A new instance of a source/sink of a particular type is created by selecting the '''Add''' button for the type. This creates a new source/sink and displays a default value or set of values for the source/sink in the edit fields on the right side of the dialog. If the simulation is steady state, normal edit fields are used to enter the values. If the simulation is transient, buttons appear which can be used to bring up the ''XY Series Editor | A new instance of a source/sink of a particular type is created by selecting the '''Add''' button for the type.

The '''Areal Sources/Sinks''' command is used to edit recharge and evapotranspiration parameters on a cell-by-cell basis. Before selecting the '''Areal Sources/Sinks''' command, a set of cells should be selected using the cell selection tools. Recharge and evapotranspiration parameters are applied to vertical columns rather than to individual cells. Therefore, to edit the value for a vertical column, any cell in the column can be selected. Once the '''Areal Sources/Sinks''' command is selected, the Areal Sources/Sinks dialog appears. The options in the dialog are as follows: | The '''Areal Sources/Sinks''' command is used to edit recharge and evapotranspiration parameters on a cell-by-cell basis.

===Packages=== | |||
If the Recharge package has not been activated (using the ''Packages'' dialog which is accessed through the ''Global Options\Basic Package'' dialog) the Recharge portion of the ''Areal Sources/Sinks'' dialog is dimmed. Likewise, if the Evapotranspiration package has not been activated, the Evapotranspiration portion of the dialog is dimmed. | If the Recharge package has not been activated (using the ''Packages'' dialog which is accessed through the ''Global Options\Basic Package'' dialog) the ''Recharge'' portion of the ''Areal Sources/Sinks'' dialog is dimmed.

===Editing Values=== | |||
The edit fields to the right of each option are used to enter the values of the parameters associated with each type. The fields are standard edit fields if the simulation is steady state and are graphic windows displaying a time series if the simulation is transient. Clicking on the window brings up the XY Series Editor. The XY Series Editor is a general purpose editor for entering curves or lists of pairs of data (e.g., rainfall rate vs. time). Once a curve is defined in the editor, it is displayed graphically in the window. | The edit fields to the right of each option are used to enter the values of the parameters associated with each type.

===Layers=== | |||
The Layer option in the Recharge portion of the dialog is only active (undimmed) if the Recharge at Specified Vertical Cells option is chosen in the ''Recharge Package'' dialog. Likewise, the Layer option in the Evapotranspiration portion of the dialog is only active if the ET at Specified Vertical Cells option is chosen in the ''Evapotranspiration Package'' dialog. | The ''Layer'' option in the ''Recharge'' portion of the dialog is only active (undimmed) if the ''Recharge at Specified Vertical Cells'' option is chosen in the ''Recharge Package'' dialog.

===Editing Multiple Cells=== | |||
After a set of source/sink parameters has been defined, it is often necessary to change one of the parameters of a subset of the cells (vertical columns). | After a set of source/sink parameters has been defined, it is often necessary to change one of the parameters of a subset of the cells (vertical columns). | ||
