In this video, I describe variations in geometry in dune and ripple cross stratification/lamination due to non-linear bedform crests.
David Rubin at the United States Geological Survey has posted numerous excellent animations of how bedform geometry influences cross stratification. They can be found at: walrus.wr.usgs.gov/seds/bedforms I particularly like these two animations for showing the effects of linear vs sinuous ripples: walrus.wr.usgs.gov/seds/bedforms/movie_pages/movie5.html and walrus.wr.usgs.gov/seds/bedforms/movie_pages/movie34a.html
