A short-term swash zone beach profile change model proposed by Suzuki and Kuriyama (2009) focusing on berm formation and erosion was improved using the distribution curves of cross-shore sediment transport rates for berm formation and erosion determined by the slope of the curves at the inflection points. The improved model was applied to the calculation of three months beach profile change, which results were compared with field data and the computational results of Suzuki and Kuriyama (2009). The present model was found to well predict not only the shoreline change but also the beach profile change, including the berm formation and erosion, compared to the model by Suzuki and Kuriyama (2009).
