The secret purpose of these holes...

Part 3! Hydrology Engineer is so much more than a game, it is actual drainage engineering software, made accessible (as long as you have $150!) It will teach you how to design real drainage, I should have just played this than spend 10 years learning that I did!

[@rawcus918]

Why can’t you just play this game. All of these episodes you’re just going to explain all the same obvious stuff? Really? Running rain simulators without even hooking the drains up. Why not build it all just guessing since you know it then adjust it. Instead you’re just going cheap as possible from the beginning and it’s so pathetic. I can’t believe you think this job is hard and couldn’t be done by anyone. I bet when you started your first job doing this they trained you as if you knew nothing outside of basic school going over there processs and whatever. Seriously unsubscribing from this channel. If a drain gets blocked then the road has more than usual rain on it? You serious bruv?

[@rawcus918]

I glad I don’t live anywhere where you designed drainage super spaced out drains then three close to each other with wide as possible down the road. I mean how simple can someone be. Don’t script out or think about how to make this cool. Just wing it bro and do the same thing three times in a row. I mean have you even made it to the end of the game to see if less water is left in the roads after you hook the drain pipes up? I can never make it that far but you know what isn’t obvious? Why would the drains pick up all the water when they have no where to go with it yet you can just run the simulator. How does that not need explaining. I mean you’re not giving us a layman’s explanation of how easy drains are to clean are you? You could provide a source to this right or reference personal direct experience on some kind of resume right?

[@RealCivilEngineerGaming]

Just because its obvious to you it doesn't mean it's obvious to everyone and unfortunately you seem to have missed something very obvious in that the surface water simulation and pipe simulations, just like in real life as I mentioned in the video, are separate from each other so hooking up the gullies wouldn't change how they react. I never said this was a hard job that couldn't be done by anyone, just that hardly anyone actually has any experience in doing it- my channel pretty much exists to show that engineers are just normal people as there's definitely some misplaced assumptions about engineers. Also you misquoted me, I said if an upstream gully gets blocked then the downstream one will have more flow going towards it. Anyway I'm sorry this video offended you so much, do us both a favour and go watch something you actually enjoy. Also, since you are clearly craving attention, have a pin! You're welcome! 😊

OH CRAP that thing you said about pipe depth just solved a family mystery! Out of nowhere one day we had a sinkhole appear in our side yard. It was 30 feet deep and 10 feet wide. It looked like a hole in the ground you see get generated in minecraft. Cost us 2 grand to get it filled. We found out that it was because our dry well had collapsed. However I'm looking at the hole and it looked like there was actually places on the wall where water was flowing as if it was part of a stream. The thing is that the pipe that fed the drywell was very shallow. Also they had to cut this pipe to sort out the plumbing when the city put in sewers and the pipe going to our septic tank was under the drywell pipe. So they had to cut it and they reattached it later with a rubber sleeve and those metal pipe connector things you tighten with a screwdriver. Well my parents have been parking their RV right ontop of the drywell pipe. I was adamant that the pipe had been damaged for some time because of the water flow signs on the wall of the pit. Now I know that it was.

So X and Y are parallel to the screen and Z is perpendicular.

But its fun hearing it from the road's (and drain cover's) perspective of being sucked up towards the car.

[@crazyhistorian]

Matt explains how first you do the drainage, and then you put a layer of asphalt. In the meantime, in Croatia it is the opposite case. They put asphalt, and then the new company digs again to do electricity, asphalt goes again, then the new company digs again for pipelines, - II - (sign of repeating) sewage, - II - telecom...

[@Poldovico]

I went to an engineering university, and the convention we used was that X and Y are along the reference plane, and Z is through the plane towards the observer (because right hand rule). So if you're working with maps, Z will be elevation, but if you're working with cameras, Z will typically be depth and that will naturally map elevation to Y.

Even though I only work as a traffic control manager. The company I work for does sidewalks. From watching this I learned why they also do catch basins (as the hard surface of the sidewalk would change the amount of contributing drainage).

[@TheRegret]

i love these videos about niche infrastructure because people generally dont think about these things until they want to build a community and now they have to think about how the weather affects the area they've built on, or the structure's that were there to begin with. it's crazy how the previous videos follow the english version, which for a lot of viewers is probably overkill, but britain has a ton of old streets and infrastructure built so close together it's probably difficult to even get that kind of stuff in in the first place. not to mention math i never thought about like water rolling down a grass hill (i thought regular ground with grass absorbs water faster than what is simulated). i appreciate that this video is done with the limitations of the simulation but it also makes me realize that our american infrastructure more than badly needs an update, especially when matt said "we just add 40% to the rain data we've only collected for 50 years" there is a part of me that thinks american standards dont do the same.

[@HaralHeisto]

Y being vertical in computer games is an artefact of the way computer graphics evolved. Screen coordinates started as X for horizontal, Y for vertical. Then Z indexes got added for determining which objects are drawn on top. The arrival of 3d changed the z-index to a full dimension, and the matrix maths to project from 3d space to viewport coordinates is just that bit simpler to read when it doesn't need to include an extra rotation. By this point, it's just convention - it doesn't really affect the maths, and most developers never actually get involved in the 3d rendering code.

