I think I once did something similar, but on a smaller scale, using a combination of random and noise shaders. IIRC, the random shader was static/constant and used to produce the basic form, with the noise shader being animated, via changing the seed, I think, to slightly modify the random shader's basic form over time. The material was then applied as a parallel map which was shifted over time in the direction I wanted the 'waves' to move. A final tweak I now add to most ground bump maps that recede to a distant horizon is to link the bump amplitude to the camera distance so that the bumps reduce in height with distance from the camera - this can drastically reduce the aliasing artifacts I was otherwise getting in the far distance/on the horizon.
