Water-resources planning and water-quality assessment require a nationwide database of relatively standardized information. Sediment concentration and discharge in Missouri's rivers and streams need to be defined and monitored.
Provide sediment data for use in comprehensive State and Federal planning and action programs, including State and Federal management of interstate and international waters.
A network of sediment stations is operated to provide spatial and temporal averages and trends of sediment concentration, sediment discharge, and particle size of sediment transported by rivers and streams.
Bed-material samples are often collected from a boat by using a US BM-54 sampler. (*)

Data are being collected at eight suspended-sediment data sites and five partial record suspended-sediment sites during 1996. The sediment samples collected at these sites will be analyzed for concentration, particle size, and distribution at the U.S. Geological Survey laboratory facilities in Rolla, Missouri. The District Sediment Lab also analyzes samples from other USGS districts and in the 1995 water year more 7,300 analyses were conducted.
Suspended-sediment samples may be collected by using a US P-63 sampler suspended from a specially designed boom-hoist car. (*) (88k GIF) A US P-63 sampler
