Abstract:In permafrost areas, the analysis of soil thermal and hydraulic regimes is complicated by phase change effects and by moisture migration. During freezing, mobile soil moisture is drawn toward the freezing front, increasing the available latent heat; therefore, it is critical particularly in unsaturated soils, that moisture transport and soil water phase change be correctly simulated by computer modeling. The moisture transport is affected by soil moisture tension and hydraulic conductivity, as well as by soil thermal regime, implying that moisture transport and soil temperatures are strongly coupled.
