= Introduction =
In this module, three culverts are added to represent flow through three separate road embankments. EPA SWMM is used as the solution scheme for the 1D culvert flow calculations, dynamically linked with the TUFLOW HPC 2D solution scheme. <br>

TUFLOW SWMM Tutorial Module 1 builds from the model created in <u>[[Tutorial_M02 |TUFLOW Tutorial Module 2]]</u> (in the TUFLOW Only tutorial dataset). The completed Module 2 model is provided in the '''''TUFLOW_SWMM_Module_01\TUFLOW''''' folder of the download dataset as the starting point for this tutorial. If you are not already familiar with TUFLOW, we recommend first completing Module 1 and 2 of the <u>[[Tutorial_Introduction | "TUFLOW Only" Tutorials]]</u> to establish an understanding of 2D modeling, before progressing to learning how to link 1D EPA SWMM to 2D TUFLOW. <br>

= Project Initialization =
Three steps are required for the project initialization:
<ol>
<li> Setting the  QGIS Project Coordinate Reference System (CRS).
<li> Configuring the QGIS TUFLOW Plugin.
<li> Establishing the new TUFLOW model GeoPackage file that will include new GIS inputs associated with this model update.
</ol>

== QGIS ==
QGIS Version 3.34 or newer, and QGIS TUFLOW Plugin 3.9.0.49 or newer are required to access the SWMM Processing Tools described in the following sections. For installation, see <u>[https://wiki.tuflow.com/index.php?title=TUFLOW_QGIS_Plugin#Installation_of_Plugin Installation of TUFLOW Plugin]</u>.<br>
Firstly, define the Coordinate Reference System (CRS), also called ‘Projection’, for the QGIS workspace:
<ol> 
<li>Open QGIS.
<li>Go to Project > Properties… 
<li>In the CRS tab, type ‘WGS 84 / UTM Zone 60S’.
<li>Select the matching projection in the 'Predefined Coordinate Reference Systems' section.
<li>Click ‘Apply’ and ‘OK’.
<li>Ensure that the projection is set correctly by viewing the bottom right hand corner of the workspace. It should read ‘EPSG:32760’.
</ol>
<br>
{{Video|name=Animation_TS1_Initialization_01a.mp4|width=1235}}<br>

==TUFLOW Plugin==
Next we need to configure the QGIS TUFLOW Plugin settings to link with the project folder where we will build our model:<br>
<ol>
<li>Open the 'Configure TUFLOW Project' tool by selecting Plugins > TUFLOW > Editing > Configure / Create TUFLOW Project. 
<li>In the previous section, the CRS (Coordinate Reference System) for the QGIS Workspace was defined. As such, the projection inputs are set automatically. 
<li>To set the location of the TUFLOW folder, click 'Browse...' and navigate to the '''TUFLOW_SWMM_Module_01'''. Click 'Select Folder'. 
<li>To set the location of the TUFLOW single precision executable file, click 'Browse...' and navigate to the '''exe\2023-03-AD''' folder. Select '''TUFLOW_iSP_w64.exe''' and click 'Open'.
<li>Select 'GPKG' as the GIS Format. 
<li>Select 'TUFLOW Classic / HPC' as the TUFLOW Engine.
<li>Tick on 'Save Default Settings Globally'.
<li>Click 'OK'.<br>
<br>
{{Video|name=Animation_TS1_Initialization_02c.mp4|width=1235}}
<br>
</ol>

==TUFLOW Model==
===Load and Style TUFLOW Model Files===
Load and Style the GIS layers from the TUFLOW model:
<ol>
<li>Click on the ‘Load TUFLOW Layers from TCF’ symbol from the TUFLOW Plugin toolbar.
<br>
[[File: Tuflow_plugin_load_tcf_layers.png]]<br>
<br>
<li>In File Explorer, navigate to the '''TUFLOW_SWMM_Module_01\TUFLOW\runs''' folder and select '''M02_5m_001.tcf'''.
<li>In the Load Layers window, select:
* Ordering Options: Alphabetical
* Grouping Options: Group by control file
* Raster Load Options: Load Normally 
<li>Click ‘Open’ and ‘OK’.
</ol>
<br>

