TUFLOW CATCH Tutorial M02 Check Files QGIS

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. 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.
   
   
   
   
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.
