Introduction
This tool creates 1D/2D connections at the endpoints of SWMM channels. HX connections are created on the upstream end and SX connections are created on the downstream end.
Note: The positions of the HX and SX connections may not be completely accurate, so it is recommended for the user to check the output.
Usage
This tool, BC - Create channel endpoint 1D/2D connections, 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 Conduits Layer: The conduits layer to which the 1D/2D connections will be made. To only create connections for some of the conduits, select the desired ones and tick on 'Selected features only'.
- Offset distance: Distance from the channel endpoint to the midpoint of the BC line.
- Length of BC lines: Length of BC lines.
- Set 2D cell elevation to 1D culvert invert at 1D/2D connection cells if needed: If this is checked on, SX and HX boundaries will have the 'Flags' attribute set to 'Z'. This ensures that the valid elevations occur at the 1D/2D interface. HX boundaries require 2D cell elevations at or above the 1D elevation while SX boundaries require 2D cell elevations at or below the 1D elevation.
- Output Layer: Determines the location and filename of the output file. It is recommended to name the output layer with the prefix 2d_bc so TUFLOW styles can be automatically applied.
