Upper Mississippi River System Hydraulic Model Update Complete

Upper Mississippi River System Hydraulic Model Update Complete,

The U.S. Army Corps of Engineers, Rock Island, St. Paul and St. Louis districts recently completed a seven-year effort to develop an updated, standardized hydraulic model for the Upper Mississippi River System, including the Illinois Waterway. The model can be used to evaluate and communicate the effects of floodplain modifications to provide better predictability and more consistent flood risk management for the Upper Mississippi River System.
