City at a River Confluence - early WIP

[Teh Tarek]

I'm using a simplified version of Ascension's city tutorial to create a city at the confluence of two major rivers (with lots of smaller tributaries).

Feedback would be much appreciated - I can already see that the docks are out of scale!

I think the main channel would normally grow slightly wider downstream after the confluences, due to increased volume. But not always, like if the river grows deeper and swifter after all the merging.