Style the TUFLOW layers however you desire. Common steps to do this are:
<ol>
<li>Click on the ‘Apply TUFLOW Styles to Open Layers’ symbol from the TUFLOW Plugin toolbar.
<br>
[[File:tuflow_plugin_styles_open_layers.png]]<br>
<br>
<li>Change the symbology of the DEM:
*Right click on the '''DEM''' file in the QGIS Layers Panel and select 'Properties'.
*From the Symbology tab, under 'Band Rendering' select the following options:
:*Render type: Singleband pseudocolor
:*Color ramp: Spectral
:*Color ramp: Invert Color Ramp
:*Mode: Equal Interval
*From the Transparency tab, set the Global Opacity to 75%.
*Click 'Apply' and 'OK'.
<br>
{{Video|name=Animation_TS1_Initialization_03c.mp4|width=1235}}<br>
<li>Create a hillshade of the DEM:
*Right click on the '''DEM''' file in the QGIS Layers Panel and select 'Duplicate Layer'.
*Right click on the '''DEM_copy''' and select 'Rename Layer'. Rename the layer to '''DEM_Hillshade'''.
*Right click on the '''DEM_Hillshade''' and select 'Properties'.
*From the Symbology tab, under 'Band Rendering' select the following options:
:*Render type: Hillshade
:*Z Factor: 3
*Click 'Apply' and 'OK'.
<br>
{{Video|name=Animation_TS1_Initialization_04a.mp4|width=1235}}<br>
</ol>

=== Increment Model GeoPackage File === 
We will now save a copy of '''M02_001.gpkg''' with a new name, '''TS01_001.gpkg'''. This project initialization step is recommended so prior model versions from a project are not broken as a result of changes being made to GIS inputs.

<ol>
<li>In the QGIS Layers Panel, select (left click) '''2d_bc_M01_001_L'''.
<li>Click on the 'Increment Selected Layer' symbol from the TUFLOW Plugin toolbar. This opens the dialog shown below. 
<br>
[[File:tuflow_plugin_increment_layer.png]]<br>
<br>
:*Source Layer: Automatically set to the selected layer, '''2d_bc_M01_001_L'''.
:*Output Database: Click 'Browse...'. This will automatically open to the '''TUFLOW\model\gis''' folder. Set the new output database name to '''TS01_001.gpkg''' and click 'Save'.
:*Output Layer Name: Automatically set to the selected layer, '''2d_bc_M01_001_L'''.
:*Delete the pre-filled 'Incremented Layer' entry in the table. We do not wish to modify the version number associated with the 2d_bc file. This current exercise will not change the version number of any of the GIS layer inputs, it is simply establishing a copy of the existing GeoPackage where future edits will be saved to.
:*Select 'Remove Source Layer from Workspace'.
:*Select 'Increment Layer and Preserve Database'.
<li>Click 'OK'.<br>
<br>
{{Video|name=Animation_TS1_Initialization_05a.mp4|width=1235}}
<br>
</ol>

===Save QGIS Project Workspace===
<ol>
<li>Go to Project > Save As.
<li>Navigate to the '''TUFLOW_SWMM_Module_01''' folder and type '''SWMM_M01''' as the filename with the extension .qgz.
</ol>
<br>

