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.
Note: This tool relies on the 'From Node' and 'To Node' fields to determine position in the network. The Conduits - Assign node fields 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 panel, navigate to 'Processing' in the menubar and select 'Toolbox'.
Parameters
- Input junctions: The existing junctions layer.
- 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).
- Input conduits: The conduits layer containing the channel(s) to which the junction and outfall node(s) are connected.
- Modified junctions layer: Determines the location and filename of the modified junctions layer (outfall node(s) removed).
- New outfalls layer: Determines the location and filename of the new outfalls layer.
