In Oblivion/Fallout 3 the map is divided into a grid, each grid cell is named as such - a "cell". Each cell can have it's own water level and water type (notice rivers are never ANGLED, if they drop they do it via rapids or waterfalls)
My belief that is that they added an additional property to each cell's water - direction and flow speed. This would explain why in bendy rivers sometimes the flow is "off", as the cells arn't especially small and that wouldn't allow much fine tuning. In contrast the smaller "streams" as well as the waterfalls are clearly placeable static scenery and are used to cover the cell-edges where a drop in water level is needed
I would better test the theory on some big rivers but I only got to play skyrim for a couple of days before i had to go travel for a week (typing from my laptop), so I'm current languishing wishing to be home and reunited with my new TES xD
