The spatial and temporal changes in aeolian sand transport are important in modelling wind erosion and parameterizing sand dunes and ripples. In this study, we explored the wind erosion processes that occur in sand beds using a Trimble 3D laser scanner. We found that the erosion intensity varied wit...
