The Source/Sink Dialog

The Source/Sink Dialog is accessed by selecting a cell, right-clicking and choosing the option MODFLOW 6 GWF_Model- Cell Properties... in the right-click menu provided.

  • Packages: section – Provides a list of active packages within the module to choose and select depending on desired outcome.
  • 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 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 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 – Only available if a time series has previously been defined, and the time series is specifically called in the Head column. For example, if a time series named "ts_1" is defined, enter "ts_1" in the Head column of the appropriate row. Click to bring up the
    • Filter on Selected Cells Mf6filter.svg – Click to turn on filtering on the selected cells.

Table – Contains different information depending on the package chosen in the Packages: section. Options are as follows:

Package Table

COL – Used to specify certain columns.

HEAD – Represents the head at the boundary.

DRN LAY – Used to specify which layer is being applied.

ROW – Used to specify which row is being applied.

COL – Used to specify which column is being applied.

ELEV – Represents the elevation of the drain.

COND – Represents the hydraulic conductance between the aquifer and the drain.

GHB LAY – Used to specify certain layers of the module.

COND – Variable that represents the riverbed hydraulic conductance.

RBOT – Variable that represents the elevation of the bottom of the riverbed.

SFR RNO – A value that defines the reach number associated with the specified PERIOD data.

SFRSETTING – 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.

UZF 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.

WEL LAY – Represents which layer within the grid to which the chosen well will be assigned.

ROW – Represents which row within the grid to which the chosen well will be assigned.

COL – Represents which column within the grid to which the chosen well will be assigned.

Q – Represents the volumetric well rate at which the recharge (positive value) and discharge (negative value) of the well will be.
