UPW PACKAGE FLAGS
Blossum Groundwater Availability Model v1.01
---------------------------------------------------------------------------------------------------------------------
HDRY
The head value that is assigned to cells that are converted to dry during a simulation.

HDRY 	= -9.999000e+03 (for all layers)

---------------------------------------------------------------------------------------------------------------------
IPHDRY
is a flag that indicates whether groundwater head will be set to HDRY when the groundwater head is less than 1×10-4 above the cell 
bottom (units defined by LENUNI). If IPHDRY=0,then head will not be set to HDRY.If IPHDRY>0,then head will be set to HDRY.

IPHDRY 	= 0 (for all layers)

---------------------------------------------------------------------------------------------------------------------
LAYTYP
0 = 	confined
>0 	= 	convertible between confined and unconfined
<0 	= 	convertible unless the THICKSTRT option is in effect. When THICKSTRT is in effect, a negative value of
		LAYTYP indicates that the layer is confined, and its saturated thickness will be computed as STRT-BOT.

LAY 1 LAYTYP = 1
LAY 2 LAYTYP = 2
LAY 3 LAYTYP = 2

---------------------------------------------------------------------------------------------------------------------
CHANI 
contains a value for each layer that is a flag or the horizontal anisotropy. If CHANI is less than or equal to 0, 
then variable HANI defines horizontal anisotropy. If CHANI is greater than 0, then CHANI is the horizontal anisotropy 
for the entire layer, and HANI is not read. If any HANI parameters are used, CHANI for all layers must be less than 
or equal to 0.

LYR 1 CHANI	= 1.000000e+00
LYR 2 CHANI	= 1.000000e+00
LYR 3 CHANI	= 1.000000e+00
---------------------------------------------------------------------------------------------------------------------
LAYVKA
contains a flag for each layer that indicates whether variable VKA is vertical hydraulic conductivity or
the ratio of horizontal to vertical hydraulic conductivity.
0 =		indicates VKA is vertical hydraulic conductivity
not 0 =	indicates VKA is the ratio of horizontal to vertical hydraulic conductivity, where the horizontal hydraulic
		conductivity is specified as HK in item 10.

LYR 1 LAYVKA = 0
LYR 2 LAYVKA = 0
LYR 3 LAYVKA = 0
---------------------------------------------------------------------------------------------------------------------
LAYWET
contains a flag for each layer that indicates whether wetting is active. LAYWET should always be zero for the UPW 
Package because all cells initially active are wettable.

LYR 1 LAYWET	= 0
LYR 2 LAYWET	= 0
LYR 3 LAYWET	= 0
