摘要 Udo, K. 和 Yamawaki, S.，2007 年。波浪和风作用下的短期背岸过程。 Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 237 – 241. 澳大利亚黄金海岸，ISSN 0749.0208 通过对 2004 年 9 月至 3 月日本开放海洋耗散海滩的日床高程、沙粒大小以及波浪、潮汐和风力条件的现场观测，研究了波浪和风对短期背岸过程的影响2005年。波浪和风影响指数分别由波浪上升水平和风沙输送率定义。结果表明，波浪对后岸沉积的影响大于风。此外，波浪和风都会导致后岸的沙子变粗。助跑波是对背岸过程影响最大的外力，其次是向陆强风和温和风。
ABSTRACT Udo, K. and Yamawaki, S., 2007. Short-term backshore processes under wave and wind actions. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 237 – 241. Gold Coast, Australia, ISSN 0749.0208 Wave and wind impacts on short-term backshore processes were investigated through field observations of daily bed elevation, sand grain size, and wave, tide, and wind conditions at an open-ocean dissipative beach in Japan from September 2004 to March 2005. Indices of wave and wind impacts were defined by wave run-up level and wind-driven sand transport rate, respectively. The results show that waves have larger effects than winds on backshore sedimentation. Furthermore, both waves and winds cause sand coarsening in the backshore. Run-up waves are the external force with the greatest impact on backshore processes, followed by landward strong winds, and mild winds.
