    I live not far from Kenetcook River and have driven over and along it often, Don't recall that bridge site off hand but am looking forward to spending an afternoon tracking it down.

    Thanks, great and helpful video. Just a thought---the word "celerity" is related to the word celery---celery (swift) is so named because it grows so fast. Neither here, nor there. Thanks for the explanation---better than my text book.

    WHat do you mean by flow depth?

    You state "Dune size scales with flow depth; ripples scale with grain size instead". There are what are known as mega-flood ripples (such as the Camas Prairie ripples). These are over 30 feet high. Were they scaled up as a result of grain particle size? Or flow depth? Surely they scaled up in size due to flow depth.

    Hi Matthew, what sources did you use in this video? specifically what sources did you use to distinguish the difference between a ripple and dune?

    Hey Mr Clapham, thanks for the helpful video. I have a question though (that I believe you haven't answered in the video):
    Unidirectional ripples normally form because of an obstructing object that makes sand to collect and finally move. But how comes, especially in deserts, that ripples are not local but show up in infinite fronts? I mean, hard to believe that those endless crests were formed by a single object.

      Indeed they were not, neither in windblown nor water created ripples or dunes.
