== Introduction ==
An interventions (2d_im) layer is created to remove pollutants from the run off around the paddocks and within the waterway. <br>

<br>
<li> Set up the QGIS workspace by setting the projection to EPSG:32760, seeloading and styling the DEM and saving the workspace. See <u>[[TUFLOW_CATCH_Tutorial_M01_Project_Initialisation_QGIS#Coordinate_Reference_System_.28CRS.29 | TUFLOW CATCH Module 01 - Project Initialisation]]</u> for details.

Line 28 ⟶ 27:
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: ClickThis ...,should andautomatically navigatebe 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 36 ⟶ 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>

Line 51 ⟶ 49:
<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>

<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>
