The GBOB package is used to compare observed flows at general head boundaries with simulated flows computed by MODFLOW. The pane for this package is on the MODFLOW Packages and Programs dialog box under Observations.
Checking the checkbox associated with the GBOB package is only possible if the GHB package is activated. Once activated, the user can enter comments regarding the GBOB package. The observations of flow at general-head boundary cells are specified in the Manage Flow Observations dialog box.
The MODFLOW Listing file will contain a list of the observed values and the simulated equivalents.
