    Abstract

    Wave and wind impacts on medium-term backshore processes were investigated in terms of backshore topography, sand grain size, and wave, tide, and wind conditions at an open-ocean dissipative beach in Japan from 2003 to 2005. Indices of wave and wind impacts were defined by wave run-up level and wind-driven sand transport rate, respectively. Changes in spatial topography and sand grain size show that bed accumulation and sand coarsening due to both wave and wind actions at seaward slopes of sandbank and dune. Linkage of the wave and wind impacts is necessary to better understand the beach processes.
