I guess that there are going to be times where you have to chose between building on a river for additional buildings and building next to a mountain so you can build an observatory
I don't know about tile yields but right away I can think of windmills (10% production towards other buildings) and hydroelectric damns (+1 production for every tile of river in the cities radius).
I try to build on the river for the damns mostly.
River cities are definitely a must because of windmills and other improvement bonuses.
Windmills are just on flat terrain, not rivers. Dams yes and also Watermills. I think those are the only two but they are a couple of big ones.
I think you mean watermills.
I was about to mention the fresh water, but civ5 doesn't have a health system! If you have abased economy (heavy on the trading posts/lux resource tile working) it might be better to settle 1 tile away from rivers to make way for the 4
that comes much earlier with CivServ farms (earlier than fertilizer-based farms) and then the extra
from a trading post. After all, it takes a bunch of hammers to build a watermill for the 2
1
boost. I'd rather get a quick
boost from farm and then
to purchase buildings/units.
Here's what you want:

Avoid a plains tile if you have a lot of stone about. For some reason stoneworks cannot be built in a plains city.
