Introduction

In this module, three culverts are added to represent flow through embankments that block the main flow paths. EPA SWMM is used as the solution scheme for the 1D culvert flow calculations, dynamically linked with the TUFLOW HPC 2D solution scheme.

The GIS layers are:

  • TSCF (TUFLOW SWMM Control File) layers:
    1. 1d_SWMM_Inlet: A layer used to define culvert inlet nodes.
  • TBC layers:
    1. 2d_bc: A layer defining the locations of 1D/2D links.

Module 3 builds from the model created in TUFLOW Module 2. The completed Module 2 model is provided in the TUFLOW_SWMM_Module_01\TUFLOW folder.

GIS Inputs

Create, import and view input data:


Simulation Control Files

TUFLOW Boundary Control File (TBC)

To diferentiate the TUFLOW SWMM tutorials from the TUFLOW/ESTRY tutorials, TS will be used as the new file prefix in this series of tutorials.

  1. Save a copy of the M01_001.tbc as TS01_001.tbc in the TUFLOW_SWMM_Module_01\TUFLOW\model folder.
  2. Open TS01_001.tbc in a text editor and add the additional lines:
    QGIS - GPKG
    Read GIS BC == 2d_bc_SWMM_Connections_001_L ! Links the 1D culverts to the 2D domain
  3. Save the TBC.

TUFLOW SWMM Control File (TSCF)

A new control file, the TUFLOW SWMM Control File (TSCF), is introduced. SWMM is a 1D hydraulic solver. All 1D SWMM files and commands are referenced in the TUFLOW SWMM Control File.

  1. Create a new text file TS01_001.tscf and save it in the TUFLOW_SWMM_Module_01\TUFLOW\model' folder.
  2. Add the following command lines:
    QGIS - GPKG
    Read SWMM == ..\swmm\TS01_001.inp ! 1D SWMM input file
    Read GIS SWMM Inlet Usage == 1d_SWMM_Inlet ! Something??
  3. Save the TSCF.

TUFLOW Control File (TCF)

  1. Save a copy of the M02_5m_001.tcf as M03_5m_001.tcf in the Module_03\TUFLOW\runs folder.
  2. Open the M03_5m_001.tcf in a text editor and add the following line in the 'Model Inputs' section:
    ESTRY Control File == ..\model\M03_001.ecf ! Reference the ESTRY (1D) Control File
  3. Make the following reference updates:
    QGIS - SHP
    BC Control File == ..\model\M03_001.tbc ! Reference the TUFLOW Boundary Conditions Control File
  4. QGIS - GPKG
    Spatial Database == ..\model\gis\M03_001.gpkg ! Specify the location of the GeoPackage Spatial Database
    BC Control File == ..\model\M03_001.tbc ! Reference the TUFLOW Boundary Conditions Control File
  5. Save the TCF.


Running the Simulation

  1. Save a copy of _run_M02_HPC.bat as _run_M03_HPC.bat in the Module_03\TUFLOW\runs folder.
  2. Update the batch file to reference the M03_5m_001.tcf :
    set exe="..\..\..\exe\2023-03-AA\TUFLOW_iSP_w64.exe"
    set run=start "TUFLOW" /wait %exe% -b
    %run% M03_5m_001.tcf
  3. Double click the batch file in file explorer to run the simulation.


Troubleshooting

See tips on common mistakes and troubleshooting steps if the model doesn't run:


Check Files

While the model is running, review the added features are specified correctly:


Results

When the model is finished, review the results:


Conclusion

  • Culverts were added to the model. Three different SX boundary applications were used to transfer flow through road embankments.
  • Check files were used to review the application of the boundary links.
  • Results through the 1D network structures were assessed to validate the 1D stability.
