U-bend at upstream end of river by Kanddak

Movie Description:

Somebody crapped up my hydrodynamics education thread by saying that rivers will push water up to the river's original level through U-bends near their upstream ends even when there's available space at the downstream end.
I embarked on a 2x8 site with a stream and dug a U at the upstream end of the stream. The water travelled across 8 region tiles horizontally to go to the downstream end and avoid pathing up.

I know of only 2 things that will cause river water to traverse a U-bend up to its original level:

1. Damming the river downstream of the U-bend - it has nowhere else to go, so it goes thru the bend.
2. Pouring extra water onto the top of the river - pressure will push the water down, causing it to path through the U-bend.

As long as pathing will find any free space without water one z-level under the river - what is technically the case where the river leaves the site - pathing will not go up again to search for tiles on the same z-level as the river.


Do you only see a blank space instead of a play button?
