sand ripples
Dune surface waves
Sand ripples are the small, regularly spaced ridges that form on sandy surfaces when wind or water flows across them.
The pattern emerges from the interaction between moving fluid and loose grains—each ripple creates turbulence that shapes the next.
You see them on beaches, dunes, and riverbeds: The sand ripples caught the morning light.
