TUFLOW Model Control dialog showing the Constituents tab.

SMS supports the TUFLOW Advection Dispersion (AD) module. This allows modeling constituents using TUFLOW.

The TUFLOW AD module can be added to a paid edition of SMS.

Creating the Constituents

The constituent data is entered in the Model Control of the TUFLOW simulation. The Constituents tab allows entering in the following parameters for each constituent:

• Name – Enter the name for the constituent here.
• Decay rate (units of day^-1)
• Settling rate (units of m/day)
• Initial Condition Type – Specified for each constituent as either a constant value or spatially variant. Select either "Constant" to enter a constant value or "Coverage" to select a spatial attributes (Miscellaneous) coverage.

• Initial Condition – Specified value for constant value or Select option to open a Select Coverage dialog to specify a spacial attributes coverage.

• Minimum Dispersion Type

• Minimum Dispersion – Specified Value or Polygon by Polygon value

• Dispersion Coefficient

• Longitudinal
• Transverse

Boundary Conditions

For each boundary condition and constituent, provide a curve representing concentration at the boundary. This can be done by selecting the Advection Dispersion BC... button in the Properties dialog for the arc or polygon. This brings up the Advection Dispersion dialog. In the dialog, select a constituent from the list provide. The list is generated from constituents in the Constituents tab of the TUFLOW 2D Model Control dialog.

Clicking the curve button to the right will bring up an XY Series Editor dialog where the curve information can be entered.
