The CHOB package is used to compare observed flows at specified head cells 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 CHOB package is only possible if the CHD package is activated. Once activated, the user can enter comments regarding the CHOB package. The observations of flow at specified head 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.
