Sliding, rolling, leaping and making sand waves

  • J. R. L. Allen


Have you ever stood by a flooded mountain stream? Pebbles and cobbles are probably being audibly carried over the bed. From the evidence of their frequent collisions amongst themselves and with debris stationary on the bed, these stones must lie in dense array close to the stream bottom, to form what is called the bedload. However, this load is most unlikely to be visible, on account of the turbidity of the water. The smaller and more uniformly dispersed particles which make the current turbid are evidently being transported in a different way than the stones keeping close to the bed. They constitute the suspended load of the stream (Ch. 7).
