  • We're back in Cities Skylines (City Skyline) engineering a way to stop a huge tsunami from wiping out my city WITHOUT using the super mega pumps from last time. Can I put my real life drainage knowledge into practice to build an unfloodable city that can withstand a tsunami? The five step process all real engineers use is in place once again!

      @theGhostWolfe well done. I never found the actual dam-stopping bit difficult, myself. It was just doing it quickly enough in order to have enough time left to boost the population up to those crazy numbers in the really tight time limit, that got me a few times. For the dam-stopping bit my dam never even got destroyed - I made enough of a deep trench sideways toward the sea, that the water never spilled over. That was on my winning attempt, anyway (it took a few attempts).
      Back then I still wasn't crazy good at the game or anything, but that challenge didn't make me good, it just taught me how to pause a lot and make a stupid amount of dystopian population grids on hills. Reminded me of way back when I played Lemmings - a lot of those levels would boil down more to pausing time challenges than actual puzzles.
      I could do it a bit easier nowadays. I didn't know then that plonking down a primary school helped people want to move in to an area more than other services... but what would've really helped me would've been the technique of massively ramping up taxes only to then let them recover in a sort of "tax wave" strategy. Starve and cut it off just before disaster, then repeat as soon as possible. I kept running out of road building money and that would've helped loads.
      I also could've done better with the road types. Lots of the time all you need is dirt roads leading off from a highway. Much cheaper to build and cheaper to maintain. And so long as your only goal is population boom, who cares how unhappy or unsafe anyone is in the meantime.
      In general I found the challenges without artificial time limits more fun. Those you could just take however long you needed at and it seemed more of a natural game flow than just worrying over busting the bank account all the time. More fun when it was more about figuring out what to do. But that was my opinion anyway.
      Like I said, well done. In my opinion it's at least ten times more difficult than any other challenge in the game.

      @Jane Ross ​ I did By the Dam on console last week. I saved up a bunch of money and, after the meteor destroyed the dam, I paused and rebuilt it. It trapped most of the water before it could come down on the city, and flood walls along the river weakened the waves enough that almost no destruction occurred (though it took a long time for all that water to drain). It never produced power, but that’s not what I needed it for.

    I'm pretty sure there's no friction in this game's engine, that's why water doesn't slow down when it moves through flat land. The 45° wall actually should work better then just a straight one, but there's no friction so water slow down because it transfers kinetic energy into potential energy, but the overall energy in the whole wave is still the same, so when water finally is able to get through the wall it changes the potential energy into kinetic. Of course some of the water isn't able to get through, because it's kinetic energy is too small. It's probably water which is behind the extremum of the wave because there's less water giving it kickback energy (it's not pushed by anything) that's why only half of the water get's through when the wall is the size of the wave. Normally some of the energy would go into soil, packing it tighter, heating it, even into the sound the crashes make etc. and some water would sap into it earth, so the waves wight would get smaller and smaller, so overall energy in the wave system would decrease and another systems would gain same amount of energy.

    Working with these frictionless water physics, I think the best design would be a straight wall with a trench behind it. When the water flows over the wall, it will fill up the trench.

    It looks like the game uses a simple friction-less and turbulence-less model for water. So the only thing that matters is the height of the dam (which should be high enough to be able to contain all the water wave's kinetic energy in potential energy (when the water goes up at the dam)).

    • Lekhaka Ananta
      Lekhaka Ananta Bulan Yang lalu +6

      @Konstantin Avilov But you do see that in experiments with walls, there is clearly some volume of water deflected backwards. So a series of shorter walls should in total be able to deflect as much as a higher wall.
      To test this we would need to try placing the series of walls with larger distances between them. I think the resolution of the water physics simulation is so low that the walls near each other don't deflect as separate walls but as a single short wall, hence it not working as well as a single tall wall.

      @Konstantin Avilov Yeah, I think it's nothing more than just a "really deep ditch" that would become useless once it fills with water. It's just that it would be a high-altitude ditch.

    • Konstantin Avilov
      Konstantin Avilov Bulan Yang lalu +7

      @HansLemurson I don't think low walls would work: canals + very low walls practically did not work (see 12:30). Ditches or "inter-wall ditches" large enough to "swallow" all the available water volume may work, but it is a one-time solution, not a universal wave deflector - so it is a kind of cheating...

    • HansLemurson
      HansLemurson Bulan Yang lalu +5

      I think a series of walls where each one can take a "slice" off of the wave height that overtops it should probably work. How is that different than his canals? Umm...

    I remember watching a video demonstration wave reduction and pure vertical wall is one of the worst options due to the wave crashing, going up, and the forward momentum carrying a lot of spillage over top the wall. The 45 was better due to the under wave crashing earlier and lowering the momentum of the total wave. The best, as you mentioned, was the c wall. However I’d like to have seen a Dong shaped retaining wall… And I can only trust one man for the job. You up for it?

    How those power plants work: Basically the sun heats up the area bellow the mirrors, the hot air is lighter and tries to escape. It can only escape through the pipe in the center. In this pipe are wind turbines.

      @Benjamin Brooks it not mirror, it window, it is basically a greenhouse. there is no lens or reflection involve, the idea is to let the heat enter and heat up the air that is trap under it. if you pain it black, the roof would be heated, not the air, it requires the heat to reach the ground, heat up the ground and hence the air under the roof. if the roof is heated up, the air above the roof would heat up and that would put air away from the system then into it. it basically a play on air pressure, you want the air pressure low so it suck cold air in from the side and pushes hot air up from the center. if the air is of the same temperature on both side of the roof, it would not be effective.

