Ambient suspended sediment concentration and turbidity levels


Publication Date


The temporal variation of suspended sediment concentration and turbidity is an important component of the riverine environment. The maximum rate of discrete volumetric sample collection for laboratory determination of sediment concentration is one sample per minute for our field data collection on the effects of navigation on the Upper Mississippi River System. In an effort to obtain truly continuous measurements, another set of intakes and pumpers was used to obtain and record continuous turbidity data while discrete samples were being collected. Ambient suspended sediment concentration samples and turbidity values were collected continuously for a three-hour period to measure variability over time. A turbidity-concentration correlation [...]
