Section 2 TUFLOW Commands

This section is a reference for the commands available in a combined TUFLOW and SWMM model.

2.1 TUFLOW Control File Commands (TCF)

SWMM Control File == <<swmm_control_filename.scf>

This command identifies the SWMM control file which contains the relevant commands needed to manage the SWMM simulation.

2.2 SWMM Control File Commands (SCF)

This section describes SWMM related commands that are used in the SWMM Control File (SCF). Commands for scenario and event management are not included but are supported, such as “If Scenario,” “If Event,” “Else,” or “End If.” Such commands are described in the TUFLOW manual.

Read SWMM == <swmm_inp_filename>

This command adds the SWMM input file to the SWMM simulation. Multiple SWMM input files can be specified which will be combined into a single 1D SWMM simulation.

Read GIS SWMM Inlet Usage == <swmm_inlet_usage_filename>

This command reads a SWMM inlet usage filename to identify locations and attributes of inlets (pits) that connect the 2D TUFLOW and 1D SWMM models.

SWMM Iterations == [1]

Controls the number of iterations that are run for each 2D timestep. Increasing the number decreases the timestep used by SWMM potentially improving model stability but increasing run time.
