Extensive field data on various aspects of physical effects of navigation within the UMRS are being collected and analyzed. The data acquisition program developed by the Illinois State Water Survey (ISWS) uses automated data logging systems for data collected with a number of measuring instruments, including current meters, electronic wave gages, wind monitors, turbidity meters, and pressure transducers. Suspended sediment is collected by a series of continually pumped sampling systems.
