== Introduction ==
This tool converts junctions on the downstream side of a network to outfall nodes as required by SWMM. ThisAn tooloutfall useslayer with the "Fromconverted node"nodes andwill "Tobe Node"created fieldsalong towith determinea positionmodified injunction thelayer (outfall nodes networkremoved). EnsureThe thatcontents of these fieldslayers areneed populatedto andbe upcopied tointo the appropriate layers in the SWMM dateGeoPackage.<br>
 
'''Note:''' It is recommended to use the <u>[[QGIS SWMM Conduits Assign Node Fields|Conduits - Assign Node Fields]]</u> tool and the <u>[[QGIS SWMM Integrity Make Node Names Unique|Integrity - Make Node Names Unique]]</u> tool to avoid errors when running the simulation.
'''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.

== 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:''' SelectThe theexisting ..junctions layer. button to bring up a dialogue and then navigate to the location of the GeoPackage to convert.
<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:''' Select the ... button to bring up a dialogue and then navigate to the desired location of the SWMM inp file.
<li>'''Input conduits:''' The conduits layer containing the channel(s) to which the junction and outfall node(s) are connected.
<li>'''New outfalls layer:'''
<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.
