Laboratory Studies of Segregation in Prograding Deltas of TSRU Tailings
Rochelle Widmer, Masters Candidate in Civil, Environmental, and Geo-Engineering
Advisor: Kimberly Hill, Associate Professor in the Department of Civil, Environmental and Geo-Engineering and St. Anthony Falls Laboratory, University of Minnesota
We studied the segregation and depositional behaviors of TSRU tailings, a fine-grained waste material produced in the Alberta Oil Sands refining process, toward the long-term goal of faster, more effective environmental restoration. The research used both surrogate material and real tailings material. We will briefly present similarities between the flow, segregation, and depositional behaviors of these two materials that have also been reported in other, natural prograding deltas, and also some distinct differences in the behaviors of the TSRU tailings relevant to environmental restoration issues.
