Abstract
The shoreline position in alongshore direction around the Nanakita River mouth was measured from aerial photograph which have been taken every 2 months in 20 years. Empirical Orthogonal Function analysis was used to decompose the data into the dominant mode of shoreline variability for left and right side of river mouth. The results were also examined in relation with wave parameter and river discharge. The first mode shows the same shoreline movement between left and right side which reveals cross-shore process. The analysis of second mode and its correlation with river discharge reflects the influence of long-shore process. This mode also reveals the influence of river mouth in interrupting the long-shore sediment transport. The higher modes reflect the formation of beach cusps in relation with wave parameter.
