Describes methods for determining the concentration, particle-size distribution and relative density of sediment in streams and canals.

This International Standard specifies methods for determining the concentration, particle-size distribution and relative density of sediment in streams and canals.

NOTE The detailed methods of analysis are set out in the annexes. Annexes A, B and C deal with the determination of the suspended sediment concentration by evaporation and filtration. Annexes D and E deal with the particle-size analysis of suspended sediment and outline the procedures for the bed-load and bed material sediment, respectively. Annex F deals with the determination of the relative density of sediment and Annex G with the determination of particle size distribution characteristics.
