Can you stop a tsunami WITH A TSUNAMI in Cities Skylines?

We're back in Cities Skylines (City Skyline) engineering a way to stop a huge tsunami from wiping out my city! We'll be testing some myths including whether a tsunami can stop a tsunami, whether a forest fire can stop a tsunami and whether underwater defenses can stop a tsunami!

I'm assuming the water physics are simulated in cells, then interpolated. Some sections of the walls are thinner than the cell size is wide/deep.

[@ruichikawa]

The Physics in the game is quite good, actually if you send a pulse in the opposite direction it will sum with the other (constructive interference)... so that explains why the wave got "taller" between the walls. Also the "ripples" where the boat was travelling were caused by diffraction, when a plane wave passes through a "slit" and diffracts forming circular waves...

Myth: hexagonal cities would be the best city layout for optimal traffic efficiency and services coverage.

[@argenteus8314]

The problem with that is that you would need to turn at every single intersection. A triangular grid would work better, since you get straight lines back, though then you have to deal with six way intersections...

[@neirenoir]

@@argenteus8314 from a real life perspective, a hexagon-based city with roundabouts in every vertex would probably be a nightmare to drive around, but the NPC of CitySim games seem not to care about mundane things like confusing GPS directions or G-forces. Still, a triangle-based or split-hexagon pattern would also be interesting to explore.

[@michaelr2604]

@@argenteus8314 That is not a problem it is a solution. Turns regulate speed. And with a well planned system of one way roads you could even eliminate traffic lights.

[@argenteus8314]

@@michaelr2604 Still sounds incredibly annoying. I mean, maybe in the densest part of a city where you don't need to cross super long distances, but I certainly wouldn't want the whole world to be covered in a hexagonal grid (which wouldn't actually even be possible, since hexagons don't tile the sphere, but still, if you're gonna consider something at all you should be considering the most extreme form thereof, an actual good idea should work on any scale). If we're gonna have cars at all, then we're clearly already saying convenience is more important than safety, so if that's the case, we'd better go all out in whatever direction we choose. Either design a system that's safe for humans to navigate around(ie, walkable, car free cities) or a system that's efficient and convenient for cars, you can't have both, trying to compromise between two goals is always going to be worse from the perspective of either goal.

[@neirenoir]

@@argenteus8314 as you said before, hexagons are actually just a bunch of triangles. The seams between hexagons in a sphere (mind you that I highly doubt we will ever cover 100% of Earth with anything) could be bridged with triangles to end up having essentially an icosphere.

[@kakhakheviashvili6365]

Fun fact about water sources, they serve double purpose, they not only spawn water, they also slurp the excess. For example, if water reaches the limit (shown as white line while placing water source) water source will take that water in to not create overflow. If you look closely, oceans in this game have big water sources on the far end of the map to take excess water from higher and smaller water sources (like rivers). So placing many water sources on bottom serves basically no purpose for tests like in your video

[@1FatLittleMonkey]

So water sources in the right place, and at the correct level, should stop the tsunami?

[@kakhakheviashvili6365]

@@1FatLittleMonkey If you spam it, maybe. It has a speed on which it "consumes". I haven't played much with them yet, mostly to speed up filling of mega dams, but i think water source produces and consumes water at the same speed. May be wrong though. Never experimented with them extensively.

Could you try to capture the tsunami in an elevated reservoir and use it to generate hydroelectric power over time?

[@williamhopp3024]

You should be able to fix pretty much all of your troubles with water clipping, by making the (terrain) walls thicker. It has to do with the 'resolution' of the terrain, which is only a mesh made of floating coordinate points. It seems that a certain number of points (thickness) are needed for the water to be able to interact and collide with the terrain. I'm not sure how much the water likes 90° vertical angles, but I'd imagine that it too can produce some strange results.

[@jamesfrankiewicz5768]

A couple more tsunami "stopping" ideas for you: 1. You could borrow a landform something like the poo-cano / architectville from your Engitopia city, then bust a hole in the side the entire height. Try to make the flash flood as madly tall as possible at the very beginning. Make sure you put some constraining walls in this one, too. Heck it might even be a nice bonus to see the brown water got up against the blue water. 2. Examine how far the tsunami normally sucks out the shoreline, put in an artificial reef just barely in front of that line. Make sure there are small cuts in the reef (perpendicular to the shore) so it mostly finishes draining just before the tsunami hits the reef.

[@proftuna43]

Hey, I am studying waves at the moment and I had an idea: could you use a polariser to stop a wave? As your tsunami moves up and down (vertically) you could use horizontal bars as a polarising filter that would not let any water through.

