Excerpt from Designs for Suspended-Load Samplers: Based Upon an Experimental Investigation of the Disturbances Caused by the Instruments and an Analysis of Sediment-Laden Flow
The amount of suspended solid material transported by stream.is usually determined by making sediment content and velocity measurements at many points in the cross section and integrating the results. The number of sampling points required will depend upon the degree of accuracy necessary, and, according to o'brien,l upon our knowledge of turbulent flow'and its relation to sediment trans portation.
