Prediction of dissolved gas supersaturation below spillways

David E. Hibbs, John S Gulliver

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Supersaturation of dissolved gases below spillways often occurs due to the hydrostatic pressure exerted on bubbles in the tailwater. As bubble depth increases, so does the pressure inside the bubbles as well as the saturation concentration. Dissolved gas levels below spillways tend toward these elevated saturation concentrations. A theory is developed for estimating an effective or weighted average bubble depth and a corresponding effective saturation concentration to be used in conjunction with existing dissolved gas prediction models.
