TWO DIMENSIONAL FLOW MODEL WITH APPLICATION TO NEAR SURFACE WATER MOVEMENT IN COLD REGIONS
A two-dimensional flow model was developed to predict flow in this shallow, layered system. A finite difference solution of the equation for transient flow of water due to hydraulic gradients was utilized based on the alternating-direction-implicit technique. This model has been applied to a shallow two-layered system with an organic soil over a mineral soil. A comparision of the nature of flow for various ratios of hydraulic conductivity for the two soils was made. These results are useful in understanding the nature of surface runoff generated in soils overlying shallow permafrost as well as in the evaluation of the potential of groundwater recharge from either snowmelt or rainfall in settings with seasonal frost.
