The settlement rate of the larval Manila clam has increased by 28.9 times compared with still water when the steady flow acts on the infiltration flow at the same time. The settlement rate has increased by 5.1 times as the infiltration flow velocity 0.3cm/s increases from 0.01cm/s. Larval Manila clam accumulates in a high density on the surface of the sediments with comparatively rough particle size to which the tidal circulation of groundwater flow develops.
If the distribution density of the larval Manila clam, the particle diameter of the sediments, and the flow condition are understood, the settlement rate can be presumed based on this research.
