Changees to model parameters in order to simuulate connective cracking above undergroound mines has been
undertaaken manuallyy. Shapefiles were createdd delineating zones
z
where changes
c
were required. In order to
do this the shapefilees need to be imported as m
maps. Once the
t file is prepared it can bbe imported using the
menu FFile > Map > Shapefile.... The file musst then be seleected. Grounddwater Vistas will then use this file
to produce a file in itts own format (.map). A nam
me for this filee must be provvided.

meters can be changed

Once m
model setup iss finished, the model inputss need to be translated
t
to MODFLOW innput files form
mat. This
operation is done pressing the

atasets.
With thhe model filess translated, thhe model can be set to run wither using Groundwaterr Vistas or witth native
USGS M
MODFLOW thrrough the com
mmand promptt.
From Groundwater Vistas,
V
the moddel can be runn using the meenu Model > MODFLOW > Run MODFFLOW. A
new dialog will apppear showing the running pprogress and verbose messages. The m
model should carry

At this point it will say the

Modflow has finished and model results will be ready to be post-processedd.
