View source for QGIS SWMM Junctions Downstream Junctions to Outfalls

== 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 need 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 panel, navigate to 'Processing' in the menubar and select 'Toolbox'.<br>

=== Parameters ===
<ol>
<li>'''Input junctions:''' The existing junctions layer. 
<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 junction and outfall node(s) are connected. 
<li>'''Modified junctions layer:''' Determines the location and filename of the modified junctions layer (outfall node(s) removed). 
<li>'''New outfalls layer:''' Determines the location and filename of the new outfalls layer.
