= Introduction =
This tutorial, Module 2 of the TUFLOW SWMM tutorial dataset will demonstrate how to model underground stormwater pipe networks using SWMM, linked to the TUFLOW HPC 2D solution scheme. Boundary condition inflows to the model are defined using TUFLOW's 2D direct rainfall (rain on grid) approach. TUFLOW SWMM Tutorial Module 2 builds from the model created in <u>[[TUFLOW_SWMM_Tutorial_M01|TUFLOW SWMM Tutorial Module 1]]</u>. The completed TUFLOW SWMM Module 1 model is provided in the '''''TUFLOW_SWMM_Module_02\TUFLOW''''' folder of the download dataset as the starting point for this tutorial. If you are not already familiar with TUFLOW SWMM linking, we recommend completing TUFLOW SWMM Module 1 prior to starting this tutorial. <br>
In this module, stormwater inundation and underground pipe flows associated with an urban development are modelled. EPA SWMM is used as the solution scheme for the 1D pipe and culvert flow calculations, dynamically linked with the TUFLOW HPC 2D solution scheme. <br>

<li>Change the symbology of the DEM:
=== Increment TUFLOW GeoPackage File ===
*Right click on the '''DEM''' file in the Layers panel and select 'Properties'.
We will now save a copy of '''TS01_001.gpkg''' with a new name, '''TS02_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.
*From the Symbology tab, under 'Band Rendering' select the following options:
 
:*Render type: Singleband pseudocolor
<ol>
:*Color ramp: Spectral
<li>In the QGIS Layers Panel, select (left click) '''2d_bc_M01_001_L'''.
:*Color ramp: Invert Color Ramp
<li>Click on the 'Increment Selected Layer' symbol from the TUFLOW Plugin toolbar. This opens the dialog shown below.
:*Mode: Equal Interval
*From the Transparency tab, set the Global Opacity to 75%.
*Click 'Apply' and 'OK'.
<br>
[[File:tuflow_plugin_increment_layer.png]]<br>
{{Video|name=Animation_TS1_Initialization_02a.mp4|width=1235}}<br>
<br>
<li>Create a hillshade of the DEM:
:*Source Layer: Automatically set to the selected layer, '''2d_bc_M01_001_L'''.
*Right click on the '''DEM''' file in the Layers panel and select 'Duplicate Layer'.
:*Output Database: Click 'Browse...'. This will automatically open to the '''TUFLOW\model\gis''' folder. Set the new output database name to '''TS02_001.gpkg''' and click 'Save'.
*Right click on the '''DEM_copy''' and select 'Rename Layer'. Rename the layer to '''DEM_Hillshade'''.
:*Output Layer Name: This will automatically increment to '''2d_bc_M01_00''2''_L'''. Change the name back to '''2d_bc_M01_00''1''_L'''.
*Right click on the '''DEM_Hillshade''' file and select 'Properties'.
:*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.
*From the Symbology tab, under 'Band Rendering' select the following options:
:*Select 'Remove Source Layer from Workspace'.
:*Render type: Hillshade
:*Select 'Increment Layer and Preserve Database'.
:*Z Factor: 3
<li>Click 'OK'.
*From the Transparency tab, set the Global Opacity to 35%.
<li>The GeoPackage database, '''TS02_001.gpkg''' will now be in the '''TUFLOW_SWMM_Module_02\TUFLOW\model\gis''' folder.

==Create SWMM GeoPackage Spatial Database==
InWe QGIS,will create a new SWMM GeoPackage database for the newour pipe network features we'll be adding to thefeature modelentries:
<ol>
<li>Go to Processing > Toolbox from the top dropdropdown 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 the …, and tick on: '''Title''',(if '''Nodes--Junctions''',not '''Nodes--Outfalls''',already '''Links--Conduits''', '''Streets''', '''Inlets''' andticked): '''Report'''.
::*'''Nodes--Junctions''', '''Nodes--Outfalls.'''
:*To define the ‘GPKG filename to create’: Click the …, select ‘Save to File’. Navigate to the '''TUFLOW\model\swmm''' folder and save the GeoPackage Database as '''TS02_001.gpkg'''.
::*'''Links--Conduits, Links--Streets.'''
 
::*'''Inlets--Inlets.'''
 
