Abstract: This study concerns with an integrated simulation of coupled heat and mass transfer between bare soil and atmosphere. A model is constructed in one dimension from ground water table up to upper atmospheric boundary layer. Numerical solutions of momentum, heat and mass transport equations are available for prediction of physical processes occurring in atmospheric boundary layer and in porous bodies. The processes in the atmosphere and in the porous bodies are linking each other by a statement of heat and mass conservation. The water mass in the soil is treated as a two-phase mixture of liquid water and vapour. The simulated results are supported by the observation data recorded by a meteorological station placed in the experimental field in Hanno new resident town, Saitama prefecture. A good agreement indicates that the model is reliable for predicting a water budget dynamics in a zone near surface land and atmosphere.
