! When selecting the shallow water table option (WT) the inputs below are used:
! ITHETATYPE is an integer to select the soil water characteristic curve
! type with values: 1=van Genuchten, 2=Brooks and Corey.
! Note that SAV and OI are now calculated internally, but some dummy numbers 
! must be included to ensure backwards compatibility, even although these 
! numbers are ignored by the program when the WT option is selected.
! Equation   ITHETATYPE PAR1 PAR2     PAR3    PAR4
! van Genuchten 1       OR   VGALPHA  VGN     VGM
! Brooks&Corey  2       OR   BCALPHA  BCLAMBDA --

! IKUNSTYPE is an integer to select the unsaturated hydraulic conductivity 
! curve type with values: 1=van Genuchten, 2=Brooks and Corey, 3=Gardner

! Also, Ks (m/s) is read as part of the common soil properties in ISO (VKS).
