Short-term and long-term topographic changes of Nakatajima Dune associated with beach erosion and coastal forest development were investigated based on aerial photographs and the data of wind and regular field survey. Dynamic properties of the dune development and topographic change were obtained by the field survey showing that the edge of the dune develops 6m-8m per year although the topography of the dune keeps equilibrium. Sand transport rate was discussed by comparing topographic change with estimates by the practical formulae of wind blown sand. The formulae tend to predict smaller amount of sand transport in winter and larger amount in summer, which may be due to rainfall and vegetation.