= SWMM Inputs and 1D/2D Linking=
==Create SWMM GeoPackage Spatial Database== 
Create a new folder in the '''TUFLOW_SWMM_Module_01\TUFLOW\model''' folder called '''swmm'''. This is the location where all SWMM inputs will be saved.<br>
<br>
In QGIS, create the SWMM GeoPackage Database:
<ol> 
<li>Go to Processing > Toolbox from the top dropdown menu options to open the Processing Toolbox panel.
<li>Go to TUFLOW > SWMM in the processing tool list and select '<u>[[QGIS_SWMM_GeoPackage_Create |GeoPackage - Create]]</u>'. This opens the dialog shown below.
:*To set the ‘CRS for GeoPackage’: Click the drop down menu and select ‘Project CRS: EPSG:32760 - WGS 84 / UTM zone 60S’.
:*To set the ‘Initial SWMM Sections’: Click …, and tick on: 
:**'''Project--Title''', '''Project--Options''', '''Project --Report.'''
:**'''Nodes--Junctions''', '''Nodes--Outfalls.''' 
:**'''Links--Conduits, Links--Streets'''. 
:*To define the ‘GPKG filename to create’: Click …, select ‘Save to File’. Navigate to the '''TUFLOW\model\swmm''' folder and save the GeoPackage database as '''sw01_001.gpkg'''.


<li>Click ‘Run’. 
<li>Once the tool has finished, click ‘Close’.
<li>In File Explorer, navigate to the '''TUFLOW\model\swmm''' folder and drag and drop '''sw01_001.gpkg''' into QGIS. 
<li>When prompted by QGIS, under 'Options', tick on 'Add layers to group', then select 'Add Layers' to open all vectors within '''sw01_001.gpkg'''. By default, all items in the available list should have been selected. 
<li>In the QGIS Layers panel, move '''sw01_001.gpkg''' to the top of the list. This will ensure the data within this database file is displayed above all other layers in the project. 
</ol>
<br>
{{Video|name=Animation_TS1_SWMM_Inputs_01f.mp4|width=1235}}
<br>
<br>

== GIS Data Entry ==

A GeoPackage database called '''SWMM_Culverts.gpkg''' is provided in the '''TUFLOW_SWMM_Module_01\Tutorial_Data''' folder. It contains three layers: 
:*'''Conduits:''' defines the culvert location, type and geometry.
:*'''Junctions:''' defines the upstream culvert inverts.
:*'''Outfalls:''' defines the downstream culvert inverts.
<br>
To populate the GeoPackage database created in the previous section:
<ol>
<li>In Windows Explorer, navigate to the '''TUFLOW_SWMM_Module_01\Tutorial_Data''' folder. Drag and drop the '''SWMM_Culverts.gpkg''' into QGIS. 
<li>When prompted by QGIS, under 'Options', tick on 'Add layers to group'. By default, all items in the GeoPackage database will be selected. Click 'Add Layers'.
<li>In the QGIS Layers panel, right click on the '''SWMM_Culverts''' >> '''Conduits''' layer and select 'Zoom to Layer'.
<li>Use the 'Select Features' tool to highlight all items included in '''Conduits'''.
<li>Select 'Edit' from the top QGIS tab and 'Copy Features' from the drop down menu. 
<li>In the QGIS Layers Panel, select (left click) the '''sw01_001.gpkg''' >> '''Links--Conduits''' layer. 
<li>Make the '''Links--Conduits''' layer editable by clicking the 'Toggle Editing' symbol [[File:toggle_editing_icon.png|27x27px]].
<li>Select 'Edit' from the top QGIS tab and click 'Paste Features' from the drop down menu.
<li>Toggle the editing off to save the edits.<br>
<br>
{{Video|name=Animation_TS1_SWMM_Inputs_02e.mp4|width=1235}}
<br>
<li>Similarly, copy the objects from '''Junctions''' into '''Nodes--Junctions'''. Junctions are considered inlets, and should be defined at the upstream end of culverts.
<li>Also copy the objects from '''Outfalls''' into '''Nodes--Outfalls'''. Outfalls are treated as outlets, and are required at the downstream end of culverts.
<li> Toggle off editing and save the edits.
<li>Remove '''SWMM_Culverts.gpkg'''.
<br><br>
{{Video|name=Animation_TS1_SWMM_Inputs_03e.mp4|width=1235}}
<br>
<li>Inspect the attribute information within the respective layers to familiarize yourself with the data.
<br><br>
{{Video|name=Animation_TS1_SWMM_Inputs_04e.mp4|width=1235}}
</ol>
<br>