:*To define the ‘GPKG filename to create’: Click the …, select ‘Save to File’. Navigate to the '''TUFLOW\model\swmm''' folder and save the GeoPackage Database as '''sw02_001.gpkg'''.
<li>Click ‘Run’.
::'''Note:''' In Module 1 we also included '''Nodes--Storage''', '''Project--Title''', '''Project--Options''', and '''Project--Report''' in the GeoPackage file. '''Project--Options''' is not required this time as this tutorial model will use two SWMM INP files. The file created during Module 1 (for the road culverts) and the INP is to be created from this GeoPackage (for the underground pipe network inputs). When TUFLOW processes SWMM inputs, it combines the multiple INP files into one before simulation. As such, the details from the Module 1 '''Project--Options''' input will be used in this tutorial. If '''Project--Options''' are included in multiple Geopackage/INP files, the entry that is referenced lowest in the TUFLOW SWMM Control file (TSCF) will be used. '''Nodes--Storage''' will not be used in this tutorial, as these are only needed to represent detention, or for nodes connected using HX boundaries.
<li>Click 'Run'.
<li>Once the tool has finished, click ‘Close’.
<li>In Windows File Explorer, navigate to the '''TUFLOW\model\swmm''' folder and drag and drop '''TS02_001sw02_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 '''sw02_001.gpkg'''. By default, all items in the available list should have been selected.
<li>In the QGIS Layers Panel, move '''sw02_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.

== GIS Data Entry ==
 
A GeoPackage called '''Urban_Development.gpkg''' is provided in the '''TUFLOW_SWMM_Module_02\Tutorial_Data''' folder. It contains seventhree SWMM input layers (and five other geometry input layers to be used later in the module):
:*'''Pipes''': defines the underground pipe network location, type and geometry.
:*'''Junctions''': defines the pipe network inlets.
:*'''Outfalls''': defines the pipe network outlet.
:*'''SWMM_Inlet_Usage''': defines the pipe network inlet details
:*'''2d_ztin_TS02_Development_001_R''': Topography update TIN region extent
:*'''2d_ztin_TS02_Development_001_L''': Topography update TIN lines

== GIS Data Updates ==
The provided GIS data requires numerous updates, prior to our model simulation. We have built these updates into this tutorial to demonstrate some of the available TUFLOW SWMM model built processing tools.
 
The following updates are being made to Objectsobjects and Layerslayers within '''TS01_002sw02_001.gpkg''' .
===Update SWMM Inlet Usage Layer Details===
An Inlet Usage Layer defines the physical location of inlets to the pipe network. It also defines some of the site specific geometry, such as inlet type, street cross-section reference, surface inlet elevation, placement type (on-sag and on-grade). To reduce data entry requirements for this tutorial, a complete Inlet Usage Layer has been provided, '''swmm_iu_TS02_001'''. It includes a variety of on-sag and on-grade inlets. On-sag inlets are used in locations where the inlet is located in an area of minimal longtudial slope. In this situation ponded surface water enters the pipe network. On-grade inlets are used where bypass flow is expected due to the inlet location being on a slope. For on-grade inlets, TUFLOW SWMM captures a percentage of the “approach flow” based on several factors including the total 2D approach flow, velocity and depth.<br>
 
<ol>
<li>Navigate to the '''TUFLOW_SWMM_Module_02\Tutorial_Data''' folder and save a copy of '''swmm_iu_TS02_001''' in the '''TUFLOW_SWMM_Module_02\TUFLOW\model\swmm''' folder.<br>
<li>Navigate to the '''TUFLOW\model\swmm''' folder. Drag and drop '''swmm_iu_TS02_001''' into the QGIS workspace.
</ol>
 
When you progress from this tutorial to project modeling, you will need to create an Inlet Usage Layer yourself. The template file for this is available from '''model\gis\empty\swmm_iu_empty.gpkg'''. The file is created during the initial 'Write Empty' step of the model build process (refer to <u>[[Tutorial_M01#Project_Initialisation | TUFLOW Tutorial Model 1]]</u>). A summary of the attributes within the Inlet Usage Layer is documented in <u>[https://docs.tuflow.com/classic-hpc/release/2023-03-AD/SWMM-TUFLOW-1.html#tab:tab-SWMMinletusage TUFLOW 2023-03-AD Release Notes (Table 4.1)]</u>
 
