how to mix procedural textures for a natural waves of sand displacement effect? I want to achieve a nice wave procedural texture in order to get a realistic sand displacement effect. here is my current set up 



but I want to waves mix more randomly in order to give brunchy like look as shown below 



I made two slightly different located wave texture and tried to mix them with a suitable mixRGB node, however I couldn't manage to find a correct solution, all I cannot get a good result but only like below 



EDIT: I have played around a little bit more with the mixing option, I still couldn't figure out branching though



(thanks to for the video which made me started work on it )
You can distort a texture using another texture, like this:

Or you could mix bumps and displacement with other textures:



If what you are after fake relief (or bumps maps), but not real geometry displacement, this would work fine. Otherwise I would recommend using a displace modifier.
