Introduction
QGIS is used to review the intervention devices.
Review the Interventions
- In Windows File Explorer, navigate to the TUFLOWCATCH\check folder and drag and drop TC02_001_catchment_hydraulic_im_check_L.shp and TC02_001_catchment_hydraulic_grd_check_R.shp into QGIS.
- Click on the 'Apply TUFLOW Styles to Open Layers' symbol from the TUFLOW Plugin toolbar. This will style the _grd_check_R layer. To make the _im_check_L clearer, right click the layer and select 'Properties...'. In the 'Symbology' tab, set 'Width' to 0.7mm.
- The _im_check_L layer shows where the interventions have been applied, and their lengths. Notice that the lines step around the grid cells. This occurs because interventions use a cell face based calculation to remove pollutants. This calculation looks at the flux going across every cell face that the line intercepts with.
