| Abstract: | A theory of silt settling in layers of size groups is put forward.The relation between the settling velocity of the layers and the natural settling velocity is determind.Correlations between the true and measured sizes for coarse particles are set up;and the cumulative percentage of fine particles for all particles is checked with the experimental data.A theoretical backgroungd for correction of the measured size gradation by using the Settling Tube Method for size analysis of fluvial sediment samples is provided. |

| Keywords: | particle size apparatus silt group settling interrelation of particle size percentage interrelation |
