... test is underway in which a section of a deep underground tunnel is filled with groundwater and the existing desaturated zone with trapped air is subjected to high water pressure. Water saturation in the unsaturated zone as a function of capillary pressure is well understood. However, the process...

A numerical model was developed to understand the mechanism controlling gas flow, which was found to be the relative buoyancy of the gas phase within the dump compared with atmospheric air. Changes in atmospheric air density are caused by atmospheric temperature variations, whereas dump gas-phase...
