Introduction

QGIS is used to review the intervention devices.

Review the Interventions

1. 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.
2. Click on the 'Apply TUFLOW Styles to Open Layers' symbol from the TUFLOW Plugin toolbar.
   
   
   
   
3. 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.
