Simulation and field validation of heat and water flow during soil freezing and thawing

Creator:

Pikul, Joseph Lawrence

Abstract:

Freeze/thaw cycles are numerous in agricultural soils of the Pacific Northwest. Potential loss of soil by erosion is high whenever a soil thaws from the surface creating a saturated soil overlying an impermeable frozen layer. Field studies were conducted to investigate the effect of surface residue on soil freezing. Residue...
