Temperature effects on capillary pressure in unsaturated soil

Abstract

Subsurface temperature is generally affected by the natural trend of steady upward flux of heat from the interior of Earth Temporal fluctuations of surface air temperature and sustained effect of it over ground surface produce temperature anomaly up to a certain depth of subsurface Subsurface temperature can affect the soil water flow through the temperature derivative of capillary pressure or temperature coefficient thereby signifying the effects of existent temperature gradient in the s
