Geomorphology Study of Fargo, ND/Moorhead, MN Flood Risk Management Project (ND, MN)

The U.S. Army Corps of Engineers St. Paul District in cooperation with the Cities of Fargo, ND and Moorhead, MN have initiated a study to develop, evaluate, and compare flood risk management alternatives for the Red River of the North. WEST Consultants (WEST) will evaluate two diversion channel alternatives that have been proposed to manage flood risk for Fargo and Moorhead. A scientifically defensible study of the expected geomorphic impacts and sensitivity is being conducted by WEST for the two diversion channel alternatives. Physical modifications to the channel and floodplain and the use of diversion channels may interrupt or change ongoing geomorphic processes. Similarly, geomorphic processes could potentially affect the function and effectiveness of the proposed flood risk management project.

The geomorphic study includes approximately 200 miles of the Red River of the North, 87 miles of the Sheyenne River and Sheyenne River Diversion Channel, 43 miles of the Wild Rice River, 9 miles of the Rush River, 7 miles of the Lower Rush River, 13 miles of the Maple River, 3 miles of the Buffalo River, and 4 miles of Wolverton Creek.

The study will document and evaluate existing erosion conditions along the study reaches and will be used to predict the magnitude of changes in the erosion conditions as a result of the proposed diversion alternatives.
