A flood risk management existing conditions hydraulic model is a tool which can be used to more accurately evaluate and communicate flood risks, as well as explore mitigation strategies to reduce future risk. It can also help provide better predictability and more consistent flood risk management.
Development of a standardized and seamless flood risk management hydraulic model for the Upper Mississippi River System (UMRS) is an essential part of understanding the risks that currently exist to the river communities. It is a critical first step to support development of a systemic flood risk management strategy.
As part of this effort, the Corps of Engineers developed a new, updated hydraulic model for the Upper Mississippi River System, including the Illinois Waterway. This collaborative effort involved a variety of state and federal agencies, is facilitated by the Corps of Engineers Rock Island, St. Louis and St. Paul districts and uses the Hydrologic Engineering Center's River Analysis System (HEC-RAS).
