The [[GMS:MT3DMS_Source/Sink_Mixing_Package|''Source/Sink Mixing Package'']] dialog can be used to edit both point and areal sources/sinks using a spreadsheet. In many cases, it is more convenient to view and edit source sink concentrations on a cell-by-cell basis. Two commands are provided to facilitate this type of editing: the '''Point Sources/Sinks''' command and the '''Areal Sources/Sinks''' command. | |||

The '''Point Sources/Sinks''' command is used to assign and edit the concentrations at point sources and sinks.

A point source/sink concentration for each species is assigned to the selected cells by selecting the toggle corresponding to the type of source/sink. The concentration at the cells can be specified as either constant or transient. If a constant value is specified, this number will be used for all stress periods. If the Variable option is used, clicking on the window brings up the XY Series Editor. The [[XY Series Editor|XY Series Editor]] is used to assign a concentration value for each stress period. | A point source/sink concentration for each species is assigned to the selected cells by selecting the toggle corresponding to the type of source/sink.

The '''Areal Sources/Sinks''' command is used to edit the concentrations assigned to recharge and evapotranspiration fluxes. Before selecting the '''Areal Sources/Sinks''' command, a set of cells should be selected using the cell selection tools. The concentration fluxes due to [[GMS:RCH Package|recharge]] and [[GMS:EVT Package|evapotranspiration]] 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 MT3DMS Areal Sources/Sinks dialog appears. | The '''Areal Sources/Sinks''' command is used to edit the concentrations assigned to recharge and evapotranspiration fluxes.

The areal source/sink concentration values at the selected cells can be edited by highlighting a species and either selecting a constant value for all stress periods, or by defining a set of values. | The areal source/sink concentration values at the selected cells can be edited by highlighting a species and either selecting a constant value for all stress periods, or by defining a set of values. | ||
