Prediction of Stream Reaeration Rates

Results are given of many field measurements of actual rates at which river water that is low in dissolved oxygen, but free of organic pollution, absorbs oxygen from atmosphere; by using dimensional analysis and multiple-regression techniques, observed reaeration rates have been related to hydraulic properties of river channels; several reaeration formulas thus developed can be used to predict accurately rate at which oxygen will be absorbed by water flowing in natural stream channels.
