Abstract: A theory was developed and tested to predict the distribution of flow among multiple ports in a density stratified fluid (e.g. a thermally stratified reservoir). Knowledge of the individual port flows is necessary to accurately estimate the release water characteristics using current selective withdrawal technology. The comparisons between the predictions and observations encompass a wide range of intake structure sizes, port configurations, and flow rates. The comparisons were favorable with the only significant errors limited to an unlikely range of operating conditions. For a large percentage of potential flows, the resulting stratified-flow-distribution algorithm can predict, with reasonable accuracy, the individual port flows and the desired water quality constituents. This has been incorporated into a subroutine for inclusion in numerical reservoir models.
