Somewhere I have a paper describing something like that.
I recall an antenna at ground level or actually a little
buried, and its effective height was related to the depth
of the water table below the dry sand.  Maybe a well or
borehole was used to connect to the 'ground' plane.

I'll see if I can find it.