== GIS Data Updates ==
The provided GIS data requires numerous updates before proceeding to a model simulation. We have intentionally built these updates into this tutorial to demonstrate some of the available TUFLOW SWMM model build processing tools. The following updates are being made to objects and layers within '''sw01_001.gpkg'''.
===Update Conduit Details===
==== Node Details ====
Step 1 involves updating the ''From Node'' and ''To Node'' attribute information in '''Links--Conduits'''. This information is necessary to build the 1D SWMM network. It defines the Link/Node connections. The information we will be adding to '''Links--Conduits''' is extracted from '''Nodes--Junctions''' and '''Nodes--Outfalls''' automatically using the '<u>[[QGIS_SWMM_Conduits_Assign_Node_Fields |Conduits - Assign node fields]]</u>' tool from the Processing Toolbox.
<ol>
<li>In the QGIS Layers panel, select (left click) '''Links--Conduits''' and toggle on editing.
<li>In the Processing Toolbox, select the 'Edit Features In-Place' tool [[File:edit_features_in_place_icon.png]]. This allows the editing of an existing layer, instead of the creation of a new layer.
<li>Go to TUFLOW > SWMM in the processing tool list and select '<u>[[QGIS_SWMM_Conduits_Assign_Node_Fields |Conduits - Assign node fields]]</u>'. 
<li>Tick on the SWMM Node Layers: '''Nodes--Junctions''' and '''Nodes--Outfalls'''.
<li>Select 'Modify All Features'.
<li>Once the tool has finished, click 'Close'.
<li>Turn off editing to save the edits.
<li>View the attributes associated within '''Links--Conduits''' to verify the data processing has been completed correctly. The 'From Node' and 'To Node' attribute information is now configured correctly. For a broader understanding of the other attributes associated with the '''Links---Conduits''' Layer, refer to <u>[https://docs.tuflow.com/classic-hpc/release/2023-03-AD/SWMM-Input-Detailed-1.html#tab:tab-SWMM-Input-Conduits TUFLOW 2023-03-AD Release Notes (Table A.19)]</u> and the <u>[https://downloads.tuflow.com/SWMM/SWMM5_Reference_Manual_Volume2_Hydaulics_P100S9AS.pdf SWMM Reference Manual - Volume 2 (Hydraulics)]</u>. <br>
<br>
'''Tip1:''' If you wish to only update a selection of objects, instead of selecting the entire '''Link--Conduits''' dataset, select the target objects first using the Feature by Area tool. The '<u>[[QGIS_SWMM_Conduits_Assign_Node_Fields |Conduits - Assign node fields]]</u>' tool will provide an option to 'Modify Selected Features', instead of 'Modify All Features.'<br>
'''Tip2:''' Unique Node ID's are required for the SWMM network to function error free. If you are following this workflow for a project model build, please ensure the '''Nodes--Junctions''' and '''Nodes--Outfalls''' object ID information is unique. If duplicate ID values are assigned to multiple objects, consider using the '<u>[[QGIS_SWMM_Integrity_Make_Node_Names_Unique |Integrity - Make node names unique ]]</u>' TUFLOW SWMM processing tool to ensure all ID values are unique before using '<u>[[QGIS_SWMM_Conduits_Assign_Node_Fields |Conduits - Assign node fields]]</u>'.
<br><br>
{{Video|name=Animation_TS1_SWMM_Inputs_05e.mp4|width=1235}}
<br>


