Abstract:

An earlier effort to measure resuspension of sediment relied on U.S. standard depth-integrating sediment samplers. In designing a new effort to collect field data on resuspension, the advantage of obtaining samples at several points in a single vertical over the depth-integrated sampling procedure was recognized. The field installation includes ISCO pump samplers with intakes mounted at several distances above the river bed. Background samples are collected every hour. Vessel passage events trigger an intensive period of sample collection. Typical data are presented and discussed for a straight reach on the Illinois River during low flow in the fall of 1988.
