Research Abstract |
Sand dunes are found in many places such as deserts and the surface of Mars. The morphology depends on the wind directions and the amount of sand. Then we investigated morphology of sand dunes under the various environmental conditions in numerical simulation. We reproduced barchan, linear dune, seif dune, star dune, drop dune and network dune. In addition, we studied time evolution of the shape deformation qualitatively.
