See the attached picture for my river implementation. I simply used a
hightfield. Also find attached the source file for the heightfield. In  a
sense, your idea with the planes will work fine - my "water surface" is
merely the same heightfield displaced a bit upward and moved so a different
part of it is visible. And textured differently, of course!
