General Tab

 

 

The general data for this example is specified on the General tab. The Darcy velocity will be displayed but will be ignored when the Passive Sink option is selected.

 

 

Layers Tab

 

 

The layer data for this example consists of four layers: a primary liner, a unsaturated collection system, a saturated collection system, and a secondary liner. The data for these layers is specified on the Layers tab.

 

 

Boundaries Tab

 

 

The boundary conditions for this example are a constant concentration top boundary and a fixed outflow bottom boundary. These boundaries can be specified on the Boundaries tab.

 

 

Special Features

 

The biological decay and passive sink data for this model can be entered using the Special Features tab.

 

 

Passive Sink

 

 

The passive sink data is used to specify the Phase parameter and the horizontal and vertical Darcy velocities. In this example there are four depth intervals for the passive sink.

 

 

Radioactive/Biological Decay

 

 

The data for the biological decay of the DCM can be specified by selecting the Radioactive/Biological Decay option on the Special Features tab. In this example there are three decay intervals: one for the primary liner, one for the unsaturated and saturated collection system, and one for the secondary liner.
