This study aims to reveal the effect of sediment grain-size sorting by velocity variation of flows that contain abundant suspension. Grain-size analysis of natural deposits suggested that sediments deposited from suspension generally show remarkable variation in their fractions of coarser grain-size classes whereas they are relatively stable in fractions of finer grain-size classes. Numerical calculation reproduce tendency described above, and confirmed that the sensitivity of grain-size sorting is higher in coarse-grained sediment than finer sediments. Future investigation may indicate that mode of grain-size sorting can be a clue to reconstruct paleo-hydraulic conditions from strata.
