The steady‐state flow of gases in soils is analyzed mathematically from the view of land disposal of waste gases. Gas injection systems considered include ditches, buried pipes, and wells. The systems are compared on the basis of two criteria (i) how effectively the power is used (power efficiency), and (ii) how uniformly is the gas distributed through soils (uniformity). Often the two criteria are in conflict, and systems giving a high power efficiency result in low uniformity. Gas injection by buried porous pipe appears advantageous over ditch or well systems.
