Summary
A numerical analysis of sediment transport in Amitori Bay, Iriomote Island, Japan, reveals distinct seasonal patterns and the impact of extreme weather events on sediment distribution. During summer, sediment particles from the eastern reef are more prevalent than those from the western reef, while winter shows an almost equal distribution between both reefs. Extreme events like Typhoon 1109 and heavy rainfall lead to widespread sediment dispersion across the bay due to strong winds and increased river flow. The study used a multi-sigma coordinate coastal ocean model (CCM) to simulate water movement under varying conditions, followed by particle tracking analysis to assess sediment transport dynamics.
