Predicting Dissolved Oxygen and Nitrogen Uptake During Turbine Aeration

摘要

During hydropower production, stratification of the upper reservoir can result in exceedingly low levels of dissolved oxygen (DO) a distance below the water surface. In many sites, water from these depths enters the turbine intakes where it is transported to the tailwaters downstream of the plant. There, low levels of dissolved oxygen can have an adverse effect on aquatic life and water quality. In an effort to reduce the environmental impact of hydropower generation, governmental regulations are being established which require minimum tailwater DO concentrations.
