2003年至2005年，从日本一个公海耗散海滩的后岸地形、沙粒尺寸以及波浪、潮汐和风条件等方面，研究了波浪和风对中期后岸过程的影响。波浪和风影响的指数分别由波浪上升水平和风驱动沙输送率定义。空间地形和沙粒尺寸的变化表明，沙洲和沙丘的临海斜坡在波浪和风的共同作用下，床层堆积和沙子粗化。为了更好地了解海滩过程，有必要将波浪和风的影响联系起来。
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.
