TUFLOW Model Control dialog showing the Constituents tab.

SMS supports the TUFLOW Advection Dispersion (AD) module. This allows users to model 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 the user to enter 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

• Initial Condition – Specified Value or Polygon by Polygon value

• Minimum Dispersion Type

• Minimum Dispersion – Specified Value or Polygon by Polygon value

• Dispersion Coefficient

• Longitudinal
• Transverse

Boundary Conditions

For each boundary condition and constituent the user can 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, the user can 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.
