Abstract: The authors present the results of recent selective withdrawal research in the form of a general mathematical description of this stratified flow phenomenon. A new description for boundary interference, which often impacts the formation of the withdrawal zone, was explicitly included in the mathematical formulations. These results were incorporated into the computer code SELECT, a numerical model of withdrawal from a stratified impoundment. The authors present an example of model application to provide guidance on outlet structure operation for maintenance of release water quality.
