Ripples patterns in wet sand at the beach

Ripple patterns in wet sand on the seashoreThe shape of natural abstract sand sculptures, like these ripples on the seashore, result from complex interactions of water and substrate which are the subject of much research in the field of fluid mechanics. They are described as “small-scale three-dimensional bedforms due to interactions of an erodible bed with a sea wave that obliquely approaches the coast, being partially reflected at the beach” (Roos & Blondeaux 2001). Different combinations of three main perturbation agencies create different ripple designs.

  1. Beautiful small-scale three-dimensional bedforms due to interactions of an erodible bed with a sea wave that obliquely approaches the coast, being partially reflected at the beach Jessica!

  2. I love the designs of sand ripples. When photographed to fill the frame, as you have, you can really play with the light and black and white to make very interesting images.
