== Introduction ==
This tool converts junctions on the downstream side of a network to outfall nodes as required by SWMM. An outfall layer with the converted nodes will be created along with a modified junction layer (outfall nodes removed). The contents of these layers needsneed to be copied into the appropriate layers in the SWMM GeoPackage.<br>
 
'''Note:''' This tool relies on the "'From Node"' and "'To Node"' fields to determine position in the network. The <u>[[QGIS SWMM Conduits Assign Node Fields|Conduits - Assign node fields]]</u> processing tool will ensure the "'From Node"' and "'To Node"' fields are correctly assigned.
<br>
 
== Usage ==
This tool, '''Junctions - Downstream junctions to outfalls''', can be found in the QGIS processing toolbox panel under 'TUFLOW >> SWMM'. To open the Processing Toolbox Panelpanel, navigate to 'Processing' in the menubar and select 'Toolbox'.<br>

=== Parameters ===
<ol>
<li>'''Input junctions:''' The existing junctions layer to be converted. To only convert some of the junctions, tick on 'Selected features only'. The tool will only convert the junctions which have been selected.
<li>'''Selected features only:''' If node(s) in the junctions layer have been selected using the 'Select Features' tool, this option will become available. If checked on, the tool will only check the selected node(s).
<li>'''Input conduits:''' The conduits layer containing the channel(s) to which the junctionsjunction and outfallsoutfall node(s) are connected.
<li>'''Modified junctions layer:''' Determines the location and filename of the modified junctions layer (outfall nodes removed). Details on the options are below. ▼
<li>'''NewModified outfallsjunctions layer:''' Determines the location and filename of the newmodified outfallsjunctions andlayer junctions(outfall layersnode(s) removed).
▲<li>'''ModifiedNew junctionsoutfalls layer:''' Determines the location and filename of the modifiednew junctionsoutfalls layer (outfall nodes removed). Details on the options are below.
