Improved 3-D beach evolution modle ocupled with the shoreline modle (3D-shore)

摘要

An improved 3-D beach evoution model coupled with the shoreline moel,named "3D-SHORE",was newly devleoped to estimate both the spatial bottom topography change and the shoreline change.In calculation of the shoreline change,the total longshroe sediment transport rate is estimated by integrating hte local sediment transprot rate in hte direction aprallel to the shorline from the breakign point to the run-up point.The applciabilities of the mole were verified through comparisons with bouth the results of the movable bed laboratory ezperiment and the actual beach evoluation.