The 'Inlet' Attribute within '''swmm_iu_TS02_001''' is an ID reference to inlet geometry and associated information listed within '''sw02_001.gpkg''' >> '''Inlets--Inlets'''. A single inlet type, 'Combo1', was referenced in '''swmm_iu_TS02_001''' (the provided Inlet Usage Layer). In recognition of this, we need to create the entry for 'Combo1' in the '''Inlets--Inlets''' layer.
<ol>
<li>In the QGIS Layers Panel, select (left click) '''Inlets--Inlets''' and toggle on editing.
<li>Right click '''Inlets--Inlets''' and select 'Open Attribute Table'.
<li>Click 'Add Feature'. Enter the following attributes (leave all other fields as ''NULL''):
:*Name: Combo1
:*Type: COMBINATION
:*Grate_Length: 0.6
:*Grate_Width: 0.3
:*Grate_Type: P_BAR-50
:*Curb_Length: 0.9
:*Curb_Height: 0.15
:*Curb_Throat: VERTICAL
For a summary of the attributes associated with the '''Inlets--Inlets''' layer, refer to <u>[https://docs.tuflow.com/classic-hpc/release/2023-03-AD/SWMM-Input-Detailed-1.html#tab:tab-SWMM-Input-Inlets TUFLOW 2023-03-AD Release Notes (Table A.16)]</u> and the <u>[https://downloads.tuflow.com/SWMM/SWMM5_Reference_Manual_Volume2_Hydraulics_Addendum-20220210mas2wr.pdf SWMM5 Reference Manual - Volume 2 (Hydraulics Addendum) ]</u>
 
 
<li>Turn off editing to save the edits.

{{Video|name=Animation_TS2_SWMM_Inputs_05c.mp4|width=1236}}
<br>
</ol>
 
===Update Streets Details===
 
Street cross-section information is needed for SWMM on-grade inlet flow calculations. A single street cross-section type named 'Xsec1', is referenced in '''swmm_iu_TS02_001''' (the Inlet Usage Layer) using the 'StreetXSEC' field. <br>
We will now define this street cross-section type and its attributes.
 
<ol>
<li>In the QGIS Layers Panel, select (left click) '''Links--Streets''' and toggle on editing.
<li>Right click '''Links--Streets''' and select 'Open Attribute Table'.
<li>Click 'Add Feature'. Enter the following attributes:
:*Name: Xsec1
:*Tcrown: 7
:*Hcurb: 0.2
:*Sx: 4
:*nRoad: 0.014
:*a: 0
:*W: 0
:*Sides: 1
:*Tback: 5
:*Sback: 2
:*nBack: 0.016

===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 '''Conduits - Assign Node Fields''' tool from the Processing Toolbox.

<br>
</ol>
 
=== Create 1D/2D ConnectionsLinking===
The 1D SWMM / 2D TUFLOW linkage locations to connect the pipe network inlets to the surface have been already automatically defined in the SWMM Inlet Usage Layer, '''swmm_iu_TS02_001''', using the 'Conn1D_2D' attribute.
The following instructions introduce a new tool that automates the creation of 1D/2D connections. For 1D SWMM, HX lines are required from the upstream end of the culvert, and SX connections are used at the downstream end of the culvert.
<br>
<ol>
<br>
[[File:swmm_iu_TS02_001_attribute_table_Conn1D2D.png]]
<br>
</ol>
<br>
To complete the pipe network, 1D/2D linkage is needed at the outlet of the pipe network. The '<u>[[QGIS_SWMM_BC_Create_Channel_Endpoint_1D/2D_Connections |BC - Create channel endpoint 1D/2D connections]]</u>' tool will be used to automate this process.

==SWMM Options==
The model we are building will use two SWMM INP files.
*'''TS01_001sw01_001.inp''' was already created in TUFLOW SWMM Tutorial Module 1. It contained details defining the three embankment culverts under the roads crossingin the dominant flow pathsmodel. It also contained the associated 1D SWMM / 2D TUFLOW connection Layerlayer objects and the '''Project--Options''' necessary to execute the SWMM simulation. '''TS01_001sw01_001.inp''' has been included in the base model we are using for Module 2. No changes will be made to it. '''TS01_001.inp''' includes the Option commands necessary to execute a SWMM simulation.
* We will create a new INP file for the SWMM pipe network inputs (covered in the next Sectionsection). BecauseAs SWMM Options are already inculdedincluded in '''TS01_001sw01_001.inp''', they are not needed in this second (new) INP file. As such, no new SWMM Option commands are necessary for this tutorial.
'''Note:''' If '''Project--Options''' are included in multiple GeoPackage/INP files, the entry that is referenced lowest in the TUFLOW SWMM Control File (TSCF) will be used.
 
<br><br>
''Note: if more than one INP file includes SWMM Option commands, the details included in the INP file referenced lower in SWMM Control File (TSCF) will take precedence.
 