</ol>

====Update Losses====

Step 2, update the loss attributes in the '''Links--Conduits''' layer. These values will be entered manually in this example using default values. Variation to the default values can be used in project models to reflect site specific information if desired. 
<ol>
<li>In the QGIS Layers panel, select (left click) '''Links--Conduits''' and toggle on editing.
<li>Right click '''Links--Conduits''' and select 'Open Attribute Table'.
<li>Update the following fields:
:*losses_Kentry: 0.5
:*losses_Kexit: 1.0
:*losses_Kavg: 0.0
The video below demonstrates how to do this one entry at a time, or via the bulk attribute update options in QGIS.
<li>Turn off editing to save the edits.
<br><br>
{{Video|name=Animation_TS1_SWMM_Inputs_06e.mp4|width=1235}}
</ol>
<br>
An urban pipe network is added to the model in <u>[[TUFLOW_SWMM_Tutorial_M02 | TUFLOW SWMM Module 2]]</u>. In that situation, different loss attributes are required for the road culverts and underground stormwater pipe network links. To simplify the loss attribute update step in that situation, we will be using the '<u>[[QGIS_SWMM_Conduits_Assign_Node_Fields |Conduits - Assign node fields]]</u>' processing tool. However, it is not necessary for this Module 1 tutorial, because all the 1D SWMM inputs are embankment culverts all using the same loss parameters.
<br>
<br>

=== Create 1D/2D Connections===
The following instructions introduce a new tool that automates the creation of 1D/2D connections. Due to the limitations of SWMM boundary conditions, HX lines are required for the upstream end of the culvert (rather than SX), and SX connections are used at the downstream end of the culvert.<br>
<ol>
<li>In the QGIS Layers panel, select (left click) '''Links--Conduits'''.
<li>In the Processing Toolbox, go to TUFLOW > SWMM and select '<u>[[QGIS_SWMM_BC_Create_Channel_Endpoint_1D/2D_Connections |BC - Create channel endpoint 1D/2D connections]]</u>'. This opens the dialog shown below.  
:*Input Conduits Layer: '''Links--Conduits'''
:*Create connections at: 'Both ends'. 
:*Offset Distance: 2
:*Length of BC lines: 10
:*Tick on 'Set 2D cell elevation to 1D culvert invert at 1D/2D connection cells if needed'.
:*Output Layer:
<ol>
::<li>Click the ... and select 'Save to GeoPackage'.
::<li>Navigate to the '''TUFLOW\model\gis''' folder and select '''TS01_001.gpkg'''. Click Save. 
::<li>A dialog will open. In the Layer name field, write '''2d_bc_SWMM_Culvert_Connections_001_L'''.
::<li>Click 'OK'.
</ol>
<li>Click 'Run'.
<li>Once the tool is finished, click 'Close'.
<li>The '''2d_bc_SWMM_Culvert_Connections_001_L''' appears in the Layers panel. Select 'Apply TUFLOW Styles to Current Layer'.
<br><br>
{{Video|name=Animation_TS1_SWMM_Inputs_07e.mp4|width=1235}}
</ol>
<br>
'''Note:''' The positions of the HX and SX connections may not be in the optimum location or extent using the generalized automated tool. As such, it is recommended to check the output from this processing step. In this module, the 1D/2D connections associated with '''2d_bc_SWMM_Culvert_Connections_001_L''' are checked in <u>[[TUFLOW SWMM Tutorial M01 Check QGIS|TUFLOW SWMM Tutorial 01 Check Files]]</u>.
<br>
<br>

===Update Junction Details===

<ol>
<li>In the QGIS Layers panel, select (left click) '''Nodes--Junctions''' and toggle on editing.
<li>In the Processing Toolbox, select the 'Edit Features In-Place' tool. This allows the editing of an existing layer, instead of the creation of a new layer.
<li>Go to TUFLOW > SWMM in the processing tool list and select '<u>[[QGIS_SWMM_Junctions_Set_Attributes |Junctions - Set attributes ]]</u>' processing tool. This opens the dialog shown below.
:*Input BC Connection Layers: '''2d_bc_SWMM_Culvert_Connections_001_L'''
:*Nodes connected to 2D without Inlets (Ysur): 0
:*Nodes connected to 2D without Inlets (Apond): 50

