GMS:MF6 RIV Package

The River (RIV) Package dialog

The River (RIV) 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.
  • Periods – Turn on to make the Periods section visible.
• 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.
  • Use auxiliary variable as multiplier (AUXMULTNAME) – Name of auxiliary variable to be used as multiplier of riverbed conductance.
  • Allow boundary names (BOUNDNAMES) – Turn on to allow boundary names to be included in the list of river cells.
  • Print input to listing file (PRINT_INPUT) – Turn on to write the list of river information to the listing file immediately after it is read.
  • Print flows to listing file (PRINT_FLOWS) – Turn on to write the list of river 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 river 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 River Package to be used with the Water Mover (MVR) Package.
• Periods section – Contains the following:
  • Period 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 GMS dialog and input values into the layer, row, column, and Q table found in the Periods section.
  • 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 – Options include:
  • LAY – Represents which layer within the module to which the chosen well will be assigned.
  • ROW – Represents which row within the module to which the chosen well will be assigned.
  • COL – Represents which column within the module to which the chosen well will be assigned.
  • STAGE – Variable that represents the head in the river.
  • COND – Variable that represents the riverbed hydraulic conductance.
  • RBOT – Variable that represents the elevation of the bottom of the riverbed.
