HDRY
The head value that is assigned to cells that are converted to dry during a simulation.

HDRY 	= 9999 (for all layers)

---------------------------------------------------------------------------------------------------------------------
Ltype
0 = confined =  		Transmissivity and storage coefficient of the layer are constant for the entire simulation.
1 = unconfined =		Transmissivity of the layer varies. It is calculated from the saturated thickness and
						hydraulic conductivity. The storage coefficient is constant. This type code is valid only for layer 1.
2 = unconfined/confined=Transmissivity of the layer is constant. The storage coefficient may alternate
						between confined and unconfined values. Vertical flow from above is limited if the layer desaturates.
3 = unconfined/confined=Transmissivity of the layer varies. It is calculated from the saturated thickness
						and hydraulic conductivity. The storage coefficient may alternate between confined and unconfined
						values. Vertical flow from above is limited if the aquifer desaturates.

LAYTYP = 3 (for all layers)

---------------------------------------------------------------------------------------------------------------------
TRPY
is a one-dimensional variable containing a horizontal anisotropy factor for each layer. It is the ratio of
transmissivity or hydraulic conductivity (whichever is being used) along a column to transmissivity or hydraulic
conductivity along a row. Set to 1.0 for isotropic conditions. This is a single variable with one value per layer. Do
not read a variable for each layer—that is, include only one array control record for the entire variable. Note that
the LPF Package can be used to represent horizontal anisotropy that varies in magnitude within a model layer.

TRPY = 1 (for all layers)
---------------------------------------------------------------------------------------------------------------------
IWDFLG
0 	=	wetting is inactive
not 0 = wetting is active

IWDFLG	= 0 (for all layers)
