JBA Trust hydraulic flume showing how engineered structures affect flow in rivers (full video)
ฝัง
- เผยแพร่เมื่อ 5 พ.ค. 2024
- The mini flume shows the flow of water in a simple channel, driven by a system of recirculating pumps. It shows scale models of typical engineered structures such as weirs, bridges, culverts and debris screens. The mini flume is particularly useful in helping to understand some of the causes of flooding and how good design and maintenance of rivers and drainage channels can help to manage flood risk.

Two more of those vids and i'm gonne be Ph. D. in waterway engineering.
go to post 10, he got a lot vids with drains, culverts etc
Practical engineering youtube channel
true
I know it's a joke and all, but fully understanding these would at most put you at an undergrad level. Master and Ph. D are about use this knowledge to research and understand more.
That's impossible.
To be a Ph.D. in waterway engineering, you need to watch like 11 videos or something.. at least.
I don't know how I got here but this is the most interesting thing I've seen all month.
quarantine reccomendations
Same tho
Same here, I have nothing to do with this subject but I like it
same thing for me, on my side: most interesting thing I've seen all year. Engineers rule
same for me. i live in a country which have the highest number of rivers in the world, more than 2000+ rivers.
TH-cam: Here you go
Me: I'm not even interested in waterway engineering
TH-cam: Here. You. Go.
Gabe Larsen We’re not really sure why we got here, but now we all know about waterway engineering. TH-cam recommendations are great
Pretty much xD
Exactly 😆😆😆
Okey, i will check it.
Uhm, okey..I liked it.
YT recommendation, you did it again.
same but i was excited to watch it
"First, we need to measure velocity"
Tosses a yellow rubber duck into the water
I don't know how you could possibly get more scientific than rubber ducks.
Engineers tend to be a practical bunch, lol.
That is really how we measure velocities only difference being in real life the duck actually speaks
Haha that's actually how they measure velocity out there in the field too.... Sometimes simple methods are the most accurate..
urbanturbine I remember in my hydraulics class, we just threw a stick in the water and timed how long it took it to float downstream. Rubber duck is probably better. More visible.
I didn't know engineering involves so many rubber ducks 🦆
How do you think they make the ducks?
It’s just the one duck actually
I'm thinking career change...
And in real environment setting do they include clear pvc walls?
In fluid mechanics is practically a measure unit
Not gonna lie, this was fascinating and I'd like to watch an entire series.
Mee too, very interesting
The sequel is finally here
Edit: weird to see this at 2.4 million views. I remember it when it had 3 or 4 comments and views in the low thousands
I. Them we’re the days.
The TH-cam recommendation algorithm works in mysterious ways. I also got here by chance. Enjoyed myself with the video tho.
The Algorithm works in mysterious ways
I have no use for this information, but I find it very interesting.
As a Civil Engineer myself, I wish my professors taught me these with these examples. I would have continued as a Civil Engineer instead of moving to Information Technology.
as civil engineer my self shall i continue or run ?
@@oussamakada8355 both, i am continuing with backup plans
NEW WATER VIDEO!!
yay
yay indeed
I’ve honestly never been so happy to learn about something so random as this
Moral of the video:
Upstream always slow
Down stream always fast
It is not true, this level rising and slower velocity is from local energy losses. The slope. Of the river is higher in upstream and therefore velocity is higher. Downstream slope is slighter, velocity is reduced. Model is showing constant slope!!
I don´t have a river, why am I watching this?
You may fall into one
A wise man once said..."you are your own river".
D.M.
@@muhammadzaidhasan1426 I will now be careful around vertical screens
ok. i'm literally pricing up 2cm acrylic on the internet right now. i must build one of these. so much cooler than a fishtank.
Just put fish in it anyway.
Make sure to install a vortex control device.
Put the fish.. let them have an exercise this quarantine hahahahaha
Don't forget the rubber duck! 👍
What kind of pump there are use?
