  • RECOVERY OF LITTORAL SYSTEM ON SENDAI COAST AFTER THE GREAT EAST JAPAN EARTHQUAKE TSUNAMI  [in Japanese]

    HOANG Vo Cong , TANAKA Hitoshi , MITOBE Yuta

    … The recovery of littoral system on Sendai Coast, Miyagi Prefecture is further investigated in this study. … By adding two more years of shoreline position data extracted from aerial photographs and utilizing the Empirical Orthogonal Function (EOF) analysis, the recovery of littoral system of the coast can be revealed. … As a result, the sediment budget has been also changed. …

  • FIELD SURVEY ON THE MECHANISM OF FLOW AND SEDIMENT TRANSPORT IN THE ISHIKARI OFFSHORE COAST  [in Japanese]

    HONMA Daisuke , KUBOUCHI Atsushi , SAKIKAWA Mitsuhiro , SUZUMURA Akihiro , YAMASHITA Toshihiko

    … Toward comprehensive sediment manegement that promotes coastal conservation, the mechanism of wide-area littoral drift needs to be understood.Research on sea sand drift has thus far targeted relatively shallow sea areas, such as the surf zone. … For wide-area sediment management, however, a study should be extended to include the role of grain in sand drift and to include sand drift in deep-sea area. …
