The finite difference flow and transport simulator VS2DT was benchmark tested against several other codes which solve the same equaltions (Richards equation for flow and the Advection-Dispersion equation for transport). The benchmark problems investigated transient twodimensional flow in a heterogeneous soil profile with a localized water source at the ground surface. The VS2DT code performed as well as or better than all other codes when considering mass balance characterisitcs and

Following the benchmark study, the code was verified against two analytical solutions, one for two-dimensional flow and one for two-dimensional transport. These independent verifications show reasonable agreement with the analytical solutions, and complement the one-dimensional verification problems published in the code's original documentation.
