The MT3D Transport Observation Package dialog.

The Transport Observation Package (TOB) calculates simulated concentrations associated with observation points and mass flux associated with MODFLOW boundary conditions. The dialog is reached through the Transport Observation Package command in the MT3DMS or MT3D-USGS menus.

The concentration observations may be from observation points. The observations are specified in coverages in the map tools within GMS. Coverages selectd in this dialog will be used by the package.

The package can also compute a mass flux associated with a group of MODFLOW boundary conditions. For example, if a contaminant plume migrates to a river this package can compute a mass flux into the river. This is similar to the flow observation groups that are created in MODFLOW models.
