That looks pretty cool, the devil is in the details but fundamentally it's just a few systems plugged together..
Ie. It's a spline mesh with a nice Shader that uses distance field based flow maps to place the foam.
Spline mesh generation can be a little tricky but it's probably worth having a go at it and then posting up here for help when it goes wrong. I've done a fair bit with it as I'm sure many others have.
The Shader is basically just a scrolling water material that warps UVs and masks in foam where a flow map tells it to. I've seen several tutorials on that.
The distance field flow maps are relatively straightforward to get working but a little tricky to visualise. Again, find a tutorial and post back if it doesn't work.
