Answer

It's mostly a stylistic choice based on how each word sounds.

Answer

I would use 'to run' for water, and 'to flow'  or 'to go' for rivers and alikes.
Using 'to run' for a river will emphasize something. 
Only the Author  knows whether there is some meaning to be emphasized.

Answer

Have you ever heard this song: The ballad of Easy Rider ?
First lines run like this:

The river flows
It flows to the sea
Wherever that river goes
That's where I want to be
Flow river flow
Let your waters wash down
Take me from this road
To some other town
... ...
