Dissolved oxygen is oxygen gas that is entrained in the water as a result of water mixing with air containing oxygen. Different types of water bodies contain different amounts of dissolved oxygen.

A fast-flowing river usually contains more dissolved oxygen than a slow-moving one because it mixes rapidly with air containing oxygen while moving.Traveltime, reaeration, and water-quality characteristics during low-flow conditions in Wilsons Creek and the James River near Springfield, Missouri / (Rolla, Mo.: Dept.

Division of Environmental Quality.During low-flow conditions, dissipation of potential stream energy by log steps amounts to 6 percent, approximately equal to that by falls.

There are no statistically significant differences regarding spatial distribution of log steps between study basins with contrasting silvicultural and natural stream inputs of large woody debris.
