Liquid flow in open channels. Sediment in streams and canals. Determination of concentration, particle size distribution and relative density Ingestion-build-232773 Poor sampling practices create problems

Poor sampling practices create problems for those interpreting results and can lead to costly and incorrect decisions

Preparation of specimens of given height and/or at a predetermined density

That’s why we’ve recently published BS 8243:2010+A1:2014 which offers recommendations on the installation

Liquid flow in open channels. Sediment in streams and canals. Determination of concentration, particle size distribution and relative density Ingestion-build-232773 Poor sampling practices create problems1 Scope 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
