can you edit/create rivers?

[HeyImDashie]

the title is pretty self explanatory lol, is it possible to modify or create more rivers?

Yes! Indeed you can. It's a big feature, where you can alter both the water and cliffs.

Although you cannot move the river mouth, where the ocean connects with the river. They stay in place.
