Tutorial M11 002 Check Files QGIS

Introduction

QGIS is used to import the check files and review the model.

Method

This tutorial introduces:

• _grd_check_R
• _1d_to_2d_check_R
• _nwk_C_check_L

Review the check files:

1. Open the following files from the Module_11\TUFLOW\check folder:

   • M11_5m_002_grd_check_R.shp
   • M11_5m_002_1d_to_2d_check_R.shp
   • M11_5m_002_nwk_C_check_L.shp

2. Use the 'Apply TUFLOW Styles to Open Layers'.
3. The 2d_grd_check file shows all active cells and confirms the 1D open channel is removed from the 2D domain including the 1D weir area at the downstream road.
4. The 1d_to_2d_check file contains the cells that transfer the water between the 1D and 2D domain:
   
   
   
   

   
   

5. The nwk_C_check file contains information on the 1D channels, bridges and weirs. Use the 'Identify Features' tool to inspect the attributes:
   
   
   
   

Conclusion

• The code layer was inspected to confirm the 1D weir location was deactivated from the 2D simulations.
• The cells connecting the 1D and 2D were reviewed.
• The 1D network layer was inspected, properties of the downstream bridge and weir reviewed.
