== Review SWMM Check Files ==
When TUFLOW runs SWMM, it can accommodate for multiple INP input files within the SWMM Control file. TUFLOW combines the input INP files into a single combined INP file for the simulation execution. The combined file that TUFLOW uses is written to the '''TUFLOW/\results''' folder. The QGIS TUFLOW Plugin SWMM Processing Tool, '<u>[[QGIS_SWMM_GeoPackage_Create_from_SWMM_inp |GeoPackage - Create from SWMM inp ]]</u>' can be used to create a spatial GeoPackage version of the data for post simulation review checking.
 
<ol>
<li>In the Processing Toolbox, selectgo theto TUFLOW >> SWMM and select '<u>[[QGIS_SWMM_GeoPackage_Create_from_SWMM_inp |GeoPackage - Create from SWMM inp ]]</u>'. This opens the dialog shown toolbelow.
<li> Select: GeoPackage*SWMM Input File (inp): Navigate to the '''TUFLOW\results''' folder and select '''TS01_5m_001_swmm.inp'''.
<li>:*CRS Setfor GeoPackage: Click the CRSdrop fordown GepPackagemenu and select ‘Project CRS: EPSG:32760 - WGS 84 / UTM Zonezone 60S60S’.
<li> Leave :*SWMM Tags to ignore: leave blank.
<li> Set the :*GeoPackage output filename: Click the ... and select 'Save to File'. Navigate to the '''TUFLOW\check\''' folder and set the GeoPackage output filename to '''TS01_5m_001_swmm_check.gpkg'''.
 
<li>Click 'Run'.
<li>Once the tool ishas finished, click 'Close'.
<li>'''TS01_5m_001_swmm_check.gpkg''' will now be available in the '''TUFLOW\check''' folder.
:*<li>In Windows File Explorer, navigate to the '''TUFLOW_SWMM_Module_01\TUFLOW\check''' folder, and drag and drop the '''TS01_5m_001_CheckTS01_5m_001_swmm_check.gpkg''' into the QGIS. workspace and select the layers above (hold Ctrl to select multiple).▼
<li>When prompted by QGIS, under 'Options', tick on 'Add layers to group', then select 'Add Layers' to open all layers within '''TS01_5m_001_swmm_check.gpkg'''. By default, all items in the available list should have been selected.

== Review the TUFLOW Check Files ==▼
<ol>
<li>In File Explorer, navigate to the '''TUFLOW\check''' folder and drag and drop '''TS01_5m_001_Check.gpkg''' into QGIS.
<li> Open '''TUFLOW\check\TS01_5m_001_swmm_check.gpkg in QGIS. When prompted, open all Layers included in the GeoPackage file.
<li>When prompted by QGIS, under 'Options', tick on 'Add layers to group', then select '''TS01_5m_001_1d_to_2d_check_R''' and '''TS01_5m_001_grd_check_R''' (hold Ctrl to select multiple). Click 'Add Layers'.
▲<li> Review the '''Links--Conduit''', '''Node--Junction''', '''Nodes--Outfall''' and '''Project--Options''' information to verify the data matches the input values that were entered.
<li>Use the 'Apply TUFLOW Styles to Open Layers'.▼
<li>The grd_check[[Check_Files_2d_grd | _grd_check_R]] is the 2D grid defined by the 2d_code'''2d_code_M01_001_R''' layer and contains a region object for each cell. ItThis is a useful check file to understand how the model is orientated, and the 2D cell size in relation to the 2D hydraulic featurescontrols and where1D certainhydraulic calculations occur in the modelstructures. In this tutorial, the grid is orientated to align with the downstream road.▼

<li>The [[Check_Files_1d_to_2d_bc | _1d_to_2d_check_R]] file shows the cells selected by the SX boundary links (these connect the 1D SWMM objects to 2D TUFLOW). It is recommended that the number of selected cells has at least the width (i.e. cell side length x number of cells) of the associated 1D culvert. In this case, each cell is 5m wide and each 2D linkage is 10m wide.
<li>Zoom to each structure to inspect the HX and SX connections to ensure the '''2d_bc_SWMM_Culvert_Connections_001_L''' layer is appropriate.

<ol>
<li>Open the files, either:
:*Within the QGIS Browser Panel, navigate to '''TUFLOW_SWMM_Module_01\TUFLOW\check\TS01_5m_001_Check.gpkg''' and double click the following layers, or
::*'''TS01_5m_001_grd_check_R'''
::*'''TS01_5m_001_1d_to_2d_check_R'''
 
 
▲:*In Windows Explorer, navigate to the '''TUFLOW_SWMM_Module_01\TUFLOW\check''' folder, drag and drop the '''TS01_5m_001_Check.gpkg''' into the QGIS workspace and select the layers above (hold Ctrl to select multiple).
 
 
 
 
▲<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Use the 'Apply GPKG Layer Names'.
▲<li>The grd_check is the 2D grid defined by the 2d_code layer and contains a region object for each cell. It is useful to understand how the model is orientated, the cell size in relation to the hydraulic features and where certain calculations occur in the model. In this tutorial, the grid is orientated to align with the downstream road.
<li>The '''nwk_C_check_L''' file shows all attributes applied to the network elements. Some fields should be inspected as they have changes from the input '''1d_nwk_M03_culverts''' layer:
:*Len_or_ANA: contains the length used by TUFLOW (determined by the digitised line).
:*pSlope: the slope of the 1D element.<br>

<li>The '''1d_to_2d_check_R''' file shows the cells selected by the SX boundary links. It is recommended the same number of linking cells is selected at both the upstream and downstream of the culverts and that the number of selected cells is proportional to the structure size. Zoom to each structure to inspect the SX links:
:*The point SX selects a single cell in which the point falls. <br>
:*The region SX selects all cells where the cell centers fall within the region.
:*The line SX selects cells which are intercepted by the line using the crosshair approach. For example, the dashed lines below are the hidden crosshairs within a cell. An SX line must intersect at least one of these crosshairs to be selected:<br>
