Actually I think that if you want to make a wholly realistic map, you
should not patch the terrain to match the river, but that you should
use a heightmap both to decide whether there a hills(or even
mountains), and to decide which way rivers flow, and even if there are
inland lakes.

The old generator 1 could be made to work this way, but other
generators don't use heightmaps, so you'd have to rethink e.g. the
island generator so that it both creates islands and uses a heightmap.
It is an interesting task, but not straightforward.