[@kgmarcussen]

Try creating highways or very wide lane roads. They will run perpendicular to the tsunami. Each one instantly dips one level, then to the second level and terminates. Thus creating a small dry cave. Do this for the entire width of your shoreline, then copy and paste with each subsequent row. On your last set of cave tunnel roads before your city, have those highways extend as far as possible to give more cave volume. You could build it so that you have a final set at negative 2 and another final set at negative 1 running the full length of the map. Another myth I’d like you to try is to use said highway tunnels to reroute rivers underground.

water in city skyline acts way closer to light, probably because it's way less taxing to render "light" and texture it like water rather than rendering actual fluid dynamics.

[@monad_tcp]

@@ledocteur7701 its because its rendered like a 2D surface, there are two kinds of waves, longitudinal waves and transverse waves. Water is transverse wave, but its modeled as longitudinal wave like light then mapped to height like a longitudinal wave, its a trick. Because a transverse wave would required you to model 3D vectors instead of 2D vectors, it would be much more taxing on the physics GPU.

try building your "walls" using the flood walls on flat ground and then use the move it mod to raise the walls up, think if i remember right, they only reach a certain height before ground starts appearing underneath them but might work better than just building soil walls and they'll be neater.

[@fadikafode4943]

If you modify terrain during pause, the game need some time to update to the new terrain once time is on. That's why water is leaking trough the wall. Or your water sources are too close to the wall (nearly inside)

[@mauropinto1277]

So here's my 2 hypothesis to water just going through walls: 1: when the game checks for water movement it might check for an area, so if the wall is too short the game wont detect, so you'd need thicker walls 2: the game checks for the slope every x space to ckeck if the water is hitting a wall ot sth, so it might be like "so in position x the slope is 0, keep going. in position x+1 the slant is 0, keep going" while at x+0.5 it's completely vertical, but the game misses that. And that would be why vertical stuff has problems in this game (like almost vertical waves being practically invisible from the side and stuff)

[@BetaTestingUrGf]

the water spots, are not just spawners, they also suck in water if waterlevel is too high.

[@--_DJ_--]

I never noticed them doing that in all the time I have been messing around with them. It always seems to drain away rather than being removed at the spawn.

[@BetaTestingUrGf]

@@--_DJ_-- let's say you make a river with a water spot at the top. Make the river end at a lake, at much lover elevation. If you only have the water spot at the top, and you don't have anything taking out the water (like water pumps) , it will eventually fill the lake, and flod your city. If you place a waterspot in the lake, with the height a bit lower than the bank of the river, it will not flood your city. Many vanilla maps, that have springs in mountains, that end in lakes, and and not i the the ocean have the water spots set up like this.

[@drekfletch]

The trench worked because the mass of water entering and remaining in said trench. Creating an underwater trench would help, because all that water fills the void. However you also made walls, which pushed water up from the sea bed to fall as part of the tsunami.

[@Neverender08]

The tony hawk edit with the special move sound effect got me xD respect

[@un7ucky]

You might be able to make one by making a hole, filling it with water, then raising the ground up while the game is running

[@welkiesshitpost7156]

For thr first bit with using water to stop the tsunami, you've experienced destructive interference. Even though both waves will even out after contacting, they will both spring up afterwords. It's similar to how newton's cradle works.

What would a meteor do to a tsunami as it reaches the beach?

[@hyankabeer5840]

16:06 Nope, the trench already filled with water before the tsunami even got there 🤣🤣

[@Big_Max41]

In the real world, I think the two tsunamis colliding would be pretty similar to this. The water in a tsunami isn’t actually traveling at the speed of the wave. It’s the wave traveling through the water. When two waves “hit” each other its not water running into other water. it’s where the elevated section of two waves line up. That just causes the water to rise twice as high (constructive interference). The setup you have here might be different though because you have an actual stream of water moving and it could cancel out momentum in the other direction.

[@ShinichiroKururugi]

I dont know if this has been suggested yet, but maybe you should try defeating a tsunami with other natural disasters in a "Who is the strongest natural disaster!" tournament.

[@jumpingpiggie422]

@16:36 "You can't control the sea". The Dutch: "Hold my Deltaworks..."

[@rebeccachambers4701]

Well when you make a trench to slow down a tidal wave essentially what you're doing is you're re moving Mass. Essentially friction that could help slow it down you know by having less of a floor for it to come in contact with you have less friction that would slow it down

In theory, this WOULD work, provided the defensive waves had enough mass (?) behind them, but this game doesn't have the most accurate water physics

i dont think this would work in theory, in physics, waves normally just pass eachother, amplifying eachother when two peaks meet

[@blacksarlacc91]

@@BetaTestingUrGf exactly what I wanted to write. Wave do not interfere with each other. They travel through each other without any change. Depending on the location this can lead to: both going down = deep drop Both going up = huge wave One going up one going down=nothing (or less depending on whether both had the same size to begin with) The effect is called superposition (of waves; if you Google it because otherwise Google will think you want to know something about quantum physics as those states are described as wave functions as well hence showing superposition)