[@dkosmari]

Nah, it was just Notch being dumb. Plenty of computer graphics is done with Z up, precisely because you can trivially (without the need for a transform matrix, or skipping a field) take the XY or the XYZ to use for a quadtree or spatial hash, lined up with the ground plane.

Do have to mention that while the UK "officially" uses the metric system, we're technically one of the few that use both systems at the same time and often interchangeably for the same thing, for example milk, it's sold in pints and also litres depending on who makes it, and sometimes have both listed on the same bottle (again depending who makes it). As Matt mentioned, we still use mph and miles, you generally check the weight of items in shops in metric, though you weigh yourself in stone and ounces and your height in feet and inches. Quite sure the railway still uses the chain length in location identifier (miles and chains from London usually), though they do also have it in metric as well now.

Up-axis being either Y or Z is not the only variable in games, you also have Left-handed and Right-handed systems (this affects how Pitch-Yaw-Roll are applied). You are used to Z being up because you look at the map from the top. Some games use Y up because they start with side-view (like a Super Mario Bros) or because your screen has Y axis as the vertical one.

[@RamsesTheFourth]

Yeah as a 3d artist its sometimes really messed up to convert models from one program to another.

[@alexf3946]

30:21 In videogames, we use y as the height because of monitors... The idea comes from 2D games, where the x and y come from screen coordinates where x means the width, and y height. When devs where making 3D games, the extra "depth" was just added as z, making x,y coordinates easier to transform for sprites and that stuff. Today, we just kept it. Software designed for other purposes kept the x,y as the base plane, and z for height, which means that game devs need to consider what one software uses compared to others. For example: Blander uses z as the height, while unity uses y as height. If you manually export from blender to unity, you might need to tweak the import values to make sure it gets properly oriented.

There have been similar games made for other scientific uses, such as protein folding. I think the hard part, though, is that a game needs to be designed to be accessible and fun for people of all skill levels, which often means simplifying things to the point that the results aren't useful in the real world. You see this happen all the time with engineering games of factory automation, programming, or making circuits. While they all touch on interesting elements that make you feel like you're doing the real thing, the real job has 100x more complexity and constraints that mean it requires far more dedication to learn and to succeed.

Just imagine the nightmare of the residents when first the telco comes along, rips open the pedestrian walkway to put fiberglass in the ground, then 4 months later, the power provider comes along to repair some cables, then 6 months later the city comes along to repair the drainage pipes and gullies but since it's getting winter they don't finish the job.

little fact about roofdrainage in germany: our roof drainage systems usually go into some rainwater storage for own gardens or directly underground into the rainwaterdrainage from the road, without swamping over the greenery ^^

[@reverse_engineered]

As a strange counterexample, in my city in Canada, we are not allowed to capture the water and store it! I don't entirely know the logic behind it, but it comes down to not being allowed to divert the natural flow of water. I suppose it would make sense if taken to the extreme where you capture as much water on your property as possible and therefore withhold that water from your neighbour who would normally receive it.

[@0megaming]

@@reverse_engineered well, most times those barrels to collect the water can hold like 100-200liters of water and then simply just overspill. Regularly used at single family houses, when you have a garden, where you Tempo to use the stored water in the evenings of the dry season to provide it to your garden. (In the evenings, so that the burning mid day sun won't use the water drops as magnifying lenses and even burn the plants more)

My Grandad, who kept daily weather recordings, including rainfall (as a hobby) from around the 60s, until his death in the 2000s, told a developer that every 5-10 years, their fancy new big houses would flood. They do, every few years, millionaires whine.

Its so fun to hear you talk with so much passion about this. And its very nice to pick up some tidbits about drainage while you are at it :) keep it up ! You rock.

[@jochem_m]

I've said it before, and I'll say it again, watching someone enthusiastic and knowledgeable talking about their expertise is _always_ addictive.

Aw man, i wanted to see if that design would get rejected or not! great vid, i love nerdineering! (forgive the terrible word mash)

[@ashnodmtg]

I know I'm late to this, but I love these videos. Explained why I always have a huge puddle at the end of my drive, with the nearest drainage around the corner.

[@thebuilder9225]

Talking about the man holes being uplifted. A lot of our city’s man holes are welded because I don’t know about the UK, but in the US we have what we call drop neck trailers. We’re the front portion of trailer, would disconnect from the trailer itself. So you can load equipment without ramps and etc. Them trailers have engageable magnets that are safety features to help secure them 20Ton-100Ton loads on with the chain you would apply to help secure it to. Them magnetic were strong enough to brake a man hole in half if the magnets on the trailer, picked it up and hit the trailer right.

[@katejudson2252]

You should do a Baltimore bridge review after what happened last night! What can they do better?

[@Drahcar]

As an American engineer... I support the glorious metric system.

[@reverse_engineered]

As a Canadian engineer, in school we were taught to do everything in metric, but when I buy anything locally, it's all measured in imperial. Yet internationally, everything is metric, except that some companies will default to imperial to accommodate their typically American customers. It's all so confusing! But I stick to metric whenever I can.

