利用航拍照片对纳纳基塔河口周围的岸线进行了分析，揭示了河口左右两侧的不同行为。河口左侧的岸线比右侧的岸线有更大的动力。将经验正交函数(EOF)方法应用于海岸线数据，揭示了海岸线的变化规律。第一种变化模式反映了跨岸运动，表现为沿海滩的均匀进退运动。纳纳基塔河口附近的岸线变化以跨岸运动为主，表现为约80%的第一模贡献。第二种变化模式描述的是沿岸泥沙运动，表现为河口左右两侧不同的岸线运动。沿岸运动对纳纳基塔河口周围的岸线变化的贡献率仅为10%左右。第二种模式还揭示了河口对沿岸泥沙输移的影响，其特征是左右两侧岸线响应不同。
The shoreline analysis around the Nanakita River mouth has been performed by utilizing aerial photographs to reveal the different behavior between left and right side of the river mouth. The shoreline on left side of river mouth has been moving more dynamically than the right side. The empirical orthogonal function (EOF) method is also applied on the shoreline data to reveal the behavior of shoreline change. The first mode of variability reflects the cross-shore movement which is shown by uniform advance and retreat movement along the beach. The shoreline change around the Nanakita River mouth is dominated by the cross-shore movement which is shown by around 80% contribution of first mode. The second mode of variability depicts the longshore sediment movement which is shown by different shoreline movement between left and right side of river mouth. The longshore movement only contributes around 10% to the shoreline change around the Nanakita River mouth. The second mode also reveals the influence of river mouth to the longshore sediment transport characterized by different shoreline response between left and right side.
