Abstract

  In this study, to examine the topography change of natural beach in semi-closed water area, field observation on the sediment transport in the vicinity of shoreline by boat waves, image analysis of aerial photographs to grasp medium, long-term topographic change and numerical simulation on tidal current and wave were carried out. Study site is Omaehama Beach which is located in the closed-off section of Osaka bay, Nishinomiya City, Hyogo prefecture, JAPAN. In front of the water area of Omaehama Beach, most boats round trip along the coast line, the deviation of sediment transport to one side or the other wasn't observed and we couldn't find the distinguished shoreline change. On the other hand, in terms of medium, long-term topographic change, Omaehama beach remains unchanged due to near landfills which prevent offshore waves.
