Good point, but not a show stopper. Wetlands and
forests are mutually exclusive, but real habitat
of a river flowing through a desert or dry bush
looks like the Okavango Delta. It is not a treeless
swamp, but a mosaic habitat. More about Okavango Delta:

In places where the riverbed gradient is low, the
river looks like a narrow, clear lake fringed by
a swamp. Its water level follows the seasons.
In places where the riverbed gradient is high,
the water level is constant and gallery forest
flanks the river. Fine soil particles hold
moisture and extend the width of the gallery
forest. The river becomes muddy.
The early, aquarboreal hominids slept on trees.
Entire family could sleep on one, large tree.
If they walked 20 kilometers a day, they
probably found at least one suitable tree.
If they did not find any suitable tree, they
had a big problem indeed. A very long stretch
of the gallery forest was also bad news because
it was hard to survive on tree fruits alone.
Mountain streams were also good habitats for the
wading hominids. The water was clear and
parasites were less common than in stagnant
water. There was great abundance of stones, so
a stone throwing hominid could not run out of
ammunition. Mollusks and crustaceans were hiding
under the stones.
because their water is clear and their
numerous stones hide
