ANNUAL MODEL OF SWASH ZONE BEACH PROFILE CHANGE FOCUSING ON BERM FORMATION AND EROSION

摘要

A swash zone beach profile change model focusing on berm formation and erosion proposed by Suzuki et al. (2013) was reexamined in order to apply the model to longer computation periods. The model was applied to the calculation of three months of beach profile change, and the results were compared with field data and the computational results of previous models. The model was also applied to the calculation of one year of beach profile change and compared with field data. The model was found to well predict not only the shoreline change but also the beach profile change, including berm formation and erosion, for both short term and seasonal changes.
