...For all material types, SWCC and SPCC functions were determined using the Equations 1 and 2 as explained earlier....
...The input parameters required for the development of a model in VS2DI include: (1) geometry, that is, slope and thickness of the layers; (2) initial conditions, that is, ground water table (GWT) and maximum negative pressure head; (3) boundary conditions, that is, rainfall duration and infiltration rate; (4) basic hydraulic properties of the material, such as porosity and saturated permeability; and (5) unsaturated hydraulic characteristics, that is, soil water/permeability characteristic curves (SWCC and SPCC)....
