Can a Tesla Valve stop a MEGA TSUNAMI in Cities Skylines?
Tesla, one of the main people responsible for the invention of electricity and thus responsible for many modern devices such as hair curlers, selfie toasters and secret microphones for phone calls, was not only his name as the inspiration for one of the fastest growing car manufacturers of all time, I'm also pretty Responsible for letting you see this video too, but did you know he also covered one of the cornerstones of fluid mechanics in civil engineering? Well, today we're going to be looking at one of his inventions, and we're going to put it to the test to see if it can
tsunami from devastating a city.
Yes hi fellow engineers and welcome to the city
skylines and today we are not in engiotopia no we are back on this
tsunami map so we have a big area up here that is undeveloped at the moment we have the sea, and then there's a
tsunami coming back here heading towards it, but first you might be wondering what we invented If you might have heard the word
valve before you can
stop water with these
valves there is it like a globe
valve, glow fan, needle
valve, bubbler, there are many different
valves and so on they have moving parts which means they are not too reliable.
They will break down over time. They could be serviceable moving parts and I want to try and test that today but with a
tsunami of such magnitude so the first thing I'm going to do is literally commit some sacrilege. I'm going to erase this bridge even though there's a trade on it Sorry mate you're going to get in trouble but yes I want the whole railroad track gone yes cuz I need to build a levee defense so I will first coming into this tool, the landscape and disaster tool, we're going to use the flat terrain tool, we're going to click this button, so it's a big brush.
We're going to double click on it so the brush is very strong and basically we're just going to draw a straight line across the entire shoreline but real quick I want to thank everyone for watching commenting on the
tsunami videos, which actually made it into the trending videos list on youtube which is crazy and as a little celebration you can now get 10 off everything in my merchandise shop at realcivilengineer.store with the code
tsunami so grab a bridge revision and You're fully qualified to check bridges anyway. Let's get back to defense against the
tsunami. Trouble is, when you get to that end, you'll see there's a river here.
I think there's such a thing as a water sport all up here so if I cut that off I think the water is just going to come down and flood the town anyway so what I have to do I have to put a little gap in my wall let annoying uh but i think that should be fine that sh i would allow this whole area to stay reasonably dry which i will do now. I'm just going to save the game, we're going to call it rio, everything to Mr.
Tesla, and then we're just going to press play, we're going to let the
tsunami wave hit here, hopefully we can see that we're at the right height So here, although I want most of the waves to
stop, um, we want some kind of river
tsunami, so if we just continue this wall, but we're going up, I don't know exactly how far we're supposed to go, I think I'm going to do something like this to start off well, then at the bottom of my screen you can see the water is disappearing because the
tsunami wave is almost there, you can see our wall is actually much higher so it might be ok but yeah before that hits i'm actually going to tear down the wall here if we just grab the level below we should just be able to ah there we cut the wall away and then i hope to see how the
tsunami wave from this vertical wall n being pushed back, but then the main wave continues up there, and if all goes according to plan, we're going to build a city there at the end of that canal, and that's what we're going to defend against, so the
tsunami's about to go, you can see the water being pushed up, hopefully it won't overflow the top when it does or it's just about to transition to the top we may need to add a very small amount of height because yes we have, we have some water over there we don't want that but in the middle you can see it's continuing very far and this is the
tsunami that unfortunately we want to
stop with this
valve design we can't really
stop a whole
tsunami wave, but we can
stop the value of a little little channel so i added a bit more height.
I added the thing there which I will do now. I will expand in this way. I think we're going to want that really far. I will g o want to end those who are wondering who Jelly FX is. I think this is the mod. Thank you for making this map. I'm going to have a kind of
tsunami map, railroads a bit, so let's pack that. We'll hit delete. Oh no, look at all these cars, yeah, we're going to extend these flood walls all the way up and basically we're just creating a giant canal, because the
valve thing that's doing it, it takes up space, it's not like a normal
valve where there are no space issues, it takes time to work and what I could do would be some kind of circular area where we can put the city together now which I want to do just because I'm like that, like I'm an engineer and I say I want to make this structure obvious.
That 90 degree bend isn't going to be very structurally sound like little buttresses, so in real life we use these like they do all the time. Not only does it help absorb the impact, so yeah I think , that's pretty much all set up so we can get our town, and the end of it, I think we could call that the top, yeah, and then we should all be good, right, so we've got some roads inside, I have to connect that to these main highways, and then I don't know if I can tunnel through. I suppose I can be intrigued by what that's going to do.
