Physical impacts of navigation: Ohio River field data collection

This report summarizes the data collected by the Illinois State
Water Survey from the Ohio River to determine the physical impacts
of navigation.  The Louisville District of the U.S. Army Corps of
Engineers initiated the field project on the Ohio River in which
various physical, chemical, and biological data were collected in
connection with the movement of tows with barges.  The Illinois
State Water Survey participated in the collection of physical data
with respect to barge traffic.  Barges with tows of varying
horsepower were rented by the Corps of Engineers and navigated up
and down the Ohio River at predetermined frequencies at the test
site.  This experimental river traffic was controlled as to speed,
direction, and frequency.  The following physical impacts data
were collected by Water Survey engineers and scientists:   a)
nearshore velocity structure: magnitude, direction change, and
turbulence intensity; b) wave characteristics:  amplitude, period,
duration, and relative magnitude; and c) resuspension of sediment: 
point and depth-integrated suspended sediment samples were
collected within the channel border area for determination of
sediment concentration and particle size distribution.  No
analyses of the data have been performed for this report.
