    Engineers need to be able to predict how water will behave in order to design structures that manage or control it. And fluids don’t always behave the way you’d expect. On this episode of Practical Engineering, we’re talking about one of the most interesting phenomena in open-channel flow: the hydraulic jump.

Thanks for sharing this wisdom, never considered this wisdom... but it's for sure worth knowing as I moved to nature from the City and I'm looking forward to backpacking through Bankhead National Forest right near me in Alabama. Again, I came back here because I saw your comment and responded to in on Samm Shepherd that I just found on YT only to seek out the latest video was his Father. God Bless Practical Engineering and thanks again for sharing your learnt with us. Keep blessing us, but most important, your family and God. Amen.

Thank you, ever since hearing this mentioned in a documentary about aqueducts build by laying out terracotta pipes through mountains with open channel flow in them I wanted to know specifics. The pipes needed ambient pressure and steady flow in them to remain sealed, thus they needed very constant gradient avoiding the water to jump anywhere.

The best place to learn what requirements you need to enter an engineering discipline is from a college or university school of engineering. They will have the course work required on their website. Another place to go is your guidance counselor.

The acrylic demo just looks like water crashing into a significantly deeper reservoir. That's not very impressive. Of course a 3mm thick sheet of fast moving water is going to stop when it hits a pool that is 10x deeper. The sink demo was much more impressive to me.

Hydraulic Jump also occurs in another fluid... When air moves over a mountain range, a hydraulic jump can form on the other side and condensation can result, although it is often confused with the much more obvious Lenticular cloud of "wave lift", a separate phenomenon.

That hydraulic jump at 3:58 propagates just like a normal shock. This is so cool--I've never seen the analogy with supersonic flow so clearly! Just replace the sound speed with the surface wave velocity. So this really is rocket science!

Great content, as always, but dude... Your post-video spot was really quite... Creepy and disturbing. The uncanny valley of trying to mix the personal with a mechanical dictation of a script seemingly provided by the sponsor made me actually reconsider the continuation of my current plan with the provider. I had no idea if your wife used to work in China, but after this spot I'd see that as less of a probability than before. The whole spot is so blatantly dictated by the marketing team of your sponsor (whether it is "somewhat stretching the facts" or a downright lie) that it portrays you as disingenuous and your sponsor as downright shady. A consumer reads into these as they would to an unsolicited email advertisement on male enlargement products. Please, for the love of god (as much of an atheist I might be), never accept further sponsored scripts superficially tailored to you. Either recite a generic script, which the consumer can recognize as such, or write your own script that's true to you (the LTT-approach, not readily available for smaller channels). And the same goes for advertisers, don't repeat this faux pas. There's no natural middle ground. Write the script or let the content creator write it.

They're also infamous for killing people. Especially hydraulic jumps at the base of low head dams. The hydraulic jump there almost always causes the water at the surface to flow backwards, so that things that float (such as tourists in canoes) get trapped there and drown. "It's only a two foot drop, and a slight incline. I'm sure we can paddle past it without beaching the canoes. How bad could it be?"

Wary interesting video that I fund by luck. First, I have no knowledge on the subject at all!! But I am thinking if you build a model of a dam or something to investigate on how water will behave, do that give any usable data at all? What I mean is that the water drops will be totally different in size, compared to the model and the real structure.

I'm sorry but I just don't get this video or its intention. A very simple and obvious physical phenomenon is explained so long and with such vague examples that it leaves the viewer more confused and uneducated that he was before he watched this video. When a fast moving stream of water hits a still body of water it slows down and swirls in all directions. What the heck else is to it?! What were you trying to explain?

OP should take a whitewater kayaking class. The opportunity to explore natural water flows through whitewater paddling is huge. It's a ton of fun and a great experience for us engineering types. Paddlers tend to call hydraulic jumps "holes" or "hydraulics". There are dangerous ones and fun ones, depending on the size and the "corners". If the corners of the hydraulic are downstream, then it makes it easier to get out. Big hydraulics with upstream or even corners can be deadly.
