It just struck me that the map here is almost a commentary on those water channels that don't follow the "basic" rule of simply going downhill.[[User:Jerodast|- jerodast]] ([[User talk:Jerodast|talk]]) 04:46, 9 October 2023 (UTC)

:I'm pretty sure all those bits of water ''do'' flow downhill (or, at a push, flow along a completely level bed by dint of more water being dumped in at one end whilst the excess is allowed to exit at the other). Just that it's not all the same direction along any particular composite route, with possibly multiple drain/source points wherever directions meet/diverge. And possibly you have to abstract out any lock-gates/similar as continuity even when closed.

:That some of the canals are sent through undulating topography (to be valid here, surely can't involve tunnels/aqueducts; but deep cuttings are a thing... as are channels atop embankments, making only ''slightly'' confusing in this regard if they designed wet or dry culverts under them to maintain the old cross-directional terrain profile) doesn't change the level/downwards gradients in their very local geography.

:The exact details are (deliberately?) lost in this topological-but-not-topographical diagram, however. ;) [[Special:Contributions/172.71.242.122|172.71.242.122]] 13:17, 9 October 2023 (UTC)
