• Winter soil water dynamics: Completion report

      Kane, D. L. (University of Alaska, Institute of Water Resources, 1975-12)
      The movement of soil moisture through cold regions soils is an active process that continues throughout the year. It represents one mechanism of heat transport in subsurface soil, conduction being the main mode of heat flow. In frozen soils, this moisture may undergo phase change resulting in two significant events: 1. deformation of the near-surface layer, and 2. liberation or uptake of heat at the point of phase change. Where deformation (induced by either frost heaving or thaw consolidation) occurs in man-made embankments, it is readily apparent at the surface. Restoration of the deformed surface requires large sums of money.
