ZONEBUDGET in GMS
By alemon on January 19, 2012
GMS has an extensive tool set for working with flow budget information from MODFLOW. GMS is the only package that reports flow budget information on GIS features. For example, if polylines or polygons were used to create drain boundary conditions in MODFLOW then GMS will report the flow into or out of the model from the polyline/polygon. For some time now, GMS has allowed users to view flow budgets for selected sub-areas of their models as well as the ability to assign zone budget ids to cells and extract flow budget information.

Beginning with GMS 8.2, we will now include an interface to USGS ZONEBUDGET. This tool is accessed by selecting the Flow Budget menu command in the MODFLOW menu. There is a USGS ZONEBUDGET tab available in the dialog. The user can set up their input options and then there is a button to launch ZONEBUDGET. The input and output files for ZONEBUDGET are written to the same directory where the MODFLOW Cell-to-cell flow file is located.
There is also a new tutorial available that shows the various ZONEBUDGET options. Go to the GMS Learning Center on http://www.aquaveo.com/gms-learning to download the tutorial.
A video that demos the ZONEBUDGET feature is available on the Aquaveo youtube channel.
