Field trip to Daytona Beach, Ponce de Leon Inlet and New Symrna Beach in Florida was made in September 1996. Past beach changes and present results of field observation were compared around Ponce de Leon Inlet, where sand bypassing was once carried out. It was revealed thaton the downcoast of this inlet beach erosion is now underway to cause beach scarp along the sandy shoreline. Eroded coast is protected by seawall, but foreshore width is too narrow for recreational usage, implying the necessity of future sand nourishment. Beach access at many coasts in Florida is compared with the situation in Japan and future improvement method in Japan is proposed.
