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.
