Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (pages 13-14). "Sampling for sediment associated nutrients and contaminants in rivers requires collection of suspended sediment samples. Sediment agencies typically collect through the vertical water column where as water quality agencies typically collect samples near the surface of the water column. This paper examines the distribution statistics of surface samples relative to samples taken through the vertical section. The objective is to provide an estimate of error associated with near-surface sampling of the silt and clay fractions of the suspended sediment load in rivers"--Management perspective.