    "A lot" of electricity is a matter of perspective. Demand at once? Yes...a lot! Overall demand, start to finish of a tsunami? Not all that much. The key might be in trying two things: An emergency energy storage pack that stays a maximum charge to be released as supplemental power AND....
    The wave...is pretty powerful! We have the ability to capture normal tidal wave energy so it seems logical we could develop tech to capture this...using the energy of the wave against it?!?

  • NFSHeld
    NFSHeld Bulan Yang lalu +1

    In this game, the counter-physically-intuitive method that is a wall straight up is the best solution, because water in this game only has 2 properties: height over ground and speed over ground. Water goes from higher to lower, speeding up, and slow water next to fast water tend to level their speed. But "friction" with riverbeds etc. is not really a thing as you can see at 2:14 - the water at the riverbanks should be slower but it really isn't or if any then just barely at all.
    Therefore, the best way to deflect a wave is a steep wall because that will decelerate the most and introduce a backwards current.

    Seeing that the game basically just subtracts the dam's height from the wave's height, and trenches don't work at all, what you really needed to do was to build two half height dams, spaced out, to get the same effect as you did with your full height one, and make it long enough so the side waves don't reach your city. Still, your struggle *was* at least entertaining.

Like when you were talking about different methods of slowing down water in your real life job, like with the ripples (9:00) or plunge pools (10:40), that stuff really interests me.
    I have 2 years of high school left, attending a trade school for half the day and regular school for the other half. At that trade school I am in a class called Engineering Design technologies, where we’re taught both engineering and architecture. This past year, my first year at this trade school, we got to make our own model bridges using balsa wood sticks and see how much weight they could hold. I believe the weight limit was something like 15-20 ounces or grams, I can’t remember exactly which it was but it wasn’t a lot of weight. And it couldn’t be bigger than like a foot and a half long, and half a foot tall. Including me, there were 9 students in my class. Once we made our bridges, we put a block ontop of them, with a bucket hanging underneath the bridge. We then filled up the buckets with sand until they collapsed, then weighed the sand.
    Using stuff I’ve been taught by you in Polybridge and by other people, I was able to get 1st place out of all 9 of us, my bridge holding something like 8,000 grams. I don’t remember the exact number, but I do remember the bucket being about half full and making a very solid *thud* noise when my bridge finally broke and the bucket hit the ground. I already knew what the bridges weakness would be before I even tested it, and sure enough, when it broke, that exact weakness was what caused it. (I built each side of the bridge in 3 parts, then glued those three parts together, so it was like glueing 2 boards together, and that being the only thing keeping them together) So this coming year, if we do it again, I would like to strengthen that up a little and add a curved support piece on the outside sides, since that wouldn’t add much weight at all and I feel like it’d strengthen it a lot.
    TLDR; Had a bridge building competition in a trade school I go to, I got 1st out of all the other students in my class with my bridge holding about 8,000 grams before it collapsed. I knew the bridges weakness before I even tested it, and my assumption there turned out to be true. I can thank RCE for a lot of the stuff I learned going into building that bridge.
    (My teacher also made a bridge of his own and tried it, his was able to hold about 1,000 grams more than mine, but he’s been doing this for years, so I still think I did pretty good)

    I'm wilded out by the fact that I regularly follow valid engineering decisions when I play Cities, including strongest shapes tucked subtly into the streets and maps.

    I think in this game water physics are quite "linear"
    A series of walls will work pretty much exactly the same as a bunch of bumps, though bumps let the water drain after
    When presented with a perpendicular wall, a tsunami will act ignoring momentum from the middle hitting the splitter

      @Iván Hernández - Entenuki easy solution, put it at the end.
      Plus despite the wonky fluid dynamics, the wave should slosh between the walls, and possibly get positive interference.

      The comment I was looking for.
      Flood barriers pretty much reduce the wave height by the height of the barrier. Using the terrain tool to build a few barriers with sizes comparable to the first one should work while being much more compact.

    Love that your anti tsunami wall ends up looking more like a 17th century Vauban-style fortification. If CS ever do a war DLC then I say you already got it covered.

    Congratz, this is pretty awesome. Could you a few deflective V-walls behind eachother the next time? I'm wondering if that would help at all.

    I wonder if there will be a building engineer game where it has years of wear and tear physics as well as other damage. Similar to bridge builder but about an entire structure. The end level would be a skyscraper or rocket.

    I think extending the deflector both outward and wrapping around behind the city would keep the water from coming in around the sides while still keeping the inland side of the city open for infrastructure

    Do you think putting some trees on the walls/bumps could create some surface friction to slow the water some?

    From the way it works, it would probably be best to just make a series of tall walls. Like, if you noticed how the Tsunami was reduced in height by half in the second wall (Which I think you used as your height limit), then if you just added a second wall it would probably absorb the rest. And since stress isn't an issue, there's no reason that each wall can't be incredibly thin.

    Working with these frictionless water physics, I think the best design would be a straight wall with a trench behind it. When the water flows over the wall, it will fill up the trench

    The anarchy mod brought me an idea of doing those canals extremely close to each other so that they are actually overlapping which means that 1 m³ of space where there are 2 canals will actually hold 2 cubic metres of water.

    Maybe do a lot of pointy concave triangles each individually splitting the wave more and more rather than circles? Like your big splitter but smaller and many times over

    I feel like there is a way to incorporate turbines into the wall structure at the beginning. The water turns the turbines, generating electricity that then powers the pumps

    BTW, you could use my "Terraforming Network Extended (pack)" to draw those simple vertical walls and channels (assuming the physics engine treat that raised terrain the same way). id=2105051034
