Yearly, the concern on environmental problems of the earth is growing on. One of the typical issues is desertification. To inhibit harmful effects of desertification, confirmed prediction methods which clarify mechanism of desertification are required. It is expected that numerical simulations are useful for the purpose. However, the numerical procedure and the physical model for predicting have not been established yet. Hence, our purposes are to construct the holistic simulation technique which reasonably reproduces sand transfer, and to apply it to create an effective prevention method of desertification. In this study, three dimensional simulations are carried out in order to compare our results to experimental data. Though results are qualitatively similar to experimental data, quantitatively-correct results are not obtained.
