Benchmark Sediment Monitoring Program for Illinois Streams : Data Report for Water Years 1998 and 1999

The Benchmark Sediment Monitoring Program for Illinois Streams was initiated by the Illinois State Water Survey in 1981 to generate a long term database of suspended sediment concentrations and instantaneous sediment loads. The program is now part of the Water Survey’s Water and Atmospheric Resources Monitoring (WARM) Network, which monitors climate, soil moisture, surface water, groundwater, and sediment throughout Illinois. This report summarizes the suspended sediment data collected for the program during Water Years 1998 and 1999. All the techniques used in the data collection process and laboratory analyses are based on U.S. Geological Survey procedures and techniques. The report appendices present tables of instantaneous suspended sediment measurements, particle size analysis, sediment transport curves, and plots of instantaneous sediment concentrations for the period of record for the current monitoring stations.Ope
