Dams

[beorn]

I find dams particularly frustrating.

The game rewards planning ahead where districts will be placed, and one of the key factors is placement of dams. But once I have discovered Buttresses, I am often surprised at where the game thinks I should be allowed to build a dam.

Like in this screenshot. Why can Arnhem not build a dam two hexes southwest of the city (tile with "Amu"). Floodplain. River on at least two (actually three) sides of the hex. No other dam on the river. Any explanation?

My guess is that there is actually 2 different rivers there, which DQs it.

 

[criZp]

I assume the lower left edge of the tile has the river wadi, and the two other edges has the river amu, and that's why it doesn't work

 

[Linklite]

Alternatively, does 5hat tile definitely belong to Arnheim? You've built pretty close together. It might belong to Leiden.

I'm certain it's because the floodplain "belongs" to Wadi al-Rummah, and thus floods when Wadi al-Rummah does. But only the southwest edge of that tile borders Wadi al-Rummah; the southeast and east edges border Amu Darya River. So the game says you can't put a dam there because you only have one tile bordering Wadi al-Rummah. I guess you can rationalise it as the floodwaters originating from Wadi al-Rummah's source southwest of the wine tile, so a dam on the tile you're talking about wouldn't intercept it enough to stop it, maybe...? I agree it is janky and unclear tho.

Yup, pretty much my point. Buttresses are the only tech I beeline not because I am so anxious for the tech benefits, but so I can find out how the game is going to interpret the map.

I usually don't get bad surprises with Dams - my personal struggle are the Canal districts. No three-ways, no hills, no cliffs...and I still feel that I miss something sometimes

Canals always seem to be like - here, build me right where you can go around this one tile. I haven't found my "Panama Canal" type usefulness now, and its annoying the game wants one in places it wouldn't even help me to have one.

i don't find the civilopedia description particularly helpful.

Canals really need to be placeable on hills, just with increased production cost. There are plenty of real world examples of canals through hills/mountains. Have it be a bonus unlocked with a later tech if it's deemed too powerful or whatever.

 

[Josephias]

You mean this one, in example

Spoiler :

Yeah, I think there is a case for canals being placed on hills maybe as you say, with increased cost and/or later tech avaiablity.

I can't think of a real-world example of a canal through hills that's capable of taking capital ships.

Spoiler from wikipedia.org/wiki/Culebra_Cut :

The Culebra Cut, formerly called Gaillard Cut, is an artificial valley that cuts through the Continental Divide in Panama. The cut forms part of the Panama Canal, linking Gatun Lake, and thereby the Atlantic Ocean, to the Gulf of Panama and hence the Pacific Ocean. It is 7.8 miles (12.6 km) from the Pedro Miguel lock on the Pacific side to the Chagres River arm of Lake Gatun, with a water level 85 feet (26 m) above sea level.

Construction of the cut was one of the great engineering feats of its time; the immense effort required to complete it was justified by the great significance of the canal to shipping, and in particular the strategic interests of the United States of America.

Culebra is the name for the mountain ridge it cuts through and was also originally applied to the cut itself. From 1915 to 2000 the cut was named Gaillard Cut after US Major David du Bose Gaillard, who had led the excavation. After the canal handover to Panama in 2000, the name was changed back to Culebra. In Spanish the cut is known as the Corte Culebra and is also called the Snake Cut.[1][2]

Well yeah, I've been through Panama and can state first hand it has locks. But the elevation of the surface of Lake Gatun is 26m. That's not much of an ascent, and even that was a huge engineering challenge.

Canals over ranges of hills featuring series of scores of locks don't work on the scale of large warships or freighters.
