Does anyone know what youtube video this webm came from?
Or at least know what sort of physics is occurring to the water here? Googling fluid dynamics videos didn't help

Waves in an open channel?
I can't open webms so guessing it might be interference
>>7940265
It looks like a regular wave, that just happens to be contained in a narrow trough.

1D transverse waves
The video is from the new Dutch wave simulator. Just google that. Its the largest Tsunami wave simulation created by mankind. (ooooooh !!!! )

I think it is the Delta Flume, I remember reading about it a while ago.

Pretty cool if you ask me.
From what I saw in the video, the wave breaks because its top falls away from its base. But what makes the wave go faster at its top than at its base in the first place? I never saw this at my optics class. Or mechanics, differential equations, etc.

https://en.wikipedia.org/wiki/Breaking_wave
>The most generally familiar sort of breaking wave is the breaking of water surface waves on a coastline. Because of the horizontal component of the fluid velocity associated with the wave motion, wave crests steepen as the amplitude increases; wave breaking generally occurs where the amplitude reaches the point that the crest of the wave actually overturns—though the types of breaking water surface waves are discussed in more detail below
>>7940265
step1: nonlinear interactions create wave-wave coupling
step2: because energy is transferred across wavelength-space, at some point wave steepening occurs
step3: ???
step4: profit, I mean wave-breaking

sorry I forgot to add buzzwords:
* it's a shallow-water system, which is a specialized version of the equations of stratified fluid dynamics
* one famous example of equations describing very steep shallow-water wave-crests is the Korteveeg-de-Vries equation, which can be derived from the shallow-water system.
* KdV solutions are, amongst others, Solitons. Those are pretty nice waves where the steepening due to nonlinearity is balanced with dispersion of single-wave modes.
I hope those buzzwords satisfy your lust for advanced fluid-dynamics.

Op here
You're a legend. Cheers

yep, pretty much.
also, look at how the taller soliton overcomes the smaller one, in agreement with the fact that the soliton's speed is proportional to its amplitude. I wonder what is the physical reason for wave breakig here and why doesn't dispersion create a train of regressing solitons before you reach gradient catastrophe.

Hey! That was MY laugh. GIVE IT BACK!
