EFFECT OF AEOLIAN SAND TO TOPOGRAPHIC CHANGES ALONG EAST ENSHU-NADA COAST

Abstract

 Long-term change in windblown sand was estimated on the basis of the changes in shoreline and width of sand dune using aerial photographs. Based on the total volume of windblown sand necessary for the development of sand dunes in the geological time scale at the Enshunada coast, the rate of windblown sand toward inland was calibrated as well as the determination of longshore distribution of landward windblown sand. Along this coast, longshore component of windblown sand was estimated to be 1.9×10⁴ m³/yr at maximum, which accounts for 25% of all the longshore sand transport.
