Abstract

Short-term topographic changes of the Nakatajima dune, which is located on an eroded beach on the Enshu-Nada coast, have been investigated with continuous field surveys over two years period (2007-2009). Measurements of wind and wind-blown sand transport rate were also carried out several times in winter. Based on the field data, overall properties of the sediment transport on the dune are first described in the paper. Eastward migration of the dune is then indicated with relation to the topographic changes and the distribution of the sediment transport rate. Quantitative estimate of the average volume of transported sand are well predicted by some existing formulae
