Thanks for your comments
I changed waterway=riverbank to natural=scree
The map already had 2 river channels indicating a braided stream
I referenced our conversation in the changeset comments.

It is tagged waterway riverbank. Do you have any suggestions
for better tagging?
This should be micro-mapped from aerial images. You need to compare
images from different years to see which parts of the area are
frequently changing, and which are not.
natural=scree seems fine for most oft that area. The green parts are
certainly natural=fell. waterway=riverbank is ok on the area around E
11.6636714 / N 47.0004158, which is covered most of the time by the
varying branches of the stream.
I have never been to that region, but in general the alpine waterways
carry a lot more water in spring and early summer due to snowmelt. You
don't see these water levels in aerial images because they are taken
when the snow is gone. So it's possible that waterway=riverbank is
correct on a bigger area, but then it should be accompanied by
intermittent=yes. See
https://wiki.openstreetmap.org/wiki/Proposed_features/ephemeral for
ideas how to specify the season.
The waterway=stream itself should be adapted to the latest aerial
image. This may by outdated anyway, but it's still better than what is
mapped by now.
