Rivers on procedurally terrain

I have been trying to create a procedurally river system, but I haven't quite figured out a good solution yet.

I could try the standard one with having a water plane at a certain level and then just modify the terrain where I wanted it to. But I want it to be a little more advanced, I want the rivers to run down the sides of my mountains and then become a waterfall if it gets too steep. I have figured the waterfall part out, I just need to find out how to create the river system, and then implement it. I have tried to make a copy of the terrain as a mesh and then make it have my water material, but that didn't quite work out, because it sticks out at random spots and it doesn't quite get me the results that I wanted.

Does anybody have any ideas on what I could do instead?

This sounds like a complex task; A forum thread might be a better place for discussing this. Anyway, you don't give any information about the kind of terrain you are generating, if it's based on Unity's terrain or a custom solution.