I've always wondered in geo classes that if a simple obstacle really rises the water level that much and effect so far away. This is perhaps the most intuitive resource to understand it. Fantastic video
I'm not an engineer in waterways nor a student in this field, didn't know most of these. Stayed because entertained and earned some knowledge.
Love how you guys illustrate how the water will actually behave...so clear and easy to understand. I never thought I would ever need to know this but recently I have been making a table top fountain project and the water flow speed was too slow and that's when I thought of this video and came back to look for you guys.
Finally, I have answers to the questions I never asked.
This entire channel is a hidden gold mine
Mechanical Engineers: "We will use first principles and solve any scenario"
Civil Engineers: "Let us just test each possible one"
Jonathan Rabe its the other way around. Mechanical Engineers more likely to have models and prototypes.
Civil Engineers only get one chance as every location is unique.
This is going to have a million views in a couple of weeks. I'm telling ya.
EDIT: Ha! Called it!
Yeah
No it wont have a million views ^^
@@nalyddoow9295 im leaving a reply here so I'll get notified
almost there
@@mathiasrasmussen7455 oops
post10 would never let that culvert getting clogged
Steffen Vetrhus post10gang
hahaha exactly!
Yep but he always gotta fix what others don’t, so as soon as I saw culvert I was like « yeah send more maintenance for those so that post 10 can focus on unclogging others stuff »
Post 10! ❤️
Why is this so interesting??? TH-cam suggested it and once it started playing I couldn't stop watching it.
This video is very important for kayakers, I think all kayakers should watch these videos before entering a river.
This reminds me a lot of my casting classes. We did a lot of fluid flow simulations to design molds for castings. A man named Dr. John Campbell took some xrays of castings while they were being poured, and found that water is actually a pretty good analog for molten iron. So some of the models people use to demonstrate casting techniques look a whole lot like what you're using there :)
A 10 minute video has taught me more than all my teachers have!
Perfect representation of the physics and underlying hydraulics in these structures. Thanks.
Loved "Open Channel Hydraulics" in college but that was almost 40 years ago. Nice work on the video. Thanks
so I've always wanted more of the coastal defence videi that I have watched like 10 times everytime It pops up on my youtube now I am saying we need more of these types of water mechanics videos
This is one of the best videos I have seen in my life.
I watched this video a few weeks ago, who knew that I’d need to find it again, along with your other videos to showcase fluid dynamics and Bernoulli’s principle!
The whole video is 100% worth watching ESPECIALLY for the end, I had no idea water could be control in such way! Loved it, thanks for sharing!
You guys have put SO much effort into this and it looks great and is very interesting. Thank you 😁
Another knowledge explained very briefly.. well done JBA Trust, you showed things that other people might not know that happens in their everyday life.. very good engineering info that would save many people in some developing countries..
This came up in my recommendations.
Right up my street. Most informative video I’ve watched for a long time.
My bother is an architecture student. 10/10 would recommend this to him.
TH-cam recomendations usually nail some of my science curiosity
"the kayak will not have a good time" and that is called a perfect drowning machine
MIght be the 2nd time youtube recommendation actually recommended something i watched through and enjoyed.
Amazing video!
I stumbled upon this randomly and I enjoyed it way too much, informative, simple, interesting, just great!
Finally I can brag my water management knowledge infront of friends.
Teached me more than everything I ever learnt in school
Obviously it didn’t teach you grammar.
I have been looking for information on how to represent these structures in a hydraulic model and this has proved to be very useful in helping me understand what I am doing. Please keep up the good work!
Amazing and clear presention that i have ever seen on how structures effect the river flow.
6:20 They even know how to freeze water for half a second! (Watch water closely)
What does this mean
It's a glitch
Мало что понял, но было интересно.
И как это видео выскочило у меня в рекомендациях?
I, for some reason, was recommended this. I'm not dissapointed, you guys seem proffesional
Very interesting and informative. The vortex control device is something new I've now learnt about today! Thanks!
"what are you doing step-screen?"
Dude! I was thinking the same thing! 😂
2:23 I remember this! Officially warning signs call it a drowning machine iirc
That’s got to be one of the best videos I’ve ever watched on here. Very interesting stuff.