[@Will-md3tt]

Much easier in chemistry too. I like that it's all base-10 measurements

[@i7moodws11]

hey matt! i am actually living in Qatar and i thin ki go by the road that you helped work on daily haha, big fan here and i genuinely enjoy watching your videos and i am planning to become a fellow engineer when i graduate from uni (engineering) too. thank you so much for the amazing content and i have seriously smiled countless times when i see a new video from you. ps: keep your editors dont give them anything they do the work just fine like this ahahah

[@Chuckdiesel86]

This is actually useful to me in a weird way! Recently I was walking around an area near where I live and I saw a sign saying "detention pond" and having never seen one called that before I naturally assumed our locals made a mistake making the sign. I'm happy to know my local people aren't morons!

[@Tall_dark_and_handsome]

41:16 peace, love, and I enjoyed the entire video! Thanks RCE!

You didn't actually check the design, which hurt my soul a little bit.

He wasn't being fined and that's all that matters, right? ;)

[@ShimmeringSpectrum]

It's fascinating to hear an engineer geeking out about their work and walking us laypeople through it.

[@Sonatengraf]

Love these videos in which you spread your engineering knowledge, as I've commented ages ago on your Infra series. I know it's probably quite the niche space, but maybe you could collab with engineers from other countries to talk about the differences in road drainage design. To an amateur, these videos are incredibly valuable. Is there like a European Association of Drainage Engineers? I mean, I'd probably already be happy about a ten-minute review à la “here are some documentaries RCE recommends if you want to learn more”.

[@onemanzu]

I really enjoy this, but can you do like … ‘over engineered drainage’ using something beside those tiny gullies and maybe more like the American style curb storm drains?

[@zamboughnuts]

I know, it's so hard to watch him just straight up ignore everything besides the UK-style ones...

[@Ddubbler]

i know its a bit off gaming, but perhaps you could try explain the physics behind the bridge collapse in baltimore this morning and replicate it in polybridge????

[@MarkGrayJr]

I love hearing experts nerd out and explain their areas of expertise. I'm TOTALLY invested in you finishing the rest of the scenarios! @realcivilengineer

[@Beateau]

I am sooooo excited to see another video of this! I didn't thin it would happen, but here it is. MORE! (Please.)

[@Dragongaga]

In my country it's actually illegal to just let water from your lawn or driveway drain onto the road. That's because in winter, when snow is melts during the day, the water can't properly drain or evaporate, instead it will freeze over night, which leads to accidents and injury. If you have a sealed, non-permeable driveway that falls towards the road, it's your responsibility to prevent the water from getting onto the sidewalk, mostly by having a narrow open pipe with grating on top all the way across your driveway, sometimes even two if it's too steep. For lawns, either the sidewalk is higher than your lawn, or your fence sits on top of a low concrete wall. Roof drop pipes will generally drain into another surface water drainage pipe or a dirt hole filled with lose rocks, so the water can actually seep into the ground quickly and not just sit on top of the dirt. You will NEVER see a roof gutter that just drains onto the grass. The goal here is to get the water back into the ground as quickly and efficiently as possible to keep the earth moist and permeable. If the earth dries up, it becomes dense and hard and is no longer able to take on any amount of rain water. Oftentimes there's actually a ring of lose rocks all the way around a building, directly at the borderline between the foundations and the lawn, so rain water coming down the facade can drain into the ground directly and won't stay on top of the dirt

[@mindiasferma7807]

i have commented this like 69 times already but did you know that 6+9=15 and 6x9=54 and by pure chance 54+15=69 so that means 6+9+6x9=69

[@ChrisPlaysGamesCPG]

i really enjoyed everything in this video. I know that you've transitioned over teh past few years to be more "entertainer" than "educator", but I always loved the education bits best, and I think that this application gave you a ton of room to demonstrate that. Strongest shapes are all well and good, but this is a great thing to have in the mix. Thanks for making the video.

[@Unzenexplorer]

I can't believe I watched all of that either but the passion shows through.

[@86liveZ]

at 3:11 in the eastern US (specifically PA) the company i used to work for would put in all the piping and do all the land removal and addition. So ,other than the storm pipes, most pipes were kept off the road onto the side under the yards, so its really interesting to see that different places around the world actually spread the lines across the road

[@vincentking2552]

I see the next level had calverts, and ive been watching a lot of (post 10) content who does calvert clearing usually from beavers causing dams and flooding. Its amazing to see how quickly some ponds and water levels drop after clearing.

Matt keep up with this sim it's super interesting and we can learn a lot from what you did IRL with it! And I think that it's like a relaxing time for the editor editing this! 37:55 yeah it happened recently too! In city circuit it was always a problematic because they are dangerous too if uncovered! Imagine your vehicle (in F1 made for the majority with carbon fiber) hitting a piece of metal (or whatever material) ar 250/300+ Km/h... yeah it's very bad! And nowadays it happens even more with the new generation of Ground Effect vehicles! (Had to search it up) "... An F1 ground effect car of nowadays can produce a 750Kg of pressure..." so that's probably how it's able to lift up a manhole 😄🤯 Oh aaand...
