Notes:
In this study, to conduct numerical simulation of desert physiognomy forming process infixed, semi-fixed and free sand desert field by considering the sand flow process by wind, thenumerical model based on the hydrodynamics and sand grains kinemics are proposed. For analyze theactual characteristic of sand movement phenomenon, the stream flow field and desert flow field areintroduced and mathematical model for numerical analysis are established by considering the sandshape, size and mass in order to describe the fixed, semi-fixed and fully free sand desertphysiographical process. Then according to the real fixed, semi-fixed and free sand flow field bycoupling with stream flow field, several models are made and numerical simulations are conducted
