The Constant-Head (CHD) Package dialog

The Constant-Head (CHD) Package dialog is accessed by double-clicking on the CHD 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.

  • Options section – Contains the following:
    • 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.
    • Use auxiliary variable as multiplier (AUXMULTNAME) – Name of auxiliary variable to be used as multiplier of CHD head value.
    • Allow boundary names (BOUNDNAMES) – Turn on to allow boundary names to be included in the list of constant-head cells.
    • Print input to listing file (PRINT_INPUT) – Turn on to write the list of constant-head information to the listing file immediately after it is read.
    • Print flows to listing file (PRINT_FLOWS) – Turn on to write the list of constant-head flow rates to the listing file for every stress period time step in which "BUDGET PRINT" is specified in Output Control.
    • Save flows to budget file (SAVE_FLOWS) – Turn on to write constant-head flow terms to the file specified with "BUDGET FILEOUT" in Output Control.
    • Use with Water Mover (MVR) package (MOVER) – Turn on to allows this instance of the Constant-Head Package to be used with the Water Mover (MVR) Package.
  • Periods section – Contains the following:
    • Period 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 from Just This Period – Click to delete matching stresses from just this period.
    • Plot All Periods Mf6time-series.svg – 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 Mf6filter.svg – Click to turn on filtering on the selected cells.
      • Table – Contains the following:
        • LAY – Used to specify which layer you wish to apply.
        • ROW – Used to specify which row you wish to apply.
        • COL – Used to specify which column you wish to apply.
        • HEAD – Represents the head at the boundary.
