I just noticed that the rivers in central Africa first go up and then down. E.g. Lake Albert and Rutanzige to Lake Victoria. They're probably not the only ones.

Anybody ever notice the mashlands around Ethiopia (SW & W Ethiopia, IIRC), that have the 'arid' modifier. What is an arid swamp?
Is this just a graphical thing or related to the terrain? You might want to post in the bug forum if you think it's incorrect.
Arid marshes occur anywhere you have an upstream source of water, usually highlands causing precipitation, and a flat depression (either enclosed or as a coastal plain where it enters the ocean) in an arid region for it to collect in. Lots of examples: the Mesopotamian Marshes in Iraq, marshes along the Lower Nile, around Lake Chad, formerly in the outlet of the Colorado into the Gulf of California. Those are all permanent, and large enough to be province-sized, but there's plenty of small ones too (I think in Tunis, or elsewhere in N. Africa). There's also seasonal features like the Okavango Delta in Botswana.
The one in question is the Sudd in South Sudan along the White Nile. Wikipedia lists rainfall as 55-65 cm (21.6-25.6 in), which isn't all that dry (desert conditions are generally < 10" / 25cm) 55-65 cm is like the US Great Plains, the southern Pampas, Eastern Germany, Poland, the wetter parts of Spain and even London/Eastern England (only 23" a year!).
Of course, rainfall isn't all that matters, there's also evaporation. It seems EU4 uses an aridity index (Precipitation/Potential Evaporation) I'm not sure what the cut-off is, but it might be interesting to try and find out. It looks like some places like Spain, for example, should be arid given that they seem to be the same index as the Horn of Africa region.
That's another good example.
OK, and here I was thinking someone just plastered 'arid' all over the region, with no consideration for marshlands. (which, to my knowledge, would always have been synonymous with 'wetlands') I've lived in swampy regions (provinces?) before, and there was nothing 'arid' about them... lol.
But alas, now I know. How could I have made such an assumption? tsk-tsk
Good answer. But now here's the next question: Who's idea was it to make the Himalayas (et al. mtns) about 500,000ft tall? Or maybe higher... hard to say exactly. Zoom in all the way... you'll see what I mean.
edit: yeah, probably way higher than that. Pretty sure the int'l space station would crash into those mountains.
