Abstract
The aim of this study was to investigate a runup height of drifting litter due to waves on the cross shore between shoreline and sea embankment in the Fuji coast. Field investigations were performed by photographically recording debris in 3m×2m quadrilateral areas using a digital camera along transects extending from the shoreline to the sea embankment on a section of sandy beach. The number of drifting litter on the quadrilateral area was counted from the personal computer display inputted digital photograph, and arranged graphically by relating to the cross shore section. As the result it was found that, (1) the cross shore distribution of litter is not uniform and has a few peaks, (2) that the litter runup height at the first peak in the nearest shoreline is indicated with the surfsimilarity parameter using the maximum wave characteristics selected from the order of wave height before the field survey through the one year observed wave-record.
