@GenoWrites: Korash is right, although I just use the magic wand tool in PS to select the area around the terrain, and then use Select > contract (Select > expand, if I select the terrain instead of the water). Then I use Edit > Stroke; for the ocean water ripples, I think I used 3-5 px strokes, but for smaller bodies of water I drop down to 1-2 px. Then I blurred it a little, dropped the opacity, and set it to multiply.
