Quality-assurance plan for the analysis of fluvial sediment by laboratories of the U.S. Geological Survey

This report describes procedures used by the Iowa District sediment laboratory of the U.S. Geological Survey to assure the quality of sediment-laboratory data. These procedures can be used by other U.S. Geological Survey laboratories regardless of size and type of operation for quality assurance and quality control of specific sediment-laboratory processes. Also described are the equipment, specifications, calibration and maintenance, and the protocol for methods used in the analyses of fluvial sediment for concentration or particle size.

Fluvial sediment data for Iowa—Suspended-sediment concentrations, loads and sizes; bed-material sizes; and reservoir siltation

This report is a compilation of the fluvial sediment data collected and published by the U.S. Geological Survey and other Federal agencies for the State of Iowa. The compilation includes daily extremes, monthly summaries, particle-size analyses of suspended-sediment, particle-size analyses of bed materials at some daily suspended-sediment stations, suspended-sediment concentrations and loads for samples collected at periodic and miscellaneous sites, and reservoir sedimentation studies on streams.
