= 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 first completing TUFLOW SWMM Module 1 beforeprior to starting this tutorial. <br>

Set the new Output Database name to '''TS02_001.gpkg'''.
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.
<li>Delete the pre-filled "Incremented Layer" entry. 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.
 
<li>Select '''Remove Source Layer from Workspace'''.
<ol>
<li>Select '''Increment Layer and Preserve Database'''.
<li>In the QGIS Layers Panel, select (left click) '''2d_bc_M01_001_L'''.

==Create SWMM GeoPackage Spatial Database==
We will create a new SWMM GeoPackage database for our pipe network feature entries:
<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 the …, and tick on (if not already ticked):
:*:*'''ProjectNodes--TitleJunctions''', '''ProjectNodes--ReportOutfalls.'''
:*:*'''NodesLinks--Junctions'''Conduits, '''NodesLinks--OutfallsStreets.'''
:*:*'''Links--Conduits, LinksInlets--StreetsInlets.'''
:**'''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'''.
::'''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 Tutorialtutorial 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 tothe tool has finished, click ‘Close’.
<li>In Windows File Explorer, navigate to the '''TUFLOW\model\swmm''' folder and drag and drop '''sw02_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 panelPanel, 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 three 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.
Line 103 ⟶ 113:
 
<br>
To populate the GeoPackage database created in the previous section:
<ol>
<li>In Windows File Explorer, navigate to the '''TUFLOW_SWMM_Module_02\Tutorial_Data''' folder. Drag and drop the '''Urban_Development.gpkg''' into QGIS.
<li>When prompted by QGIS, under 'Options', tick on 'Add layers to group', then select '''Pipes''', '''Junctions''' and '''Outfalls''' (hold Ctrl to select multiple). Click 'Add Layers'.
<li>In the QGIS Layers panelPanel, right click on the '''Pipes''' layer and select 'Zoom to Layer(s)'.
<li>Use the 'Select Features' tool to highlight all items included in '''Pipes'''.
<li>Select 'Edit' from the top QGIS tab and 'Copy Features' from the drop down menu.
<li>SelectIn the QGIS Layers Panel, select (left click) the '''Links--Conduits''' layer in the Layers panel by left clicking on it once.
<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_TS2_SWMM_Inputs_02bAnimation_TS2_SWMM_Inputs_02d.mp4|width=12351236}}<br>
<li>Similarly, copy the objects from '''Junctions''' into '''Nodes--Junctions'''. Junctions are considered inlets, and should be defined at the upstream end of isolated culverts and all upstream ends of pipes within a network.
<li>Also copy the objects from '''Outfalls''' into '''Nodes--Outfalls'''. Outfalls are treated as outlets, and are required at the downstream end of isolated culverts and the most downstream end of a pipe network.
<li>Toggle off editing to save the edits.
<li>Remove '''Urban_Development.gpkg'''.
<br><br>
{{Video|name=Animation_TS2_SWMM_Inputs_03aAnimation_TS2_SWMM_Inputs_03c.mp4|width=12351236}}<br>

Line 132 ⟶ 142:
The following updates are being made to objects and layers within '''sw02_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 aan 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>
Line 139 ⟶ 149:
</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 layerLayer 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''' Layerlayer.

====Node Details====
 
The 'From Node' and 'To Node' attribute information in '''Links---Conduits''' 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.
