In this video, I discuss flume experiments and how bedforms also vary with grain size. Diagrams are from John Southard's excellent LibreTexts book "Introduction to Fluid Motions and Sediment Transport" geo.libretexts.org/Bookshelves/Sedimentology/Book%3A_Introduction_to_Fluid_Motions_and_Sediment_Transport_(Southard)
