摘要：
The flow of water through unsaturated soil is based on extension of Darcy's law. The finite difference techniques are used to solve the model for evaluation of variations of hydrological and thermal variation due to flow of water into the soil. The pedotransfer function for estimating the soil properties is further used as input to simulate the problem domain. The validation of simulated result, based on transient heat conduction equation, is carried out. Further, the second-order upwind and QUICK methods are used to compare the thermal simulated results. The simulation results for variation of moisture content, the matric potential, and hydraulic conductivity with respect to rig linear dimension variation are further presented.
