High-Performance Aerating Weirs for Dissolved Oxygen Improvement

New concepts in aerating weir design are being explored for improving dissolved oxygen in tailwaters downstream from hydropower projects with oxygen-deficient releases. Reliable design procedures are being developed from experiences of the Tennessee Valley Authority (TVA) and other utilities in a project sponsored by the Electric Power Research Institute (EPRI). The project includes laboratory and prototype field experiments to fill gaps in existing knowledge. This paper is intended to update water resources professionals on the project.
