A series of numerical analyses has been carried out to investigate the sensitivity of water content, pore-water pressure and temperature changes to the variations of the soil albedo value (i.e., the ratio of reflected to incident solar radiation) and the initial temperature profiles (ITP). The soil-atmosphere interface model is used to calculate the evaporation rate and heat flux on the soil surface; the water transport equations (liquid - Darcy's law and vapor - Fick's law) coupled to heat flow equation (de Vries 1987) are solved to determine the profiles of temperature, water content or pore water pressure. The results show that it is important to know the atmospheric water balance for predicting soil temperature and water content (or pore water pressure) profiles. The results also suggest that the ITP can affect the temperature profiles but its influence of the considered changes on the pore water pressure and volumetric water content profiles is very small. During the cold season, precise albedo values are not very important nor very sensitive in influencing the water balance.
