==Review TUFLOW FV Check Files==
Open the following check files from the '''TUFLOWCatch\check''' folder into QGIS:
:*'''TC02_001_receiving_mesh_check_R.shp'''

<li>Click on the 'Apply TUFLOW Styles to Open Layers' symbol from the TUFLOW Plugin toolbar.
<li>The receiving_mesh_check is the TUFLOW FV model domain defined by the '''Stream_Mesh.2dm'''. For each cell, it contains:

* '''CTRDX''' and '''CTRDY''': The X and Y coordinates of the cell center.
* '''Mat''': The material ID applied in the cell.
* '''ZB''': The elevation of the cell center.
* '''BRough''': The bed roughness (Manning's n) value of the cell.

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.
