Introduction
Infiltration into the vadose zone is typically studied under conditions that do not consider poreair entrapment. Pore-air generally does not impede infiltration rates or wetting front movement when the water table is at depth. Siemens et al. (2014) considered the impedance of water infiltration due to pore-air in a closed soil system using both laboratory and numerical experimentation. An example of a closed system is a shallow soil profile with a near surface noflow boundary, such as a low conductivity soil layer or bedrock surface. This example compares infiltration into an unsaturated soil column for the open and closed conditions. The open condition means that the soil is able to accept infiltration with no pore-air entrapment, while a no-flow boundary prevents pore-air from escaping the column in the closed system.
