Vertical distribution of fine grain sediments have been observed during floods by using a specially designed sampler at the Abukuma River mouth. The samples were analyzed through the Coulter Counter to obtain the grain size distribution. For each grain size range, the observed vertical distributions of the concentration are compared with Rouse's solution. The reference concentration at 5% of the depth from the bottom extrapolated by the solution are compared with Lane's formula using the grain size distribution of the bed materials which was also taken during the flood. Also the relationships between the reference concentration and discharge for each grain size range are presented.
