AbstractSoils composed of minerals having the same refractive index as water are translucent when saturated. Any air in the pores is fully visible. Such soils have been used to observe the manner in which air may replace water in soil pores. Where the external air and water pressures are established such as to cause rapid drainage of water, the air suddenly spreads through the pore structure at a certain air/water pressure difference. Where drainage occurs more slowly, a progressive diffusion of air in solution occurs, giving enlargement of bubbles, as well as a progressive breakdown of menisci not easily explainable from capillary theory.
