Transport properties of soil particles in Sakiyamawan–Amitoriwan nature conservation area, Iriomote Island, Japan

Seasonal shifts in wind patterns significantly influence the movement of soil particles between Sakiyama and Amitori bays on Iriomote Island, Japan. During summer, large particles remain near river mouths while smaller ones are transported eastward, whereas winter reverses this trend with large particles moving toward bay centers and small particles westward. Particle flow also shifts seasonally: from Sakiyama to Amitori Bay in summer but the opposite in winter. These dynamics, driven by wind speed, direction, and coastal topography, are critical for understanding sediment impacts on marine ecosystems, including coral reefs and seagrass beds (Enhalus acoroides). The study combines field observations with numerical simulations to provide insights essential for conservation efforts in these UNESCO-recognized natural areas.
