Abstract

Effects of the 1993 flood on river water and sediment quality were investigated using historical data and data collected from the Illinois River and Upper Mississippi River in a post-flood period. Overall the post-flood results showed systematic reductions and individual changes in the water and sediment constituents. The reductions in sediment metals and nutrients were most obvious at the Keokuk and Lock and Dam 26 stations. By analyzing and comparing the physicalchanges to the changes in water and sediment constituents at each station,it was found that physical processes such as sediment entrainment and, more importantly, the removal of fine sediment to be the main causes for the reduced concentrations in sediment constituents. On the other hand, sedimentredistribution and associated secondary contamination could have caused the emergence of several water and sediment constituents that were undetectedbefore the flood.
