== Create Interventions ==
An interventions (2d_im) layer contains one or more lines, called devices. In the TUFLOW CATCH Control file, parametersmass removal properties are assigned to these devices which remove pollutants <font color=red> fix wording here</font>. TUFLOW CATCH will write an interventions summary that describes the total flows, masses entering and masses removed for all intervention devices and pollutants. <br>
 
Create the 2d_im layer using the TUFLOW CATCH plugin:
Line 22:
To help determine where the intervention devices should be placed, load in the following files:
*'''2d_mat_TC01_001_R.shp''' from the '''TUFLOW\model\gis''' folder
*'''TC01_001_catchment_hydraulic_d_Max.tif''' from the '''TUFLOW_CATCH_Module_01\Modelling\TUFLOWCatchTUFLOWCATCH\results\grids''' folder
 
Create interventions:
Line 28:
<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'.
