🏜️ Sand Dune Migration (2D)

A 2D cross-section simulation of a barchan sand dune migrating under wind: real saltation-driven erosion, downwind deposition, and slope relaxation at the true 34° angle of repose.

⚙ Under the hood

A 2D side-view simulation of a barchan sand dune migrating under wind. Real aeolian sand-transport physics erode the gentle windward slope by saltation and deposit sand on the steep lee face, which is capped at the true 34-degree angle of repose. Adjust wind speed, direction, vegetation cover and time speed to watch the dune reshape and migrate across the desert.
