==SWMM GIS Data Updates==
We will make SWMM GIS updates to sw02_002.gpkg (pipe network) and sw03_001.gpkg (hydrology).
The Node--Junction attributes in sw02_002.gpkg (pipe network) will vary depending on whether a hydrology subcatchment has been linked to the Junction or not. As such, establishing the sw03_001.gpkg (hydrology) features first is recommended.
===Update SWMM Hydrology--Raingage===
The following updates shall be made to sw03_001.gpkg. <br>
The information within '''Hydrology--Raingage''' (Note: 'Gage' is the American spelling of 'Gauge' in Oxford English) defines the pluviographs in the catchment. We will link to two different rain gages in this example.

===Update SWMM Nodes--Junctions===
Now the SWMM hydrology inputs are complete, we will make the necessary changes to Nodes--Junctions in sw02_002.gpkg. The following updates shall be made to sw02_002.gpkg. <br>
<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 Inlet Usage Layers: '''swmm_iu_TS02_001'''
:*Input BC Connection Layers: '''2d_bc_SWMM_Pipe_Network_Connections_001_L'''
:*Nodes recieving subcatchment flows (if connected to 2D): Set Apond = 0.0; Ksur = 0.0 (overwrites options below)
:*Nodes connected to 2D with Inlets (Ysur): 0
:*Nodes connected to 2D with Inlets (Area of ponding): 25
:*Nodes connected to 2D without Inlets (Ysur): 0
:*Nodes connected to 2D without Inlets (Area of ponding): 50
:*Nodes without 2D Connection (Surcharge Depth): 50
:*Nodes without 2D Connection (Area of ponding): 1
<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 '''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-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>.
