ISO 4365:2005 specifies methods for determining the concentration, particle-size distribution and relative density of sediment in streams and canals.
The detailed methods of analysis are given for the following:
determination of the suspended sediment concentration by evaporation and filtration;
particle-size analysis of suspended sediment;
determination of the bed-load and bed material sediment;
determination of the relative density of sediment;
determination of particle-size distribution characteristics.
