so why didn't they cover this or better yet drill a tunnel under the city for the water to run. look at all the space saved can be used for actually something good capping could put hole h.way overtop of that river. . silly not too

​@@zenlei8258in an ideal world this would be true, but in heavily populated areas where "minimal planning" occurred & prevailed for over 100 years... lakes don't adequately protect the water reserves. More specifically, man-made lakes do not protect the costs that have been expended to capture and direct storm waters. Like this video explains "money and space" are the most important concerns for successful water retention in densely populated areas.

@@PureMagma Some China lakes is doing this job. The man made lakes have very less water by pumping water out during dry season. During heavy rain fall the lakes will store this excess water temporarily. So less water flow into to residents area and flood can be avoided. It work all the time with proper planning.

Oh they're very much a possibility. The sewer one especially as I have a lot the research down but it seems like a big video.

10:40 In the Early 1980's there was a huge flood in my home town. A few years later I became friends with another kid who had been crossing a flooded street. He turned his head for a second and when he looked back his friend was gone. The water was a bit less than knee deep but it was muddy so the road was not visible under the water. He thought his friend had just tripped and expected him to pop up in a second, when that didn't help he started to get worried and started walking around where his friend had been when he nearly fell into an open manhole. He called for help but this storm drain flowed directly into the bay and there was very little hope. They never did find a body. He said it was weird how you can be talking to someone one minute and the next they are just gone. There was no splash no cry of alarm, his friend was just gone. After this the city started welding the man hole covers on. Not so strongly they could not be opened, but enough that the water could not blow them open in a flood.

Easily the best video on stormwater infrastructure I’ve ever seen. You really made a boring topic EXTREMELY interesting. Shoutout to all civil engineers that do amazing work that nobody takes the time to appreciate.

Wow, thank you so much. I tried my best to help transform the way they see the world around them. Hopefully they can now see what's been done

Underrated af. This video shows the shift in the philosophy of stormwater management, from making the problem go away as fast as possible (conveyance), to holding them in place for as long as possible and not let it be a bigger problem down the line (retention). Interesting thing about Tokyo and storm management is that it goes back to the Tokugawa Shogunate period. Edo is very flat and prone to flooding and as such the shoguns started flood mitigation efforts even during the Closed Doors period. They rerouted the most of the flow of the upstream rivers into Tone River, and in part making it the longest river in Japan. Then in the Imperial era giant bypass channels with giant floodplains were constructed, which uprooted quite a bit of homes. Not to mention dams.

Wow, thanks for the kind words and the added comment about the history. I didn't know that and I might cover tokyo and flooding in the future.

I knew you were going to talk about Philadelphia at some point. The city and its largest neighboring county, Delco, are both BELOW sea level and adjacent to the Delaware River. We've had heavy flooding in the past but it has improved significantly over the years. During hurricane Sandy the only thing preventing my house from being swept away was the genius engineering of the river right behind my property. I remember right after the storm sitting at the edge watching the water speed past what must have been over 30 miles an hour. In Ridley Park there is a gigantic recreational field called the "Hollow" that sits in a massive valley, with a small river at its bottom. Back in the 90s, according to my parents, the entire park used to be a lake. Now it's part of the genius engineering that keeps the area dry.

Philly had the vine street expressway fill up in 2021 I think it was. While that was due to lack of working pumps I do wonder if it partially saved the neighborhood from filled up basements. Philly also has that river nobody can spell without using Google, which is funny because its pronounced like Google. Fortunately all my area in SNJ got during Ida was an EF-3 tornado.

Truly amazing the amount of time you dedicated to this is incredible. I also loved your detailed animations and even quick but still visible mathematical explanations. You also gave me some really cool japan visit ideas once I eventually can do that. I might suggest in the future though that maybe you try to collaborate with other creators to save you time on your hard work. I could see that you looked at practical engineering's video but maybe it might be a good idea for you to reach out for experts to explain topics to you instead of trying to understand it by reading (and losing those 8 hours for the math part/animation and everything). That hard work definitely paid off in the quality of this video just an idea to try to save you time but it's not necessary if you can't or prefer not to make your videos that way.

Shout out to the Manning Formula! As a young civil engineer 35 years ago, I was given a circular slide rule that was based on the Manning equation and it was so intuitive to properly size storm pipes - and is just as handy today even with the proliferation of computer software.

Mannings formula is not sufficient in most cases. To do things right you also need to consider inlet and outlet control. I have found that most general civil engineers forget this in practice.

Fantastic video. Well presented, interesting topic.

I’m from Houston and we have all sorts of basins for managing rainwater all over the place. As soon as I saw that soccer field, I knew that it was only a field when it wasn’t rainy :P I had no idea about the stormwater management in other places! It makes so much sense that people elsewhere would use the same techniques-after all, if it works it works-but I’d never considered it before. The water infrastructure down here is so prevalent, but I’ve struggled to find maps and data about how each piece specifically works, especially the inaccessible, invisible underground parts. And of course, finding the data still leaves interpreting and understanding the data ^^;; I’m glad you’ve put together this video!
