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

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.

@ahmedabdalfattah3450 4 года назад

That's impossible. To be a Ph.D. in waterway engineering, you need to watch like 11 videos or something.. at least.

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.

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

@acky91 3 года назад

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!!

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.

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.

@SuperTrunkspace 3 года назад

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 :)

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
