QGIS is used to import the check files and review the pipes and pits network connected to the 2D domain. <br>
Line 15 ⟶ 12:
Review the check files:
<ol>
<li>Open the following files, from the ''' Module_05\TUFLOW\check''' foldereither:
:*Within the QGIS Browser Panel, navigate to '''Module_05\TUFLOW\check\M05_5m_001_Check.gpkg''' and double click the following layers, or
:*'''M05_5m_001_grd_check_R.shp'''
::*'''M05_5m_001_nwk_C_check_L.shpM05_5m_001_grd_check_R'''
::*'''M05_5m_001_pit_A_check_P.shpM05_5m_001_nwk_C_check_L'''
::*'''M05_5m_001_pit_A_check_P'''
::*'''M05_5m_001_1d_to_2d_check_R.shp'''
 
:*In File Explorer, navigate to the '''Module_05\TUFLOW\check''' folder, drag and drop the '''M05_5m_001_Check.gpkg''' into the QGIS workspace and select the layers above (hold Ctrl to select multiple).
 
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Use the 'Apply GPKG Layer Names'.
<li>The grd_check'''grd_check_R''' is the 2D grid defined by the 2d_code layer and contains a region object for each cell. It is useful to understand how the model is orientated, the cell size in relation to the hydraulic features and where certain calculations occur in the model. In this tutorial, the grid is orientated to align with the downstream road.
<li>The '''nwk_C_check''' file shows all attributes applied to the network elements. Some fields should be inspected as they have changes from the input '''1d_nwk_M05_pipes''' layer:
:*Len_or_ANA: contains the length used by TUFLOW (determined by the digitised line).
:*US_Invert: set to the DS_Invert value of the pit snapped to the upstream end.
Line 31 ⟶ 29:
For example, for Pipe 5:
:*Len_or_ANA: 36.52m based on the digitised line length.
:*US_Invert: set as the DS_Invert of Pit 16 as specified in the '''1d_nwk_M05_pits''' layer.
:*DS_Invert: set as the DS_Invert of Pit 15 as specified in the '''1d_nwk_M05_pits''' layer.
:*pSlope: value of 0.5 (US_Invert - DS_Invert / length).

<li>The '''pit_A_check''' file shows the pit locations and the attributes applied from the 1d_nwk pits file.<br>

<li>The '''1d_to_2d_check''' file shows the cells selected by the 1d_nwk pits, a single cell per pit, and the cells selected by the outlet of the pipe network (SX line). This is where the water enters the 2D domain from the 1D network. <br>
