Instability of the salinity profile during the evaporation of saline groundwater [PDF]
, 2008 We investigate salt transport during the evaporation and upflow of saline groundwater. We describe a model in which a sharp evaporation-precipitation front separates regions of soil saturated with an air-vapour mixture and with saline water.

On the measurement of air permeability.
Netherlands Journal of Agricultural Science, 1987 Air pemeability values are used to assess the state of aeration, soil structural stability, structural degradation and compaction. A simple experimental procedure, using a constant-speed motor, a syringe and simple pressure sensors, is discussed. At steady-state air flow throught a soil sample the air permeability coefficient can be derived directly ...
