IMPROVED 3-D BEACH EVOLUTION MODEL COUPLED WITH THE SHORELINE MODEL (3D-SHORE)

Abstract


An improved 3-D beach evolution model coupled with the shoreline model, named "3D-SHORE", was newly developed to estimate both the spatial bottom topography change and the shoreline change. In calculation of the shoreline change, the total longshore sediment transport rate is estimated by integrating the local sediment transport rate in the direction parallel to the shoreline from the breaking point to the run-up point. The applicabilities of the model were verified through comparisons with both the results of the movable bed laboratory experiment and the actual beach evolution.
