Illinois Benchmark Network Instream Suspended Sediment Monitoring Program, Water Year 1986

摘要

Beginning in Water Year 1981, the Water Survey's suspended sediment monitoring program evolved from the effort to gather data on sediment transport and sedimentation in Illinois waterways. In Water Year 1981, the program consisted of 50 stations throughout the state. However, by Water Year 1983 a series of cuts in funding reduced the number of stations to 18. In 1983, the suspended sediment monitoring program was combined with two other Water Survey monitoring programs under the program name of the Illinois Benchmark Network (IBN). Since that time, the IBN has continued to maintain suspended sediment stations statewide. The report, which presents the suspended sediment data collected during Water Year 1986, is a continuation of the Water Survey's Circular 171 series presenting data collected in the suspended sediment monitoring program. In Water Year 1986, 16 stations were maintained. All the techniques used in the data collection process and the laboratory analyses were based upon those used by the U.S. Geological Survey. All the data for Water Year 1986, including those pertaining to water discharge, sediment concentration, sediment load, and particle size distribution of the suspended sediment samples, are given in the appendices to the report. The appendices also include the statistical parameters for the regression equations relating water discharge and suspended sediment load data for Water Year 1986.
