QUOTE (Marz @ May 26 2006, 04:38 PM) Thanks for the post. Dumb question of the day; what is the difference between a megaripple and a small dune? I always thought aeolian ripples were just "micro-dunes", but this paper makes it sound like they are different beasts. Aren't they both formed by saltation? Does a dune require different grain sizes to allow it to form classic dune structures, whereas a ripple implies only small waveforms are possible?
