== Introduction ==
An interventions (2d_im) layer is created to remove pollutants from the run off around the paddocks and within the waterway. <br>
 
== TUFLOW CATCH Project Re-Configuration ==
Re-configure the TUFLOW CATCH project to use and save empty files to the correct folders:
<ol>
<li>Go to Processing > Toolbox from the top drop down menu options to open the Processing Toolbox.
<li> Go to TUFLOW Catch in the processing tool list and select 'ImportCreate TUFLOW Catch EmptyProject'. This opens the dialog shown below.▼
* Project Name: '''TC02'''
:* Project DirectoryFolder: Click '...', and navigate to the '''TUFLOW_CATCH_Module_02\Modelling''' folder.▼
* Project CRS: Click the drop down menu and select 'Project CRS: EPSG:32760 - WGS 84 / UTM zone 60S’.
* TUFLOW HPC Executable: Click '...', and navigate to the '''exe\TUFLOW\2025.1.0''' folder. Select '''TUFLOW_iSP_w64.exe'''.
* TUFLOW FV Executable: Click '...', and navigate to the '''exe\TUFLOWFV\2025.1.0''' folder. Select '''TUFLOWFV.exe'''.
* Default GIS Format: Click the drop down menu and select 'SHP'.
* Tick on 'Create Empty Files'.
<li> Click 'Run' and a console window will open. This creates the empty GIS files.
<li> Once the tool has finished, click 'Close'.<br>

<br>
<li> Set up the QGIS workspace by setting the projection to EPSG:32760, loading and styling the DEM and saving the workspace. See <u>[[TUFLOW_CATCH_Tutorial_M01_Project_Initialisation_QGIS | TUFLOW CATCH Module 01 - Project Initialisation]]</u> for details.

== Create Interventions ==
An interventions (2d_im) layer contains one or more lines, called intervention devices. These intervention devices may represent constructed wetlands, bioretention systems, grassed swales, riparian revegetation strips or similar features. In the TUFLOW CATCH Control file, each device is assigned mass removal properties, arewhich assignedcan tobe thesedefined devices.and TUFLOWadjusted CATCHon willa writepollutant anby interventionspollutant summarybasis. thatThe describeslocation theand totalorientation flows,of masseseach enteringdevice andis massesspecified removedvia forlines allin interventionthe devices and2d_im pollutantslayer. <br>
 
Create the 2d_im layer using the TUFLOW CATCH plugin:
<ol>
<li>Go toIn the Processing > Toolbox, fromgo to TUFLOW Catch in the topprocessing dropdowntool menulist optionsand toselect open'Import Empty'. This opens the Processingdialog Toolboxshown below.
:* Project Directory: This should automatically be set to the '''TUFLOW_CATCH_Module_02\Modelling''' folder.
▲<li> Go to TUFLOW Catch in the processing tool list and select 'Import Empty'. This opens the dialog shown below.
▲:* Project Directory: Click ..., and navigate to the '''TUFLOW_CATCH_Module_02\Modelling''' folder.
:* Empty Type: Click ..., and tick on '2d_im' from the empty type list.
:* Geometry Type: Click ..., and tick on 'Line'.
Line 16 ⟶ 34:
<li> Click 'Run'. Once the tool has finished, click 'Close'. The '''2d_im_TC02_001_L''' will appear in the QGIS Layers panel. <br>

Create interventions:<br>
<ol>
<li>In the QGIS Layers panel, select (left click) '''2d_im_TC02_001_L''' and toggle on editing.
<li>Select 'Add Line Feature'.
<li>Digitise a line around the corner of the paddock with material ID 9 (paddockD). Use the right mouse button to terminate the line, and an attributes dialog will appear. Set the ID to 'trench1' and click 'OK'.
<li>Repeat the same process as above to digitise a line between the road and the paddock with material ID 7 (paddockB). Set the ID to 'retentionBasin'.<br>
<br>
{{Video|name=animation_TC2_GIS_inputs_01a.mp4|width=1236}}<br>
<li>Zoom in to the downstream end of the model. Use the '''TC01_001_catchment_hydraulic_d_Max.tif''' to determine where the water will be flowing. Using the same process as above, digitise a line perpendicular to the water on the western side of the stream. Set the ID to 'bufferStrip1'.<br>
<br>
{{Video|name=animation_TC2_GIS_inputs_02a.mp4|width=1236}}<br>
<li>Create two more intervention devices with ID's 'trench2' and 'bufferStrip2'. Use the image below as a guide. <br>
'''Note:''' To style the interventions, use the "Apply TUFLOW Styles to Open Layers" [[File: TUFLOW_apply_styles_open_layers_icon.png | 30px]] and the "Apply Label to Current Layer" [[File: TUFLOW_apply_label_icon.png | 40px]] tools from the TUFLOW Plugin toolbar.<br>
<br>

<br>
<li>Once all the intervention devices have been created, turn off editing to save the edits.
