GMS:MF6 MAW Package

The Multi-Aquifer Well (MAW) Package dialog

The Multi-Aquifer Well (MAW) 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.
• Options section – Temporal options and settings:
  • BOUNDNAMES – If turned on, indicates that the list of multi-aquifer well cells will be provided with the associative boundary names.
  • PRINT_INPUT – If turned on, indicates that the list of multi-aquifer well information will be written to the listing file after it is read.
  • PRINT_HEAD – If turned on, indicates that well heads will be printed to the listing file for each stress period that "HEAD PRINT" is specified.
  • PRINT_FLOWS – If turned on, indicates that a list of multi-aquifer well flow rates will be printed to the listing file.
  • SAVE_FLOWS – If turned on, indicates that the multi-aquifer well flow terms will be written to a specified file.
  • HEAD_FILEOUT – The name of the output file to write stage information.
  • BUDGET_FILEOUT – Allows the specification of a file to which desired flow terms will be written.
  • NO_WELL_STORAGE – If turned on, indicates that well storage will not be included in the continuity equation. It is used to control discharge rate oscillations.
  • FLOWING_WELLS – If turned on, indicates that the flowing wells option is activated.
  • SHUTDOWN_THETA – Defines the weight that is applied to the discharge rate for wells that have water limitations.
  • SHUTDOWN_KAPPA – Defines the weight that is applied to the discharge rate for wells that have water limitations. It is used to control discharge rate oscillations.
  • MOVER – When turned on, indicates that the Unsaturated Zone Flow (SFR) Package, in this instance can be used in collaboration with the Water Mover (MVR) Package.
• Data section – Contains the following:
  • Periods drop-down – Use the Increment Up and Down buttons to select the desired period.
  • Define Period – If no period is defined, click to make the spreadsheet editable.
  • Delete Period – Click to delete the existing period.
  • Add Rows – Click to bring up the Add Stresses dialog.
  • Delete Rows – 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 – Click to bring up the XY Series Editor dialog. Requires that a cell be selected in the table.
  • Open Time Series – Click to bring up the
  • Filter on Selected Cells – Click to turn on filtering on the selected cells.
    • Table – Allows the manual input of different variables for the MAW Package.
      • WELLNO – A value that defines the reach number associated with the specified PERIOD data.
      • MAWSETTING – Information that is linked to keywords and values.
      • VALUE1 – Value to be entered in relation to the specific project.
      • VALUE2 – Value to be entered in relation to the specific project.
      • VALUE3 – Value to be entered in relation to the specific project.
