Introduction

QGIS is used to create, import and view input data.

TUFLOW Project Configuration

Configure workspace to set empty file directory????

Method

A number of model input files have been provided in the TUFLOW_CATCH_Module_01\Tutorial_Data folder. Copy the following GIS files into the Modelling\TUFLOW\model\gis folder:

• 2d_bc_TC01_001_L
• 2d_mat_TC01_001_R
• 2d_bc_M03_culverts_001_P
• 2d_bc_M03_culverts_001_L
• 2d_bc_M03_culverts_001_R
• 1d_nwk_M03_culverts_001_L

Investigate the supplied files:

1. In Windows File Explorer, navigate to the Modelling\TUFLOW\model\gis folder. Drag and drop the above layers into QGIS.
2. Click on the 'Apply TUFLOW Styles to Open Layers' symbol from the TUFLOW Plugin toolbar.
   
   
   
3. The 2d_bc_TC01_001_L layer contains the downstream boundary:

   • It is a stage-discharge (HQ) boundary with a 1% water surface slope
   • This layer contains the downstream boundary from TUFLOW Tutorial Module 1. The upstream boundary was removed as TUFLOW CATCH does not support source??.

4. The 2d_mat_TC01_001_R layer contains the spatial definition of material types:

   • It is a supplementary material file to 2d_mat_M01_001_R, which is used in the TUFLOW tutorials. For more information, refer to TUFLOW Tutorial Module 1.
   • The material file is supplied with a QGIS style file (.qml) and displays the different material groups based on the Material ID.
   • explain the materials more? or just show in vid

   
   
   
   
5. The other supplied layers represent culverts. For more information, refer to TUFLOW Tutorial Module 3.
