The Gloryhole Approach to Increasing Dissolved Oxygen Content

by Kenneth R. Broome, Williams and Broome, Inc, Reading, United States,



Document Type: Proceeding Paper

Part of: Waterpower '91: A New View of Hydro Resources

Abstract:

Deep intakes at hydroelectric dams in southern states withdraw water that is oxygen deficient during summer months when reservoirs become stratified. The 'Gloryhole' approach to solving this problem uses a funnel(s) of stiffened geotextile fabric suspended from a buoyant ring(s) to withdraw water from surface strata that are usually much richer in oxygen content. The bottom of the funnel(s) is (are) fastened around the intake(s) to the hydroelectric plant, thus replacing oxygen deficient bottom water with oxygen rich surface water. This paper explains the concept and how it could be installed at a hydroelectric plant such as the one at the U.S. Army Corps of Engineers Richard B. Russell Dam in Georgia. Projected capital cost estimates and operating costs are included together with expected operating and maintenance requirements. A suggested program of development and testing concludes the paper.
