Both work - but in different circumstances. Ripple pattern works and are
easy to do - not so much with the pigment, but you might try rippling the
normals. However this only LOOKS like ripples. If you render close to the
water, it becomes obvious that the water is really flat. Height fields is
something I haven't tried - although I don't see why it wouldn't work - and
it would actually produce 3D ripples.
     All this only makes ripples however. If you want WAVES - that's a whole
new kettle of fish, and one I'm not sure how you'd crack. Waves are pretty
complex shapes really
