Gas transport in a residual layer of a water basin
The transport of gases forming in the sedimentary (active) layer of water basins and coming from the atmosphere is discussed. Diffusion equations are used to derive differential equations describing a change in the concentrations in the sedimentary layer with depth. The asymptotic equations describing a change in gas concentration with active layer depth have been derived. It is shown that the rate of gas generation (W) and the position of the upper boundary of bubbling (h) are related via the relationship W∼h−2. A comparison has been made with experimental data.
