Is there a way to stop tunnels being flooded near water sources? Discussion

u/SpyChinchilla Sep 07 '24
Pull it way back. IRL a tunnel would never start that close to the shoreline.

The issue with this is that in game I don't believe it's actually flooded. It's just showing water. I just tried and cars drive through like normal despite the water being there

u/Real_Bobsbacon Sep 08 '24
Cars are completely unaffected from flooding, even if it was a normal road on land that got flooded. It's a shame as CS1 has a better feature. Hopefully, they'll bring it back in

u/TheCoordinate Sep 08 '24
oh wow didn't realize that. That defeats the point of flooding

u/Real_Bobsbacon Sep 08 '24
It's actually really frustrating. The water doesn't evaporate like in CS1 nor can you use the water pumps to suck it up. I had a part with a river overflowed onto a road, I couldn't do anything with the part. Only way was to build land up so that the water flowed back into the river.

And there's room for an entire plaza and a helicopter landing pad between the tunnel entrance and the end of that island.

u/thegiantgummybear Sep 07 '24
Why did they even build that island in the middle vs putting the tunnel on the main land?

u/AardvarkAblaze Sep 07 '24
They only need a channel wide enough for ships and tunnels are waaaaaay more expensive than bridges.

u/thegiantgummybear Sep 08 '24
It’s wild that building an artificial island with all the utilities having to run out there is cheaper than a bit more tunnel

u/FellaVentura Sep 07 '24
To be fair that's still nowhere near a shoreline

Thats still 300ft from water, op is 10 feet

Did you ever see the giant shit volcano?
And you want to discuss logical physics in this game?

u/reflect25 Sep 07 '24
That’s also has a wall around it, it’s either dug the tunnel portal father from the shore or build a sea wall but either way don’t let the water level get too close to whatever the tunnel level is

u/OD_Emperor Sep 07 '24
The point being it's a game, tunnels that close to the water do exist whether you have the decor around it or not it should just work. Or be like the water pipes underground where if you try to dig them up you can't.
6
u/reflect25 Sep 07 '24
No the point is if you want to build it that close then you need to build a wall around it then. Even for that example if you actually look at the google street map there’s a wall around it.
No engineer builds a tunnel at let’s a small ocean/river wave let water in
If you don’t want to build a wall then dig the tunnel portal farther away

u/Scheckenhere Sep 07 '24
Almost 400 meters (50 cells) from tunnel entrace to the shoreline. You kidding?
2
u/andres57 Sep 08 '24
Aren't you giving him/her the reason? That tunnel is nowhere so close to the shoreline
2
u/BunchesOfCrunches Upstream Sewage Outlet Sep 08 '24
For real. I think it makes sense for the tunnel to be flooded in this instance.

u/hjvddool Sep 08 '24
Oh here in NL it does

That tunnel clearly starts three road widths away from the shoreline, as opposed to OP's 1/5 road width from the shoreline.

u/Peuxy Sep 07 '24
Those black squares before the building are light shades, they are not the roof.

u/A_wild_so-and-so Sep 07 '24
You should have linked the satellite view, I just looked it up and it makes it much clearer how close the shoreline is.
1
u/BunchesOfCrunches Upstream Sewage Outlet Sep 08 '24
The difference is this tunnel entrance is about equal height with the water
33
u/NoriXa Sep 07 '24
Its the fact tunnel entrances have no real collisions for water to prevent its entry so a decent area around them will allow water to flood from seemingly nowhere move the entrance back or largen the land those are the options.

u/tonybeatle Sep 07 '24
Don’t build so close to the edge? 🤷🏻♂️

the water mechanics in this game is a bit shitty, i had the same problem when using tunels in island
41
u/Megacitiesbuilder Sep 07 '24
Yes I have the same problem, those tunnel opening near water will always have water physics displaying in it, but it actually is not that close to water
6
u/Teddy_Radko vanilla asset guy Sep 07 '24
If i dont misremember all tunnels below sealevel will flood regardless of distance between shore and tunnel entrance

First person mod used on mertro train is really funny because of this.

if you can use mods, maybe use the water resources mod to decrease the water level of the sea?

u/JNKW97 Sep 08 '24
So some of you say not to build so close, though I have tried different tunnel on the other part of the map, it's way further, like 100m and still could see the water.
3
u/Litrebike Sep 08 '24
This is pretty realistic. That tunnel would never get built.
2
u/JNKW97 Sep 08 '24
This one yes, it is only an example. I got a tunnel 100m from water but still flooded.

u/NoesisAndNoema Sep 08 '24
Yes, but not by us. The developers need to create a "clipping void", which they still have failed to create for tunnels.
It requires a shader to be programmed to ignore rendering the water, within the "void". Like a window on a wall, but on the water surface. Basic 3D stuff that they have no clue how to program, because they are using other programmers code and plugins.
They are so limited in what they have an ability to do, due to this same issue. If they actually programmed this stuff, they could fix it. But, they didn't.

u/SirRealBearFace Sep 07 '24
Quays could help. Look at the terra forming tab water section and you'll see it
2
u/DookieToe2 Sep 08 '24
In NYC, they have these huge inflatable plugs that they put in either end of the tunnel. It’s only partially effective, but it’s better than nothing.

u/aero_sock Sep 08 '24
Overall the tunnels are hella infuriating to make. You can't have the shores too steep because then the tunnel just starts becoming overground under the water.
I wish I could use bridges but you can't get shops under them(except for the golden gate Bridge, but its minimal length is like 200m)

u/DaFrenzyGuy Sep 07 '24
Make the tunnel enterance a little more far away from the shore, that way the water doesnt get in, usually. If the sea level rises tho, it might flood again.

u/Conscious-Ticket-259 Sep 08 '24
Might be able to put the waterfront walls. I forgot what they are called

u/GerryBlevins Sep 08 '24
Don’t worry they will still drive thru it. All the cims have James Bond cars.

u/ybetaepsilon Sep 08 '24
From a realistic perspective this flooding makes sense. You would not have a tunnel dug into the ground this close to the water level. Ideally the road would go uphill a bit then dig down

There should be an option somewhere to build a "Quay" of sorts. Kinda like a raised edge to the water source.

Don't? Build a bridge, not only cheaper but also looks nice. Worried about ships passage? Make them higher.

Try building out the land a little at the tunnel opening
