Characteristics of Oxygen Production and Consumption in a Reservoir

Abstract

This paper deals with the production and consumption of dissolved oxygen caused by the behavior of algae and bottom mud in the reservoir. The amount of oxygen that produced by algae with photosynthesis and consumed with respiration, were obtained with field experiments. The relation between 0₂ production and water temperature, sunlight intensity were analyzed. The behavior of algae are shown to be characterized by optimal 0₂ production temperature, optimal sunlight intensity etc. Also 0₂ consumption by respiration and bottom mud is evaluated quantitatively. The validity of results was examined using 1-D water quality simulation of DO.