<li>Select 'Modify All Features'.
<li>Once the tool has finished, click 'Close'.
<li>Turn off editing to save the edits.
<li>View the attributes associated within '''Nodes--Junctions''' to verify the data processing has been completed correctly.
For a summary of the attributes associated with the '''Nodes--Junctions''' layer, refer to <u>[https://docs.tuflow.com/classic-hpc/release/2023-03-AD/SWMM-Input-Detailed-1.html#tab:tab-SWMM-Input-Junctions TUFLOW 2023-03-AD Release Notes (Table A.30)]</u> and the <u>[https://downloads.tuflow.com/SWMM/SWMM5_Reference_Manual_Volume2_Hydaulics_P100S9AS.pdf SWMM Reference Manual - Volume 2 (Hydraulics)]</u>.
<br><br>
{{Video|name=Animation_TS1_SWMM_Inputs_08e.mp4|width=1235}}
<br>
</ol>

==SWMM Options==
<ol>
<li>In the QGIS Layers panel, select (left click) '''Project--Options''' and toggle on editing. 
<li>Right click '''Project--Options''' and select 'Open Attribute Table'.
<li>Update the following options: 
*'''START_DATE''': 2020-01-01 (Date Format: YYYY-MM-DD)
*'''REPORT_STEP''': 00:01:00
<li>Turn off editing to save the edits.  
</ol>

{{Video|name=Animation_TS1_SWMM_Inputs_09e.mp4|width=1235}}
<br>Save the QGIS Project Workspace:

# Go to Project > Save. This will update '''SWMM_M01.qgz''', which you created previously in the folder '''TUFLOW_SWMM_Module_01'''.<br>

== Export SWMM INP File ==
SWMM is not able to read the '''sw01_001.gpkg''' database directly, therefore, we need to convert the GeoPackage file to a SWMM INP file format.

<ol>
<li>In the Processing Toolbox, go to TUFLOW > SWMM and select '<u>[[QGIS_SWMM_GeoPackage_Write_to_SWMM_inp |GeoPackage - Write to SWMM inp]]</u>'. 
:*GeoPackage Input File: Navigate to the '''TUFLOW\model\swmm''' folder and select '''sw01_001.gpkg'''.<br>

<li>By default, this tool will save the SWMM inp file in the same folder location and with the same name as the GeoPackage input file. In this case, it will save '''sw01_001.inp''' to the '''TUFLOW\model\swmm''' folder.
<li>Click 'Run'.
<li>Once the tool is finished, click 'Close'.
<br><br>
{{Video|name=Animation_TS1_SWMM_Inputs_10d.mp4|width=1235}}
</ol><br>

= Simulation Control Files =
The following steps will require use of a text editor. The tutorial demonstration uses Notepad++. For its configuration information refer to <u>[[NotepadPlusPlus_Tips | Notepad++ Tips]]</u>. <br>

To differentiate the TUFLOW SWMM tutorials from the TUFLOW/ESTRY tutorials, TS will be used as the new file prefix in this series of tutorials. To avoid the potential risk of overwriting existing control files accidentally, we will start by saving new control files where we will be making subsequent syntax updates during the following steps. <br>

Set up the simulation control files:
<ol>
<li>Open '''M02_5m_001.tcf''' from the TUFLOW/runs folder in a Text Editor (Notepad++ is recommended). Save the file as '''TS01_5m_001.tcf''' in the '''TUFLOW_SWMM_Module_01\TUFLOW\runs''' folder.
<li>Open '''M01_001.tbc''' using the "Open File" function in Notepad++. Save the file as '''TS01_001.tbc''' in the '''TUFLOW_SWMM_Module_01\TUFLOW\model''' folder.
<li>Create a new blank text file called '''TS01_001.tscf''' and save it in the '''TUFLOW_SWMM_Module_01\TUFLOW\model''' folder.
