<li>The 2d_zsh landscape files create a TIN elevation footprint of the development,. seeThe 2d_mat file contains polygons that represent the updated land use due to the topography changes. See <u>[[Tutorial_M02_002_GIS_Inputs_QGIS | Module 2]]</u> for more information.<br>
<li>The 1d_nwk layers represents pits and pipes. The pipes are a series of circular culverts with a set Manning’s roughness value. The pits are set up as a series of Q type pits to convey flow into the pipe network via SX connections. SeeRefer Section 5.4 ofto the <u>[https://downloadsdocs.tuflow.com/_archiveclassic-hpc/TUFLOWmanual/Releaseslatest/2018-03/TUFLOW%20Manual.2018-03.pdf 2018 TUFLOW Manual]</u> for more information on the attributes. <br>

<li>In the Run ID box write 'M05_outlet_001'.
<li>Tick the 'Lines' Geometry Type and hit 'OK'. The 2d_bc layer appears in the QGIS Layers panel.
<li>Right click on the ‘2d_bc_M05_outlet_001_L’'''2d_bc_M05_outlet_001_L''' and toggle on Editing.
<li>Digitise a CN (connecting) line from the downstream pipe and a SX line to allow flow to transfer from 1D to 2D.
<li>Enable snapping and use the 'Edit Advanced Configuration' tool to select '''2d_bc_M05_outlet_001_L''' and '''1d_nwk_M05_pipes_001_L'''.
<li>Right click on the ‘2d_bc_M05_outlet_001_L’ and toggle on Editing.
<li>Select 'Add Line Feature' and digitise a line snapped from the downstream end of the pipe.
<li>Terminate the line by right clicking and write 'CN' (connection) into the 'Type' attribute.
<li>Add another line snapped to the end of the CN line and enter 'SX' as the 'Type' attribute to allow flow to transfer from 1D to 2D.
<li>Turn off editing to save the edits.<br>
