Effects Of Temperature On Moisture Conductivity In Unsaturated Soil, Richard O'Bannon Meeuwig May 1964

Effects Of Temperature On Moisture Conductivity In Unsaturated Soil, Richard O'Bannon Meeuwig

Water moves in soil in response to potential gradients. The basic equation for this movement is the generalized v=-K▽Φ in which v is volume of water passing through a unit area in unit time, K is the conductivity coefficient, ▽, is the gradient operator (vector), and ▽Φ is the potential gradient.

Teachers have noticed that children draw only those objects which they know by name. Doubtless the adult has a similar tendency, exemplified by the researcher, to limit his observations or to relate them to that which can be expressed in the terminology of an existing or newly developed theory. In this thesis the data obtained from studies of the temperature and pressure dependence of the relative vapor pressure over moist soil samples are analyzed by a thermodynamic approach. Not all of the results can be explained completely by means of this tool. Natural systems, such as a moist soil, are …
