M02 Arc Check Files Archive

Introduction

In this page we will review the 1d network check file and the 1d/2d check files in ArcMap. The check files are very useful for confirming the inputs to TUFLOW have been correctly inputted.

1D Network Check File

The 1d network check files contain all of the 1D channels. This can be particularly useful if multiple 1d_nwk layers have been inputted. It also contains some of the properties such as % slope.

1. Load the M02_5m_001_nwk_C_check_L.shp from the TUFLOW\check\1d\ folder.
2. For each of the culverts there should be a summary of the final culvert properties.





If there are no objects in the layer or the file does not exist check that:


• The correct TUFLOW simulation M02_5m_001.tcf was started;
• The .tcf file has the 1D commands entered correctly; and
• The .tcf file has been saved.

1D/2D Check File

The _1d_2d_check file contains information about the 2D cells that are connected to the 1D culverts.

1. Import the M02_5m_001_1d_to_2d_check_R.shp from the TUFLOW\check\2d\ folder.
2. At each of the culverts there should be some shaded 2D cells.
3. At the culvert where we used the "SX" points in the 2d_bc layer. There should be a single cell upstream and downstream of the culvert, as per the image below.</li.
   

   
   

4. At the culvert which we used the "SX" line method, there should be three 2D cells upstream and downstream of the culvert.





If there are not connections cells at all of the culvert locations check that:


• The correct TUFLOW simulation M02_5m_001.tcf was started;
• The correct version of the check file was opened;
• The .tcf file has been updated to refer to the new .tbc file M02_5m_001.tbc and has been saved; and
• The .tbc file been updated and saved.

Conclusion

The check files have been used to confirm that the model inputs are correct. By now the model should have finished running and we can review the results.