It doesn't really wait, it tunnels in, but it lifts it, that's random, okay, whatever, so we hooked that up, we're putting that into the opposite direction, alright, so that's how it's sorted. I'll probably do the same with the train line, but I guess that means we're going to need a train station in here, so we're going to plug that in there and go back there by doing an elevated tunnel. I don't know, I don't know what the game is trying to do there, if I'm being honest that's when we get to this page and then we connect there.
Jobs are sleazy d and we have connections from the outside world to our town, which means we can just build some little things here, there's a little, there's a little, alright, so now we have a town and you can see it build itself nice there so i guess let's go back and then this is the first phase of the test. I think we've engineered enough engineering to know that these walls will deflect most of the
tsunami and then the rest will go up here and should be destroyed Our city, uh, sorry, folks moving in, let's speed up the wave and see her progress so hopefully we should see deflections on both sides boosh and boosh nice and then we made it high enough that no water comes over the top oh god oh god we had on this one Side a little spill and by now we have the main
tsunami wave going up the shaft as you can see our town is definitely the target for this thing so you can see it as we watch from above the
tsunami is slowly making its way down above, luckily the meds did a nice little time-lapse so you don't have to wait as long as I'm not lying, although I'm quite intrigued to find out what's going to happen to whom n it reaches the end right we're almost there so let's zoom down here and see oh the wave the wave has definitely shrunk so it's going to go in that's probably going to destroy most things am quite intrigued too see what she's going to do with those tall buildings, are they going to survive the bear game, which is engineering at it's finest, um, but most of the other buildings are completely destroyed so quickly, I'm taking a break because I'm a kid, I just wanted this in the end make sorry sorry everyone but you can kind of see the destruction that is with us without
valves no nothing uh it's not a mess it's an absolute mess so before we actually build the
valve let's do some other ones Do things because we're going to do a bit of technique in this one.
Yeah I can only apologize but you may or may not learn something Okay so I just started a previous save where the
tsunami is up here and what I want to show you is some fluid engineering stuff so have it we basically saw the water flow right to left along the stripe channel that we have. If we imagine this wave going right to left, we basically know it came out like a constant speed because there was no change in the side walls there, everything is just a straight line. So if we imagine this speed if we add something like that it means the water on this side is being pushed through this funnel and basically in real physics if water is coming this way it would be squeezed, and of course when it's squished it's going to accelerate like that If you think about the wave coming this way it's going to go at a certain speed and then as it narrows it's going to get faster and faster and get pushed through there which means that the wave on the right should be a lot slower than the wave on the left, now I feel like the physics of this game doesn't really simulate water, um, but let's do a little test and see if that , what we expect will happen so you can see The tidal wave somehow made it this far, we'll see hopefully it will speed up when the simulation is correct.
I mean the water is obviously getting narrower. Does that mean it's getting higher than where you can see it's getting higher? I'm actually quite intrigued by what the game is doing here, so it bursts through at the end and doesn't look like it's going any faster , it's just gotten bigger but the water still comes out at the end I feel like it's definitely not moving faster, it's about the same, although that's actually kind of like all water bodies disappearing that that would do Make the water worse on this side and make it faster. So if you're trying to craft a
valve when trying to protect your city, this is the wrong way to go.
What if we did the opposite? I reloaded the path of the waves to get there again. So if you imagine the tidal wave coming down here this time you can see it's getting stuck in the corners which isn't ideal and any water coming through there because it's getting wider you think last time that Water getting narrower, speeding up as it comes that direction, and getting wider, the speed will now slow down because it's like the water, instead of going straight it will spread sideways because it's the path of least resistance picks up so it also gets slower and slower as it spreads out and in some cases like in those top corners the water might actually make a full loop and actually go back in that direction and we'll watch to see like c The water physics of the city skyline actually picks this up.
I assume it will do literally nothing from last time. I imagine the speed will stay the same, but presumably the tidal wave will get smaller and it'll behave like a curved wave, which is kind of we'll see what happens here, so we'll see what happens here, so the tidal waves go through the middle as expected, the ones at the edges should be pushed back, and then this one coming through the middle, you see it's getting wider, it's also getting lower, which is exactly what we expected, but that should affect the speed it should slow down and I'm not sure if it will, but yes, in terms of speed, because we have this one down here, which obviously we haven't really affected.
You can see where that is on the line so unfortunately the top hasn't slowed down like it should have but at least it's lower which is a good thing I think where does that stand in relation to that now
valve, now actually using the
valve This principle is particularly where the water was spinning there, and essentially
