Abstract Dune dynamics includes morphology, composition and formation process. There are mainly three methods used on formation process study: field experiment, physical simulation and numerical simulation. At the moment, with the technical development of 3S and computer, the dynamic numerical simulation on formation process of sand dune is very active. The flow variation around sand dunes results in difference of shear stress, which makes control effect on the pattern of sand dunes. The mainly used methods and achievements on the flow around sand dunes are presented in this paper.
