Abstract
Owners of hydropower facilities face increasing demands to reduce or eliminate environmental concerns arising from the impoundment and control of once-natural stream flows. These demands, which are rooted in a complex mélange of technical, political, social, legal, and economic factors, are typically applied through regulatory criteria for mitigating the impact of hydro projects on aquatic habitat. The improvement of low dissolved oxygen (DO) in reservoir releases is a major environmental concern for projects with moderate to heavy amounts of organic sediments. When applicable, turbine aeration often is the most cost-effective technology for providing DO improvements. However, opportunities to solve DO-related water quality problems by turbine methods are often overlooked. In some cases this is due to ambiguous accountability for the low DO problem. In other cases, it is due to limited awareness of aerating turbine capabilities, limited support for research and development, or a lack of industry-accepted procedures for the analysis and design of these turbines. This paper presents a brief summary of guiding principles used for justifying, specifying, and
