Design of a dam sediment management system to aid water quality restoration of the Chesapeake Bay

摘要: The water quality of the Susquehanna River, a major freshwater tributary Chesapeake Bay, significantly affects aquatic health Bay. Following storms in which river flow rate exceeds 300,000 cubic feet per second (cfs), nutrients and sediment stored Lower Reservoir are deposited into These excess facilitate algae blooms that hinder growth sub-aquatic vegetation (SAV) harm Bay's species. Conowingo Dam, on is estimated to be at 85% its capacity. To reduce backlog, three dam management alternatives have been identified: (i) No Mitigation, (ii) removal by Hydraulic Dredging (iii) increasing bottom shear velocity avoid build-up. A utility analysis conducted using fluid mechanics, ecological impact business model indicates annual 5,000,000 yards produce slag product, with instantiation diverter increase stress best alternative.
