hay (meadow)" maybe interpreted in way claiming this.



That problem already exists with the present description, so no change 
there.
