Deoxygenation in surface water of lotic environment

The mathematical models are gaining increasing importance in the evaluation and comparison of alternative management of natural water bodies. One of the difficulties of using models of water quality for oxygen is the absence of data on kinetic parameters of reactions of biochemical processes. This s...

description The mathematical models are gaining increasing importance in the evaluation and comparison of alternative management of natural water bodies. One of the difficulties of using models of water quality for oxygen is the absence of data on kinetic parameters of reactions of biochemical processes. This study aimed to evaluate the processes of temporal processing of oxygen in surface water of lotic environment. The study was conducted in the Meia Ponte River, Goiás, one of the main rivers of the state. Water samples were collected in the urban area of Goiânia, Goiânia New District 2, which shows apparent anthropogenic interference with the natural environment. After corrected to the standard temperature of 20°C, the BOD varied between 4.11 and 21.24 mg L-1 and during the process of biological oxidation, the deoxygenation coefficient (Kd20) varied from 0.12 to 1.05 d- 1, and an increase of organic matter in the dry season was observed.
