VAM2D Overview
VAM2D (Variably Saturated Analysis Model in Two (2) Dimensions) is a two-dimensional finite-element groundwater model that simulates transient or steady-state groundwater flow and contaminant transport in porous media. VAM2D analyzes unconfined flow problems using a rigorous saturated-unsaturated modeling approach using efficient numerical techniques. Accurate mass balance is maintained in VAM2D even when simulating highly nonlinear soil moisture relations. Hysteresis effects in the water retention curve can also be simulated. A wide range of boundary conditions can be treated in VAM2D including seepage faces, water-table conditions, recharge, infiltration, evapotranspiration, and pumping and injection wells. The contaminant transport option can account for advection, hydrodynamic dispersion, equilibrium sorption, and first-order degradation. Transport of a single species or multiple parent-daughter components of a decay chain can be simulated. The VAM2D code can perform simulations using an areal plane, cross section, or axisymmetric configuration.
