JBA Trust hydraulic flume showing how engineered structures affect flow in rivers (full video)
Ғылым және технология
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.

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.

Moral of the video: Upstream always slow Down stream always fast
@acky91

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'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.
Why is this so interesting??? KZread suggested it and once it started playing I couldn't stop watching it.
A 10 minute video has taught me more than all my teachers have!
"the kayak will not have a good time" and that is called a perfect drowning machine
KZread recomendations usually nail some of my science curiosity
JBA Trust, for everything related to water, I trust you.

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 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 :)
This entire channel is a hidden gold mine
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!
This is one of the best videos I have seen in my life.
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 came up in my recommendations. Right up my street. Most informative video I’ve watched for a long time.
Don't know how i got here but this is the best thing i have seen this week
Finally I can brag my water management knowledge infront of friends.
You guys have put SO much effort into this and it looks great and is very interesting. Thank you 😁
They didn't teach this in our Water Resource Engineering classes... Now I understand the concepts properly..
This is a summary of my 4 years of structural engineering. Good job
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..
Teached me more than everything I ever learnt in school

my favorite part was when they Introduced The Duck
humans: the earth raised all the water levels !! earth: you did most of that yourself first...
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!
MIght be the 2nd time youtube recommendation actually recommended something i watched through and enjoyed. Amazing video!
Мало что понял, но было интересно. И как это видео выскочило у меня в рекомендациях?
2:23 I remember this! Officially warning signs call it a drowning machine iirc
KZread must be reccomending these types of niche engineering videos to get us ready for something...
I stumbled upon this randomly and I enjoyed it way too much, informative, simple, interesting, just great!
Me : wow this stuff looks so fun! Also me : get "D" on fluid lesson
Me who don't even know how I came here and why I'm watching. My Mind: Watch it...
I did not search for this but this was completely entertaining.
I dont know why this was in my recommended but ngl I really enjoyed it.
This is literally just Bernoulli's principle put into action

I, for some reason, was recommended this. I'm not dissapointed, you guys seem proffesional
Video: water go splish splash 214,000 people: interesting
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
I'm so glad he explained what a bridge is, I was lost for a second there
Best random video I was recommended to watch in a while!
The Vortex control device blows my mind. So cool!
The sequel we have all been waiting for
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 the kind of vid that i want my son to watch rather than watching youtube content of other youtube vloggers out there.
Did not ask for this but did I watch every second of it with wonders in my eyes. WELL YES :)
love seeing engineering designs like this in action
I really apperciate this guys! I got which had missed!!
Amazing and clear presention that i have ever seen on how structures effect the river flow.
they are like better version of teachers, now i know how things work like that, so THANKS school.
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.
Excellent demo and all very interesting and with informative details! Thanks!
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!
THIS IS THE MOST INTERESTING THING I'VE EVER SEEN I NEED MORE WATER VIDEOS
I could watch this all day
I don't know why this video have been recomended to me, but was amazing. Hugs from Brazil
That's exactly what I am looking for. Thanks 👍
Good to know and to understand nature of the water to resolve the city flooding. Thank you.
This is really fascinating to watch it. Wish there was something like this was available when I was in school!!
I’ve learned a lot from this. Thank you
This video had my mouth hanging open since they put in the first object. This was very interesting and easily explained
I didn't search for it after watching i don't regret Great demonstration 🔥
THIS IS FREAKING INTERESTING , WATCHING IT WITHOUT EVEN SKIPPING 5 SECONDS AHEAD
Thank you youtube for the recommendation. learnt something new today. More respect for civil engineers.
This video was extremely enlightening!
I don't know why KZread reccomended me this , but, now I'll be able to judge each bridge I cross.
A comment from me that has already been said.. unsure of how on earth I landed in this KZread wormhole, however, fascinating! 👏👏
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.
This was so interesting to watch. I am glad I watched it.
This is a great and fascinating video, the presenters are very engaging. Thank you! Please do more
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.
incredible work!!! very easy of understood! very much thank you!
Yay! New JBA Trust video. Finally YT recommended this
