A barchan dune has a crescent shape with horns pointing downwind and forms in areas with limited sand, while a parabolic dune has a U-shape with the horns pointing upwind and forms in areas with abundant sand. Additionally, barchan dunes are individual and migrate due to wind direction, while parabolic dunes are stationary and often found in coastal regions.
