Abstract:Physical changes associated with navigation traffic in a large river environment such as the Illinois or Mississippi River are many and varied. Some of these changes are related to basic hydraulic and physical factors, and can be measured using available instrumentation. Other changes are not quantifiable by direct measurement in the field, and their effects can only be observed over a long period of time. Relationships between barge-tow movements and the hydraulic and physical characteristics of specified reaches of a river are not fully understood at the present time. This scientific area of large river fluvial hydrodynamics has not been addressed fully with a detailed and comprehensive plan of action. Moreover, because changes in the hydraulic parameters of a river are normally associated with changes in the river's biological activities and/or habitats, a clear understanding of the ambient or original hydrauliccharacteristics of the river is needed before management decisions can be made. The present investigation is one of the first attempts to quantify the hydraulic changes associated with the movement of navigation traffic within the Upper Mississippi River System (UMRS). Work is also being done by researchers from the Waterways Experiment Station (U.S. Army Corps of Engineers) on laboratory simulation of flows in the near field of a barge-tow. This report outlines the research that has been completed by engineers and scientists from the Illinois State Water Survey (ISWS) on physical changes associated with navigation traffic. In addition to research results, materials showing the basic hydraulic structure of large river systems such as the UMRS are included in the appendices.
