The second'''<u>[[1D_Integrity_Tool_-_Channel_ID|Channel ID]]</u>''' integrity tool, checks the ID of each channel link in the TUFLOW 1D network and flagflags channels that have duplicate names or a NULL / empty ID. The tool also has a processing option to automatically correct these instances.

3.<li> Return to the '''Channel ID''' tool, and deselect the option to '''‘Flag non-compliant channel IDs’''' and select the option to '''‘Fix non-compliant channel IDs’'''.
4.<li> For duplicated node ids we will use the option to '''‘Append number to duplicate IDs using delimiter (default delimiter is _ e.g. pipe1_1, pipe1_2 etc):’'''
5.<li> For null or empty IDs, set an option for Type ‘C’ and Prefix ‘Pipe’. The resulting dialogue should look like the below:<br>

6.<li> Click run'''Run''' to fix the non-compliant channel IDs. Again, choose the option to update the Input Network Lines to the new layer.
7.<li> Run the Channel ID integrity tool on the resulting '''1d_nwk_MI01_Pipes_001_L_EG1_ID1''' to confirm that all names have been corrected. If successful, you should get the message that ‘All channel IDs were compliant’.
8.<li> Check the IDs within the attribute table for the '''1d_nwk_MI01_Pipes_001_L_EG1_ID1''' layer.
