Liquid flow in open channels — Sediment in streams and canals — Determination of concentration, particle size distribution and relative density

In problems of sedimentation and sediment transport, a knowledge of the concentration and the characteristics of the sediment, such as particle size distribution and relative density, is of great importance. For this purpose, sediment samples are collected by suitable samplers and analysed in a laboratory. The results of the analysis are used in the calculation of sediment load, mean diameter and other characteristics.
