Free surface and saturated-unsaturated flow models are applied to the problem of constant head borehole infiltration tests for determining saturated hydraulic conductivity above a water table. The free surface model follows the same general approach employed to develop analytical solutions, but this model does not suffer from some of the many simplifying assumptions regarding boundary conditions. Nonetheless, the results of steady state simulations with the free surface model agree rather well with the analytical solutions. -from ASCE Publications Abstracts
