The Silver City (a big city around a waterfall)

[feanaaro]

The niagara falls example is interesting indeed. Because the river widens quite a bit just before the waterfall, although it is previously narrowed by the rough terrain as compared with when it exits from lake Ontario. It is true though that it produces a much bigger pool (technically, a whole lake) after the fall, I will work on that. Also, apparently a 500m wide river produces the niagara falls, so mine much bigger one should perhaps produce even bigger falls? Is there a clear ratio between how big the river is and how wide the falls, given a more or less vertical drop of a given height?

edit: meanwhile..
