A2: Argo Dam

In the blogs section of “Erosion Control,” which is the journal of the International Erosion Control Association, Ann Arborite Donald Gray has published an analysis of Argo Dam removal that focuses on how river channels can be affected when dams are removed.  Gray is an emeritus University of Michigan professor of civil and environmental engineering.

Among the conclusions of Gray’s analysis: “If the dam is removed, the river will attempt to reoccupy its old channel. Views of the entrance to the original channel, including a thin sheet-pile wall constructed across the entrance, are shown in Figures 3 and 4. Absent Argo Dam, this wall would either be overtopped, flanked, and/or toppled during a high-water flood event. This would result in flooding and inundation of the MichCon service center and surrounding areas.” [Source]
