The Unsaturated Zone Flow (UZF) dialog

The Unsaturated Zone Flow (UZF) Package dialog is accessed by double-clicking on the WEL package under a MODFLOW 6 simulation in the Project Explorer. It contains the following sections and options:

  • Sections list – A list of sections that can be turned on or off:
    • Comments – Turn on to make the Comments section visible.
    • Options – Turn on to make the Options section visible.
    • Data – Turn on to make the Data section visible. This section is on by default.
  • Comments section – Enter general alphanumeric comments. Comments entered here get written at the top of the file, preceded by a '#' symbol.
  • Options section – Temporal options and settings:
    • Auxiliary Variables... – Click to bring up the Auxiliary Variables dialog.
    • Time Series... – Click to bring up the Time Series Files dialog.
    • Observations... – Click to bring up the Observation Files dialog.
    • AUXMULTNAME – The name of the auxiliary variable.
    • BOUNDNAMES – If turned on, indicates that the list of UZF cells will be provided with the associative boundary names.
    • PRINT_INPUT – If turned on, indicates that the list of UZF information will be written to the listing file after it is read.
    • PRINT_FLOWS – If turned on, indicates that a list of UZF flow rates will be printed to the listing file.
    • SAVE_FLOWS – If turned on, indicates that the UZF flow terms will be written to a specified file.
    • BUDGET FILEOUT – Allows the specification of a file to which desired flow terms will be written.
    • MOVER – When turned on, indicates that the Unsaturated Zone Flow (UZF) Package, in this instance can be used in collaboration with the Water Mover (MVR) Package.
    • SIMULATE_ET – If turned on, this indicates that ET will be simulated.
    • LINEAR_GWET – If turned on, indicates that groundwater ET will be simulated.
    • SQUARE_GWET – If turned on, indicates that groundwater ET will be simulated by assuming a constant ET rate.
    • SIMULATE_GWSEEP – If turned on, indicates that groundwater discharge to land surface will be simulated.
    • UNSAT_ETWC – If turned on, indicates that ET in the unsaturated zone will be simulated as a function of the specified PET rate.
    • UNSAT_ETAE – If turned on, indicates that ET in the unsaturated zone will be simulated simulated using a capillary pressure based formulation.
  • Data section – Contains the following:
    • Periods drop-down – Use the Increment Up and Down Increment up and down arrows.png buttons to select the desired period.
    • Define Period Add Note Icon.svg – If no period is defined, click to make the spreadsheet editable.
    • Delete Period GMS Delete Icon.svg – Click to delete the existing period.
    • Add Rows Row-add.svg – Click to bring up the Add Stresses dialog.
    • Delete Rows Row-delete.svg – Click to bring up a dialog with three options:
      • Delete from All Periods – Click to delete matching stresses from all periods.
      • Delete from Just This Period – Click to delete matching stresses from just this period.
    • Plot All Periods GMS MODFLOW 6 - Plot All Periods button.png – Click to bring up the XY Series Editor dialog. Requires that a cell be selected in the table.
    • Open Time Series Open Macro.svg – Click to bring up the
    • Filter on Selected Cells GMS MODFLOW 6 - Filter on Selected Cells button.png – Click to turn on filtering on the selected cells.
  • Table – Allows the manual input of different variables for the UZF Package.
    • IUZNO – An integer value that defines the UZF cell number associated with the specified PERIOD data on the line.
    • FINF – A value that defines the applied infiltration rate of the UZF cell.
    • PET – A value that defines the ET rate of the UZF cell and specified GWF cell.
    • EXDP – A value that defines the ET extinction depth of the UZF cell.
    • EXTWC – A value that defines the amount of water removed from the UZF cell through evapotranspiration.
    • HA – A value that defines the amount of potential air that enters the UZF cell.
    • HROOT – A value that defines the root potential of the UZF cell.
    • ROOTACT – A value that defines how much root activity exists in the UZF cell.