These suggested videos are big brain energy.
my favorite part was when they Introduced The Duck
Me who don't even know how I came here and why I'm watching.
My Mind: Watch it...
JBA Trust, for everything related to water, I trust you.
This is a summary of my 4 years of structural engineering. Good job
humans: the earth raised all the water levels !!
earth: you did most of that yourself first...
Me : wow this stuff looks so fun!
Also me : get "D" on fluid lesson
Can I just add this is a fantastic video, I'm a white water kayaker and loved the explanations of all the different types of weirs etc. Wish they were building them more with recreational use in mind.
That was absolutely great ! Playing with water and teaching us about all that technical horsefeathers we dont need to know. And it was fun and I learned a lot!
This is literally just Bernoulli's principle put into action
Venturi effect
No hablo inglés, pero le entendí muy bien al vídeo uwu
i don't speak ur language but i can understand it uwu
The Vortex control device blows my mind. So cool!
Thank you so much for this demo. I much more understand the effects of these hydraulic structures. Anw Im a civil engineering student and this would help me a lot for my studies.
What you call a "stopper" is known as a drowning machine, tom scott has an excellent video about them
Also the duck getting stuck in diving is called a delta p event and a grate or screen is far safer then a hole as there is still flow with a hole you're body will block the hole and form a seal making you stuck there and probably die, delta p is horrifying
Video: water go splish splash
214,000 people: interesting
Thanks for the new patch update and water physics. Very appreciate it!
I don't know why this video have been recomended to me, but was amazing.
Hugs from Brazil
This is a great and fascinating video, the presenters are very engaging. Thank you!
Please do more
These videos show up in my recommended, I never search for them, but I have to say, this is very interesting and I love to learn about this kind of water physics.
Did not ask for this but did I watch every second of it with wonders in my eyes. WELL YES :)
Thank you youtube for the recommendation. learnt something new today. More respect for civil engineers.
They didn't teach this in our Water Resource Engineering classes... Now I understand the concepts properly..
Good to know and to understand nature of the water to resolve the city flooding. Thank you.
I didn't search for it after watching i don't regret
Great demonstration 🔥
Water works in very different and mysterious than what I thought.
Very interesting.
I'm so glad he explained what a bridge is, I was lost for a second there
This is really fascinating to watch it. Wish there was something like this was available when I was in school!!
Really a very good video to get educate ourselves and by showing this prototype model how water can be easily diverted really wonderful.
love seeing engineering designs like this in action
Wonderful! You are my favourite waterway engineering channel, alongside Practical Engineering. Please upload more.
This video had my mouth hanging open since they put in the first object. This was very interesting and easily explained
I don't know how this was suggested to me but it was really well made and explained. To top it off it was interesting to watch.
Nice demonstration of basic fluid dynamics. You guys surely made an A on that one. I'd give you one.
Excellent demo and all very interesting and with informative details! Thanks!
THIS IS THE MOST INTERESTING THING I'VE EVER SEEN I NEED MORE WATER VIDEOS
Best random video I was recommended to watch in a while!
Don't know how i got here but this is the best thing i have seen this week
TH-cam must be reccomending these types of niche engineering videos to get us ready for something...
This was so interesting to watch. I am glad I watched it.
Not sure how or why this was recommended to me, but I’m really glad it was. Very interesting video.
This is my first video of this channel but I'm going to stay here longer. I love scientific videos!
Very good! Love these videos. I'm a Engineer from Brazil. 🇧🇷
That's exactly what I am looking for.
Thanks 👍
I remembered seeing this video a couple years ago and could not remember to name of it, I searched for about 20 minutes after remembering that I need to know that title and I was not disappointed
i never searched for this,
i guess i liked it once or twice
but every odd year
i get a video on waterway engineering
Nice.
Don't know how I got here but I watched the whole video and enjoyed every second of it.
I could watch this all day
This video was extremely enlightening!
For civil engineers, this is a great way to demonstrate how Water Resources Engineering works! It is hard to believe, otherwise, by just working through formulae.