== Export SWMM INP File ==
We will now create a new INP file now for the SWMM pipe network inputs. To do this, we need to convert '''TS02_001sw02_001.gpkg''' into a SWMM INP file.
 
<ol>
<li>InRight theclick QGISon Layer Panel, selectthe '''TS02_001.gpkgLinks--Conduits''' andlayer rightin clickthe '''Links--Conduitssw02_001'''. Selectgroup (or any other SWMM layer in the same GeoPackage) and select 'TUFLOW' > 'SWMM - Export inp file'. This opens the dialog shown below.
<li>This will open the '<u>[[QGIS_SWMM_GeoPackage_Write_to_SWMM_inp |GeoPackage - Write to SWMM inp]]</u>' processing tool, prepopulated with the filename of the layer's GeoPackage. <br>
<li>Select '''TS02_001.gpkg''' as the GeoPackage Input File.
'''Note:''' This tool can also be activated from the Processing Toolbox.
<li>Set the SWMM output filename to '''TS02_001.inp''' in the '''''TUFLOW_SWMM_Module_02/TUFLOW/model/swmm''''' folder.
<li>Click 'Run'.
<li>Select "Run", then "Close" after the processing is complete.
<li>Once the tool is finished, click 'Close'.
<li>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 '''sw02_001.inp''' to the '''TUFLOW\model\swmm''' folder.

== TUFLOW GeometryBoundary UpdateUpdates ==
We will be using TUFLOW's 2D direct rainfall (also known as rain on grid) functionality for the catchment inflow boundary condition approach to demonstrate flows into the pipe network inlets. There is a wide range of direct rainfall options built into TUFLOW, including:
Set up the GeoPackage Database:
*'''Globally uniform rainfall:''' This method applies temporally varied rainfall uniformly (spatially) over the entire model.
*'''Spatially varying rainfall:''' This method applies temporally varied rainfall with spatial variation defined using polygon delineation, grid raster files or inbuilt TUFLOW TIN triangulation routines.<br>
<br>
The focus of this tutorial is not to demonstrate the available direct rainfall options. As such, we will be using the simplest approach, globally uniform rainfall. It does not require any GIS updates to implement the boundary condition change. Updates will be limited to the Boundary Condition Database reference and Control File syntax updates. Both are addressed in the next section. If you are interested in learning about the available direct rainfall options, please refer to <u>[[Tutorial_M06 |TUFLOW Tutorial Module 6]]</u>.
<br>

We will update TUFLOW's 2D elevation and landuse to represent changes associated with the urban development. The updates will be consolidated within '''TS02_001.gpkg'''.
 
Copy the following TUFLOW geometry inputs to GeoPackage '''TS02_001.gpkg''':
<ol>
<li>Right click anywhere in the QGIS Toolbar Panel and tick on 'Browser Panel' from the 'Panels' options.
<li>Within the QGIS Browser Panel, there is a dropdown directory, 'Project Home'. This directory is a shortcut to the location where the QGIS workspace is saved. In this case, it is a shortcut to the '''TUFLOW_SWMM_Module_02''' folder.
<li>In the 'Project Home' directory, navigate to the '''TUFLOW_SWMM_Module_02\Tutorial_Data''' folder.
<li>Drag the following layers (hold Ctrl to select multiple) from the '''Urban_Development.gpkg''' and drop them into the '''TS02_001.gpkg''' contained within the '''TUFLOW_SWMM_Module_02\TUFLOW\model\gis''' folder:
:*'''2d_mat_TS02_Dev_Buildings_001_R'''
:*'''2d_mat_TS02_Dev_Lots_001_R'''

= Simulation Control Files =
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.
<ol>
<li> Open '''TS01_5m_001.tcf''' fromin a Text Editor (Notepad++ is used here). Save the file as '''TS02_5m_001.tcf''' in the '''TUFLOW_SWMM_Module_02\TUFLOW\runs''''' folder in a Text Editor (Notepad++ is recommended).
<li>Using the 'Open File' function in Notepad++:
<li> Save a copy of '''TS01_5m_001.tcf''' as '''TS02_5m_001.tcf'''.
:*Open '''M02_001.tgc,''' and save the file as '''TS02_001.tgc''' in the '''TUFLOW\model''' folder.
<li> Open the following files using the Open File function in Notepad++:
:* Open '''TS01_001.tbc,''' and save the file as '''TS02_001.tbc''' in the '''TUFLOW\model''' folder.
:* Open '''M02_001TS01_001.tgctscf,''' and save the file as '''TS02_001.tgctscf''' in the '''TUFLOW\model''' folder.
<br>
