The objective of this thesis is to investigate regional differences and similarities of sediment discharge in relation to streamflow in the Illinois River Basin. Sediment deposition has been a persistent problem in the Illinois River System: it degrades the aesthetic quality of the river, makes commercial shipping difficult and fills in the backwater lakes. The investigation was conducted on two scales 1) the event scale and 2) the study-period scale. Twelve U.S.G.S. stream gaging stations found within the Illinois River Basin were used in this analysis. The study period was April 1 through August 31 of 1981. The data collected were average daily values of sediment discharge and streamflow. The event scale analysis brought out greater differences between the Illinoian Age and the Wisconsinan Age subbasins that comprise the Illinois River Basin. Based on the results of this investigation the most significant factor that influences the sediment discharge-streamflow relationship in the Illinois River Basin is probably surficial geology.
