Hatcher defines SOD (Sediment oxygen demand) as "the rate at which Dissolved Oxygen (DO) is removed from the water column due to the decomposition of organics in the bottom sediment". "after a river is polluted, the pollutant gradually deposits to pollute the sediment, and the polluted sediment further affects the quality of the upper water, and the polluted sediment can cause the consumption of the dissolved oxygen in the upper water body to be accelerated. Especially for rivers and lakes polluted by organic matters, the organic content in the water bodies is higher, and the consumption of the sediments on oxygen is more remarkable. In some previous studies scientists found that SOD in some rivers has a greater specific gravity for the total oxygen consumption in the body of water.
