I've had Win 10 for like, 2 years now and I still have no way of capturing video from AC. So here's a gif made of 3 random screenshots...

I'm not gonna say it's self-explanatory cause I had to google it...
txNormal should contain macro scale waves which move relatively fast in the direction waves visibly go (towards shallower water or towards currents). This part's more set up via UV mapping than parameter.
txDetailNM should contain micro scale waves which move slower in an oblique direction.
detailMult should be an irrational number, to avoid the 2 textures tiling neatly, likewise the 2 speeds should not have a handy GCD. (so for example: mult of 2.0 is an integer and bad, 2.09234 is 104617/50000 when expressed as a fraction which is much better. If in doubt use phi, or 1.618033988)
I believe 1.0 in the speed variables is +1 to uv per second, so you probably want more like 0.05 sorta thing to start with. Depends how big the texture is.
General material settings would be a dark brown-green diffuse (the river in the gif is muddy so it's more brown), with fresnelC 0.04, fresnelEXP 4, fresnelMAX 0.66 or so.
For redistribution only the _ps and _vs files in system\shaders\win\ are strictly necessary, the rest's so kseditor can operate.
